I have been getting messages from other QTH/QSL hosted mailing lists stating that inbound messages to my account are being rejected and this started on the 1st.  I haven?t received one from GreenKeys but I noticed no one has posted this month. 

If anyone else had an issue I would like to know.  I have my own mail server and I haven?t made any changes so I am not sure what?s going on.

 An obscure Teletype Corporation research project was the development of a
TV system for video-conferencing and similar applications.
Unfortunately it never made it beyond the prototype stage and only a short
test video <https://www.navy-radio.com/tty/video/teletype-tv.gif> has
survived.

April 1st??

Seriously though, I've gotten messages before telling me of things wrong 
with my email account that needed to be fixed (by logging in of 
course).? It sounded authentic, said I was almost at my storage limit.? 
I was keeping an awful lot of history.? The provider was not one of the 
big guys, more of a mom and pop operation.? It made me change my 
password and get rid of a bunch of stuff and modify my archiving 
system.? I made sure I went to the site via my bookmark and not the link 
in the message.

You said "tomorrow" yesterday.

Yeah I am still not receiving anything.  The only reason I got this one is because I was directly addressed on it.  I received bounce messages from MRCA, Milsurplus pretty much anything from the QTH/QSL system.  I am still getting the groups.io stuff.  

So I figure my provider must have made some sort of change over the weekend.  I will figure it will work itself out hopefully.  

Thanks for the response.  I am still getting them though autostart so old technology wins again. Hi hi

Does your mail server have a TLS certificate that expired on 4-1?

Try checktls.com

I just started receiving emails from other lists.  I contacted the ISP (actually one of my friends and they had enabled a white list based on another company).  They had been getting blocked as a purveyor of spam so are working to clean up the problem areas I guess.

Message-ID: <CAF6Vb56PbK5=h03+_KVGBtm016-PjL9XD0axfKM6v2OvmJXXHw@mail.gmail.com>

I've got a couple extra SB-1203 patch panels that I'm never going to
need.  Each one has rheostats to adjust current in up to six different
loops and a switched meter.  They make for a very compact and neat way
to tie all your teletype gear together.

I'd like to get $50 a piece. I can ship, of course. They're too big
for a flat-rate box, but not terribly heavy.

Thanks,
de Robert W7MKA

Thanks to Lawrence Godek for the paper copy. The IRL FSK-1000 manual is
now available at https://w6iwi.org/rtty/IrlFsk1000.pdf . The schematic was
across several pages. I've pasted them back together using GIMP. Some
misalignment, but I think it's readable.

For anyone who buys a 1203 from R.H. Goff make sure to download the book
from navyradio. It is a small book but it is essential.

Even with the book it took me nearly a week to install my 1210 and work the
bugs out.

Now I like it very much.  I have loops 1, 2 and 3 wired for remote power
from three terminal units with built-in loop supplies. 4, 5 and 6 use local
loop power. I plan to key two of those with relays, I have a 120 VDC power
supply that is capable of running those three loops with ease.

I always keep one locally powered loop free for testing individual
Teletypes,

For remotely powered loops be sure to short the appropriate fixed
wirewound  resistors. The remotely powered loops must be wired the reverse
of the locally powered ones to have the meter read  to the right on all
loops.

I wired my Teletypes to the "set" jacks. The abiIity to patch is amazing. I
also chose to wire my "misc" jacks into each vertical loop to give me an
extra patch point. I have two excellent external meters that I patch there,
so I can meter three loops at once. They also show me that the meter on the
my 1210 is not very accurate. It reads low.

Test each loop as you wire it. Then kill all loop supplies as you wire the
next Loop.

A few Tips learned the hard way!

Tom, are you saying the 1203 has a built-in loop supply (local power)? I noticed in RH?s pictures that one was taller than the other. What is the difference between them?

NO built-in supply. Normal use is to attach a supply to two terminals. That
powers six separate loops, each with fixed current limiting resistor,
rheostat, and jacks.
IF you want to power a loop from a separate supply (like built-in to a
Dovetron), there are jumpers to change the source. If that separate supply
already has current limiting, then you should jumper the 1203?s fixed
resistor for that loop, as Tom said.
This is an excellent device to connect all your equipment together with
lots of flexibility.
The manual is here
https://www.navy-radio.com/rtty/sb1203.htm

The ?extension? on top is just a cover for cable exit if wanted.

Subject: [GreenKeys] Teletype ASR model 33 restoration
Message-ID: <2ad9017e-6931-018c-eb9a-d5b840ab4bb6@gmail.com>

Hi,

Recently I recovered 2 model 33 teletypes from 1976. Both are the same, 
and both haven't been plugged since 30+ years. The old man who gave them 
to me got them at his factory when they decommissioned those. His plan 
was to plug them to each other in 2 different rooms for his kids to play 
with them. He never did.
So, having both, I started to restore one, keeping the other one for 
spare parts.
Here is a picture of one before I start cleaning:

https://imgbb.com/D7k8By0

They have been modified by a retailer for France use (220V 50Hz).
So I cleaned one, de-greased and re-greased most of it, changed a broken 
ball bearing shaft (taken from the other one), checked the relays were 
not stuck (with a 12V lab psu) and replaced the rubber hammer on the 
print head with a rubber tube (the 40yo rubber hammer was turning into 
some sticky nasty gum).
I'm close to make it work locally. I still have to fine tune some 
settings and make the Carriage Return work, but the four blocks work 
(just with a very low reliability on decoding characters).
My intent was to use Mike's "current loop to rs232" adapter ( 
https://deramp.com/tty_adapter.html ), but the P2 connector looks a 
little bit different. Its pin 3 isn't wired (which is where the adapter 
gets power from).

https://ibb.co/YTMGV4n

https://ibb.co/TRKfJ3z

https://ibb.co/fF83Yxd

So, the UCC neither a UCC-6 or a telex. I don't even know if P2 
connector is wired as the one on UCC-6.

Has anyone seen that kind of UCC ? Does anyone has some information or 
documentation about it ?

And does anyone know about decoding reliability or carriage return issue 
? I already ordered new capacitors to replace all of them, as it can't hurt.

Thank you

Ben

Hello Ben,

this is the European version, mainly used for CNC tooling machines.

Join telexforum.de and have a look at this thread:
https://telexforum.de/viewtopic.php?t=1785

Teleprint 390 is a "repacked" 33ASR in another enclosure with similar
control electronics
like yours.
They were sold in Europe both in original cover as well in a more
rugged one as Teleprint 390.

Thank you Nick, for answering those questions before I even saw them, for
filling in a couple details I forgot and for providing the link to the
manual.

If one uses an the external power supply to power all six loops, remember
that is 60 mils times six or 360 mils. 360 mils is the max output on my
supply. I did not want to push it to its limit. I only use it to run three
loops, so it loafs along at 180 mils.

One more comment - I think Goff's price is very reasonable considering how
useful these units can be. I was lucky, I got my 1210 for free, but I would
not hesitate to pay his price for a 1203 if I needed one.

Study the wiring of the "set jacks". When you patch into one to get access
to a teletype, the Teletype is disconnected completely from its loop and
the loop is bypassed by contacts on the jack. Then you are free to patch
that machine to any other loop. As I said - it is amazing!

By the way the 1203 has six "set jacks" the 1210 has twelve "set jacks" of
which I am only using only five - four model 28 printers and a dome reperf.
Unused "set jacks" must be bypassed on their terminal strips to complete
those loops. My first four loops are connected to an SB6-GG which is a
similar, but non-powered, patch panel for four loops. I have that in the
basement where I have my three 15's. It is a very useful accessory to the
1203/1210.

If I'm not mistaken, they have diodes and resistors (and maybe caps) in
line to isolate each loop channel. In working at the ship with 24 loop
panels I wondered the same thing, although in those cases it seems most of
the loops/panels are a mix of loops and just straight equipment jacks.

Thanks Nick! I rely on your extensive documentation collection. I also
really appreciate the Teletype equipment I picked up from you at Dayton a
few years ago.

 Nope, no diodes or capacitors. No, the loops are not interconnected except
sharing a common negative lead (usually ground). The plus lead of the loop
is isolated via the current limiting resistors. Loop 1 doesn't care whether
Loop 2 is 60ma or 0 ma. The one thing that you can't do is stick a
grounding piece of gear (like a TU) into the middle of a loop, because then
devices downstream in that loop get bypassed..

plus---fixed resistor---rheostat----TTY1----TTY2----TU1----minus (ground)
plus---fixed resistor---rheostat----TTY3----TTY4----TU2----minus (ground)
etc.

Each loop or circuit contains the following jacks:

   - *LPG (looping jacks)* normally closed circuit contact phone jacks. Any
   teletypewriter patched to LPG jack with patch cords is connected in series
   in that particular channel, two or more LPG jacks are provided in each
   channel;
   - *SET (set jacks)* the jacks labeled SET incorporate a
   double-throw-double-pole switch; by inserting a DUMMY PLUG into the SET
   jack, the teletypewriter originally in this channel is disconnected;  by
   inserting a patch cord into the SET jack, the teletypewriter originally
   connected is removed from the circuit and can be patched to any other
   circuit by inserting the patch cord into the LPG jack of the desired
   circuit;
   - *MISC (miscellaneous jack)* these jacks are normally closed contact
   phone jacks identical to the LPG jacks; the MISC jacks are not wired to any
   particular circuit; teletypewriters not normally assigned to a converter or
   other terminal equipment are internally connected to the MISC jacks and are
   then available for patching to any circuit.

*"NOTE: Anyone patching or unpatching circuits from a TTY panel must be
sure to pull the plug from the looping jack (LPG) before removing the other
plug from the SET (machine) jack. Pulling the SET jack first interrupts all
TTY message traffic on that channel. IT ALSO PRODUCES A DANGEROUS DC
VOLTAGE ON THE EXPOSED PLUG!"*

I think on mine, which is a SB-2244 that was intended for crypto gear, I
wired the set terminals to the corresponding misc port, so I could then
plug in a fixed teletype from the front, then I have both looping jacks OR
I can easily patch the machine to another loop without removing the main
cable.

If anyone has parts from one of these (specifically the knobs and
rheostats) I'd love to convert the crypto loops on mine to standard loops.
I'd need 3 rheostats and 3 knobs, then it basically becomes an SB-1210.

Or if one of these are still available I'd be interested in one.

One power supply can power many loops if  it will supply the current.  Just as your 120 volt wall socket if you plug in an adaptor or dropcord.  You just have to limit each loop seperatly to 60 ma.

I?ve always wondered how one power source could supply six loops. Don?t they each need a dedicated loop supply? Or are all six channels joined together into one loop?

NO built-in supply. Normal use is to attach a supply to two terminals. That powers six separate loops, each with fixed current limiting resistor, rheostat, and jacks. 

IF you want to power a loop from a separate supply (like built-in to a Dovetron), there are jumpers to change the source. If that separate supply already has current limiting, then you should jumper the 1203?s fixed resistor for that loop, as Tom said. 

This is an excellent device to connect all your equipment together with lots of flexibility. 

The manual is here

The ?extension? on top is just a cover for cable exit if wanted.

For anyone who buys a 1203 from R.H. Goff make sure to download the book from navyradio. It is a small book but it is essential.

 

Even with the book it took me nearly a week to install my 1210 and work the bugs out.

 

Now I like it very much.  I have loops 1, 2 and 3 wired for remote power from three terminal units with built-in loop supplies. 4, 5 and 6 use local loop power. I plan to key two of those with relays, I have a 120 VDC power supply that is capable of running those three loops with ease. 

 

I always keep one locally powered loop free for testing individual Teletypes,

 

For remotely powered loops be sure to short the appropriate fixed wirewound  resistors. The remotely powered loops must be wired the reverse of the locally powered ones to have the meter read  to the right on all loops.

 

I wired my Teletypes to the "set" jacks. The abiIity to patch is amazing. I also chose to wire my "misc" jacks into each vertical loop to give me an extra patch point. I have two excellent external meters that I patch there, so I can meter three loops at once. They also show me that the meter on the my 1210 is not very accurate. It reads low.

 

Test each loop as you wire it. Then kill all loop supplies as you wire the next Loop.

 

A few Tips learned the hard way!

Message-ID: <E2CDA22B-0CBD-48B5-B8C3-C8B300A2F89E@junknet.net>

Still working on a Navy CV-3510 demod. Same one as I mentioned before, except I made some headway with it and it seems to be in a much better place but not quite there yet. (Really only in CRT, I had it copy 8 minutes of TTY flawlessly yesterday).

As part of the adjustment instructions, it had me connect the input and output jacks together and enable "retransmit", which technically creates a loop. Interestingly the crt just had a bit of a dim square to it. Then it said to enable reverse, which put it into a tizzy, yet the instructions said to adjust a signal at a test point for minimal AC, butit was a really crazy waveform and adjustment wasnt changing anything.

So should that kind of setup create an oscillating mess like Im seeing? I may have to readjust again, the mark signal is now clean and perfect on the CRT, but space is still an oblong oval. (These adjustments are for balancing them out)

The bottom one in this pair, which I thought was working well, I tried to use it as a reference, but it turns out to have its mark/space freq all out of wack so that'll be next.

So there I was, as snug as a bug and in the Land of Nod, when a strange

I was in a room full of Teletypes, and someone was trying to give me a 37 
(I think).

That someone?

There was a bit more to it than that of course, but the nature of dreams

Anybody using the Remex tape reader ( I was interested in the series 9000) ? Does it work for Baudot and ascii ?
Looking for manual please. Does it get connected into the local loop ?

I saw one in Eugene's shack tour.

Curious about why all the interest in Navy equipment.  What about the army, air force, etc. ?
Since I am Canadian, I'm not familiar with all the military gear.

To answer the question regarding Navy gear, Im volunteering on the Battleship New Jersey, which is a museum ship, trying to get some TTY gear running again. The demods Im working on were a pair I brought home that were more or less malfunctioning at the ship, due to age, bad caps, and who knows what else.

I know theres other groups interested in other military gear like Army and all, but Navy, with the ships, used Teletype gear pretty heavily, especially over radio, hence lots of TTY gear made specifically for the Navy. Some of those ships are now museums, and Im not sure you'd find a decommed Army barracks as a museum (great something to Google).

(Actually, Infoage in NJ was a former Army Barracks turned museum, but all former Army anything there is long gone, except for the Project Diana dish which was restored. It definitely has that Beetle Bailey vibe though.)

Hi Fred,

Hopefully someone here has better information, but the several Remex 
readers I worked with were all ASCII and parallel output. They were part 
of computer machine tool controls (early automation)

Why Navy? Well I?m just a nut about US Naval Communications and have
created a miniature message processing center. The US Navy bought Model 28
gear exclusively for almost 40 years. The first 6000 Model 28s went to the
Navy. Daniel is restoring Model 28 gear on board the USS Iowa museum ship
and Jeff is doing the same on board USS New Jersey. Every Navy ship was a
miniature message processing center with multiple teletypes. So that drives
some of the traffic. Maybe there is just more Teletype Corp gear in
circulation and that overlaps with US Navy use. And RCN too I think. If you
aren?t familiar with Jerry Proc?s RCN site, it is a delight to explore.
http://jproc.ca/rrp/index.html


The US Army bought Kleinschmidt gear after WW2 and the USAF bought both
Kleinschmidt and Teletype gear. While they had large message processing
centers, I don?t know of anyone attempting to recreate one.  A number if
people do restore tactical RATT stations with one or two Kleinschmidt
pieces.

Nick K4NYW, having fun?.

Our power has been off three times in the last few weeks. Twice yesterday
alone. Each time I have to run around shutting off computers and
uninterruptible power supplies before the batteries die. Also two laptops
that at least are not so critical on batteries.

So each time I disappear from the internet without warning. I am back up
again now.

In addition my desktop which runs Retype,  TTY Artwork and Icecast keeps
crashing. I do not know why except it is not a memory problem.When I notice
it has crashed I drop everything and bring it back up.

http://n3crk.ddns.net:8000/tty -  News (updated daily)

n3crk://ddns.net:8000/retype - Very old news (Never changes)

n3crk://ddns.net:8000/ttyart - TTY Artwork (Always in good taste) (Never
changes)

I recently eliminated some pictures that were too wide and added a few new
ones.
I also changed the URL to "ttyart" which I felt was more descriptive of the
content.

http://n3crk.ddns.net:8000/850 - News at 1575 Mark and 2425 pace The same
news as the 170 shift stream but not in sync with it,

All my streams are 60 speed.

I spend two or three hours a day updating my two news steams but I rarely
see anyone on them. I an starting to wonder if it is worth the effort. I
could better spend that time working on my own Teletype Collection.

I used one the other day, I was looking for the 850 one but somehow,
leaving the demod in HF mode (so 1575/2425), it just...works somehow. (The
demod does have a 170hz mode but its centered on 1500).

I may try the 850 either tonight or tomorrow if I mess with the demods
again. Ready to recap the second one and get them off my bench.

So curiosity got the best of me yesterday and I did some googling to see
what other military teletype installations may still be around. Really the
Navy stuff is probably a bulk of it, since they used so much and in
designated "places" (ships) that may still be preserved. I didn't expect to
find much on Army or Airforce comms type places as they'd all be remodeled
or redone when obsolete, however I did find this page that seems to have a
couple surviving portable rigs: https://rattrig.com

Then I also came across this vid showing some 28s banging away at the
Airforce:
https://www.criticalpast.com/video/65675031248_US-Air-Force-Communications-Center_United-States-Air-Force_receivers_dials_teletype-machines

And of course there's other small museums and such around like Duncan's
that has a bunch of this stuff spanning all depts as well.

Does anyone else know of any "surviving" installations - meaning - places
where TTYs were used originally, and are still there? I guess KPH probably
counts (https://www.radiomarine.org/radio-archaeology/kph-kleinschmidt)

This guy sent me email a while back asking what it was and when I explained
how it was used, he replied ?nah, man, I wanna know what kind of great
sounds it will make?
$700 for a Quick Brown Fox ?techno sound generator?.
I guess we?re not the only crazy people out there??

One of the US Army's first easily transportable (and could be used in 
motion) RTTY/RATT stations? was the AN/GRC-46.? It was later replaced by 
the GRC-142.

Here is a 1963, US Army, film introducing the GRC-46:

 The navy was still using ALL CAPS to send messages up until 2013!Not sure but I think this practice had it roots in Teletype.Maybe Nick can explain that one.

Just went through my pics and I found a couple pics - it was a
AN/UGC-143A(V). One of them I think had a ribbon still in it, and it looked
like that, thanks I'll check that out.(and maybe stash the ribbon in a safe
spot if they're hard to come by).

ALL CAPS predates Teletype use. Radiomen copied Morse using a ?mill?
typewriter with no shift needed - all caps, a 1 key, and a slashed zero. So
all messages were in ALL CAPS format with no confusion between O and 0 or 1
and L.
When the change to upper-lower case came, the Wall Street Journal ran an
article, illustrating it with a drawing of a MITE. I was disappointed it
wasn?t a M28, but they probably wanted to save column inches.

I?m in process of taking my model 19 apart for repainting. It?s a steel desk.?Im going with black wrinkle powder coating.?I?m wondering what kind of wire did teletype use to wire these tables with? They?re cloth covered and very flexible although it seems the wire color dye has faded. I?m assuming they might have used Western Electric wire type.?
I?m also looking for a rec 30 power supply for it. I?m located in Wisconsin.?

Hi Tom,
Thanks for all your work with the TTY streams.
As we are all working on restoring these old machines, it's nice to have
multiple sources for exercising them.
Sometimes I notice that the copy is only about 90% so not sure if it is the
audio levels or shaping on my end or what. Maybe others can comment.
Thanks again,
Jon N5MHI

It would probably be a good idea to have a central site with links to all the available streams.  Since yours has been up for a good length of time you would more than qualify.

I could register a web-site and put all of them together (the links would be the only thing on the site). Or perhaps someone could add a prominent east to find area on their site.

Either way I think many getting into it expanding the hobby would benefit.

I like it.

I never noticed before that Tom had one with the military tones, nice to 
have it when you're trouble shooting one of those converters.

Perhaps you could add the tone frequencies for Greenwich too?

Message-ID: <cd82377d-3ffe-0475-4abf-e5afd018335a@earthlink.net>

All-caps typewriters were also used by Western Union for telegrams that were phoned in, and
probably before that for Morse reception.  Also used by radiotelegraph companies for the high
speed Morse (up to 500 wpm or so by radio) that was received on ink recorders and transcribed
by typists.  And there were Army radio sets in shelters that used CW prior to radioteletype.

The Western Union typewriters looked like ordinary commercial typewriters of the period except
that the metal front panel was red rather than black.  I'm only speculating that this was intended
to distinguish company-owned typewriters from those owned by the individual telegraph operators.
Apparently typewriters were marketed to telegraph operators as individuals when they wanted
to copy easier and faster than they could do by handwriting.

Eugene,

Thanks!!

That is just what we need, all the info on one page! (and it doesn't 
need to be fancy)


But is it just for Teletype Corp machines?

What about Kleinschmidt, Teleprinter/MITE, Siemens, Lorenz, Creed, RFT, 
MMTTY, Fldigi, etc. ?

To be more generic, you should label it "Teletypewriter News Services"

(just a little rant left over from brain-washing working at Xerox. Corp.)

Thanks & have fun,

Duncan

Subject: [GreenKeys] M28ASR wiring
Message-ID: <ddea4dfd-a749-3c09-fa4f-ece903c34757@earthlink.net>

I'm trying to set up a M28ASR and I need to find the rear terminal strip 
connections for the printer, keyboard, tape reader and aux reperf. The 
unit was from a civilian installation, but is referred to as a "UGC-6" 
on the patch panel.

I've tried to find a basic connection diagram from the documentation on 
Nick's site, but as Nick once said:

    /"Sometimes I think the Teletype publications group was run like a
    super-secret govt project - each group wrote about its own little
    piece, but no one knew how it all got connected
    together.......except for the document package shipped with each
    machine which was always discarded within two weeks."/


Can someone just give me the rear panel terminal strip connections for 
the i/o's to/from the cabinet?

I will be wiring everything on separate loops.? When I switch from 
"LINE" to "TEST", does everything get put into the one local loop?

Thanks,

Duncan

I?m looking forward to hearing what you find out, and what you do. 

Eugene recently figured out his 28ASR and made a diagram. Mine was different than his and thus far I have been unable to figure it out. I wonder if there is any consistency among machines.

Jeffery,

Thanks, but I l have that document and it is very hard to follow.

I did find some schematics at 
http://rtty.com/development/teletype/model28ASR/index.html which look 
more helpful. (although there are rfreferences to "Notes" which are not 
there.)

John,

Perhaps ITTY - Europe has the tones you are asking for.

I'm familiar with the "airline" drawings. They are fine if you want to 
know where a pin or terminal on a connector connects to, but doesn't 
answer my original question of where on the rear terminal strip does the 
external loop connect.

The schematics on the RTTY.COM page help.? It looks like the external 
loop connects to terminals C5 & C15.

I generally like the ones that say something like:
28ASR with LESU13
115vac circuits at top. Loop circuits at bottom.
The terminals at rear are Cxx. This is not a very good scan but I am on my
phone and searching is hard. More later.
https://www.navy-radio.com/manuals/tty/jh/ttyman9/drawings/m28-13.pdf


It depends on the LESU of course, but loop terminals are almost always the
same C

And the military, of course, had to redraw things using TBxx, Jxx, Pxx,
etc. but that correspondence is relatively easy to decode.
Here?s the UGC-6 version.

Nick,

I found that "m28-13" drawing on RTTY.COM.? It is relatively easy to 
read, especially the way they separate the AC & DC circuits. There are 
notes referenced on that drawing, but not on the drawing. Is there 
another page that goes with it?

The link for the UGC-6 you sent me 
https://www.navy-radio.com/tty/asr/ugc6-schem-01.pdf just gives a blank 
pdf page.

Thanks,

Duncan

Firefox has its own pdf view, but it apparently doesn't like the UGC-6 pdf.

As john said, downloading the pdf first, then opening it with Adobe 
works.? Looks like a good schematic

Thanks,

Fred,  I have a few of these. They take 1 inch tape (8-level) and some are parallel and others are serial. But if you can punch Baudot on the top (or bottom) 5 of the 8 bits and do the same with the reader, it can be used to store baudot. But probably too much effort. My plans are to use them with a PDP-8e and PDP-11s I have a bunch.

Hi Fred,

Hopefully someone here has better information, but the several Remex readers I worked with were all ASCII and parallel output.  They were part of computer machine tool controls (early automation)

You said "tomorrow" yesterday.



The above comments or recommendations are SWAG. Use at your own risk.

Anybody using the Remex tape reader ( I was interested in the series 9000) ? Does it work for Baudot and ascii ?
Looking for manual please. Does it get connected into the local loop ?

I saw one in Eugene's shack tour.

Curious about why all the interest in Navy equipment.  What about the army, air force, etc. ?
Since I am Canadian, I'm not familiar with all the military gear.

Subject: [GreenKeys] M28 ASR full duplex?
Message-ID: <185bfd11-a9e5-9464-baa1-b97b05f754f2@earthlink.net>

I'm mainly a Kleinschmidt guy, and I have never had to dig into the M28 
wiring before.? Other than change a couple of motor-start capacitors, my 
M28s have just run.

But now that I am getting into this M28 ASR wiring for our TMC station, 
it looks like the M28 (especially the AN/UGC-6) was mainly used with TX 
& RX in just one loop.

Was the M28 ever used in full-duplex (separate TX & RX loops)?

Ham TUs like HAl & Dovetron would take one loop and separate the TX & RX 
signals.? But what about military units like the CV-2460?? Just looking 
at the manual, it looks like it needs separate TX & RX connections from 
the TTY, but the UGC-6 does not seem to offer that option. (At least not 
from looking at the UGC-6 schematic, Fig 12-38.)

 From the Teletype Corp. schematics, I can see that the M28 ASR has very 
flexible wiring and you could bring out the keyboard contacts 
separately.? But I'm surprised that the UGC-6 schematic doesn't show 
that option. Or is there another schematic to show separate TX &RX wiring?

Thanks,

Duncan

Duncan, I don?t have the LESU that you have (probably) but all of the possible connections do come out to the rear barrier strips. You definitely can separate RX and TX on these if you want to. The CV-2460 allows both full duplex and half duplex operation. For full duplex you use all 4 connections. For half-duplex you put 2 of the 4 connections in series and pull off the other 2 connections for the teleprinter. 

Check out page 119/136 in this PDF. Look at option "3" is the half-duplex set up.
https://w2hx.com/?prefix=x/CV-2460/

good luck

As Eugene says, all the connections are on the terminal strips connected so
you can do whatever you want. But standard usage for all the Navy M28 KSRs
and ASRs that I have seen so far have a single loop connection with
keyboard and printer in series (also TD in the ASR).
Maybe because you wanted to also print what you were sending? But what do I
know.....
nota bene - the 28ASR K-KT-T switch would let you cut a tape locally while
printing from elsewhere.

Eugene,

Thanks,

I see now how the TX & RX of the? CV-2460 terminals can be strapped 
together.? (I had not seen the rear panel of the CV-2460 and assumed 
there were connectors)

My main question was how is the UGC-6 used in full duplex operation?? 
Fig 12-38 does not show that option.

Sorry, no extra rack ears.

The CV-2460 allows both full duplex and half duplex operation. For full duplex you use all 4 connections. For half-duplex you put 2 of the 4 connections in series and pull off the other 2 connections for the teleprinter.

Subject: [GreenKeys] asr dual TDs
Message-ID: <mailman.960.1680983477.3596.greenkeys@mailman.qth.net>

I am watching this subject with interest as I have a 28asr that had a 
spider web of non original loose wires inside that I removed. The 
original wiring to the
terminal strips is in good shape. This asr has what looks to be 
factory dual TDs. I am thinking I will series them but do not know how
the original wiring was connected but maybe someone here can enlighten me.

As Eugene says, all the connections are on the terminal strips 
connected so you can do whatever you want. But standard usage for all 
the Navy M28 KSRs and ASRs that I have seen so far have a single loop 
connection with keyboard and printer in series (also TD in the ASR).
Maybe because you wanted to also print what you were sending? But 
what do I know.....
nota bene - the 28ASR K-KT-T switch would let you cut a tape locally 
while printing from elsewhere.

They just weren?t used in full duplex (except if the aux typing reperf was
independently connected). Normal installation was to the C-1004 box that
you manually switched from CFS REC to CFS SEND. (The TONE position was for
hookups that automatically keyed the xcvr, usually UHF).
https://www.navy-radio.com/rtty/c1004.htm

I guess I just don?t understand when you would run full duplex using a
single TTY.
If you wanted to receive while transmitting you just used an additional TTY
printer or reperf.

On the NJ, each model 28 actually has 4 loop connections. Now they were wired as low level, but looking at the panel the keyboard, printer, and TDS were all seperate loops so definitely possible to do full duplex. In the low level ESA, there was a jumper wire for having the printer in line with the keyboard.

On the converters, yes they have seperate input and output, but the manuals say you can just jumper across the plugs for a half duplex arrangement.

Other than the drive I spent all day today inside a 28. I smell like a 28. I think I can taste it too. Not as good as it smells LOL.

It took me waay longer than I expected to splice a bunch of wiring back together, and Im way more sore than I expected lol. (I had to fix some AC wiring in the base).

I would bring a shop vac in and vac out all that rotten foam.  It just plugs up the works once it gets hot and the machine runs for awhile.  Plus it will keep the insides looking better.  

Excellent work bring that stuff back to life.

Subject: [GreenKeys] Needed: 28 ASR harness or parts
Message-ID: <182248A9-8716-4DE3-855B-15CE46C44301@junknet.net>

So Im officially asking to speed up the process, but I could use any complete factory harness sections other than AC stuff for a 28 ASR. Specifically:

- Keyboard base to terminals section (if I could fine one thing this is the part Id love to find)

- Any reperf wiring, like aux reperf to lid (or reperf, Im not sure which one is considered the "aux", but the far left one that goes to the lid switches

- Print mechanism to terminals (not sure this is needed; I think the wiring just goes to unused terminals but I need to verify

Last but not least, a pair of 45.5 baud gears for the reperf. I found a set for the main motor.

This is to help bring back a "decommed" 28 on the battleship NJ. Almost every part of the harness was cut or cut such that a "section" was removed. Thankfully the AC stuff was just cut and I had just enough slack to splice it back together.

If you have anything feel free to reply here or privately, I check email often. Thanks!

In digging into a M28 ASR, I think I have stumbled across some of the 
differences between Army & Navy TTY communications.? All the schematics 
for M28 KSR & ASR units that I have seen, show just one loop, tying the 
TX & RX circuits together. (Aux reperf in a M28 ASR typically has its 
own loop.)? M28s are wired such that they are very flexible and can be 
wired to separate TX & RX circuits, but that is typically not how they 
are shown on system drawings.? Th AN/UGC-6 (M28ASR w/aux reperf) 
schematic (fig 12-38 from the Navy manual ) does not show an option for 
full duplex (separate TX & RX loops) operation.

Nick says that full duplex was not used much (if any) in the Navy TTY 
comms, but his page, https://www.navy-radio.com/circuits.htm does 
mention full-duplex operation.

In 1950, the Army (and Army-Air Force) started buying Kleinschmidt 
equipment exclusively (although they did buy some? M28s later.)? All the 
Kleinschmidt units, TT-4, TT-76, TT-98, AN/FGC-25 were set up for full 
duplex operation with separate cables or jacks for TX & RX. The standard 
Army wire-line modems (TH-5 & TH-22) used with the TTYs were capable of 
both simplex (2-wire) and full duplex (4-wire) operation.? Mobile RTTY 
huts (AN/GRC-26, -46, -122) could all be operated full duplex, though 
simplex was the norm. (the AN/GRC-142 is a simplex GRC-122.)

I was a TTY repairman in the Army Security Agency. In Viet Nam in 1967. 
I was in the 337th Radio Research Co., supporting the 1st Infantry 
Division. We were located near the Division HQ and had outstations 
(AN/GRC-46 huts) positioned with the forward located 1st ID Brigades.? 
We also had a link to our battalion HQ and that link carried a lot of 
traffic; so much so that it was run in full duplex mode, with messages 
going in both directions, simultaneously.

The outstations had tape facilities (TT-76s), but our company comm 
center just consisted of a hut (AN/MSA-?) with four TT-4 printers, 4-5 
KW-7 crypto units and four TH-5 modems in it. So all outgoing messages 
had to be typed on-line.? Imagine typing a message on a printer while 
another message is being printed!

The Army did have medium-sized comm centers in trailers or vans and big, 
fixed station comm stations, but I never saw them. I did work on a 12 
channel tape-relay center that was in a 38 ft trailer..

So maybe some of the difference between Army & Navy operation was due to 
the Army units being smaller and more spread out; vs. the Navy with 
concentrations of operations on big ships. The Navy's use of multiplexed 
RTTY may have given them enough channels that they did not need to 
operate full-duplex.

Just some thoughts.

Have fun,

Duncan

Low-level signalling!? There is another variable and reason you cant put 
TX & RX all on one loop.

I will probably spend most of Tuesday inside the AWA Museum's M28 ASR 
doing some rewiring.

Yes big differences between Army and Navy ops at the unit level. Big
message processing centers were more alike.

When the Navy ran full duplex it was to separate TTYs, one for transmit and
another for receive. Nobody tried to type on the machine that was printing,
except for cutting tape which functioned via direct mechanical keyboard to
perf connection and didn?t interfere with printing. Then when it was your
turn to transmit, you would run that tape through the TD.

The UGC-6 (28ASR) was used in duplex systems as a transmitting TTY while
another TTY was printing (or punching tape).

Mainly, ships received the fleet broadcast on TTY printers. There was no
transmission back from the ship, just reception of messages from shore
stations.

Ships also participated in nets, but that wasn?t full duplex.

Even a smaller ship might have 10 TTY units aboard (counting TD, ROTR, KSR,
ASR)

Disclaimer- this is from what I have read and studied. I have no first-hand
operational experience.

In the middle 1960's, The Army trained me as a cook and sent me to Fort
Riley, Kansas. (By the way, the very best cook there was a former
helicopter pilot.)

I managed to talk my way into electronics and ended up at the receiver
site. My first experience there was tuning in a RTTY signal. ( I had
already spent a couple years at home copying RTTY off the air.) I had a
heck of a time tuning in the other station with an unfamiliar receiver.
Eventually I realized our own transmitter was still operating on the
simplex frequency. I told the guy at the com center he needed to turn our
transmitter off to receive. His response was the he had copied a little bit
(Without a clue that what he copied came from the receiver site.)

He did start unkeying the transmitter. I guess things worked better. But
that was almost 60 years ago.The only thing I remember clearly was that
guy's stupidity.

That "ship-75a" figure gives a good feeling for the complexity of a Navy

At first, I didn't understand Nick's statement.
But then I realized it is another Army/Navy, Kleinschmidt/Teletype Corp. 
difference.

A M28 KSR/ASR always had a an ESU with a local loop and a line relay for 
isolation from the line. So you could have a low level "loop" feeding 
the M28 and then the ESU converted the low level to high level to feed 
the selector magnets.

Kleinschmidt machines never included a isolating line relay. Except at 
the large comm centers, they normally connected directly to a wire line 
modem or FSK converter. A low-level TX signalling connection was made 
directly to to the crypto equipment which would typically be only a few 
away.? There was no low-level signalling on the RX side from the crypto 
gear. From the 1950s through the 1980s, crypto gear was KW-9 (until mid 
1960s), KW-7, & KW-26.

Seems like a reasonable price for a Model 28 "twletypewriter" motor.

Item Number 234900899376 on E-<part of the coast where the land curves in
so that the sea is surrounded by land on three sides>.

Would suggest making offer to seller. I added item to my watch list, and
received offer.

No idea of condition. Not affiliated with seller.

Just for clarity - the Teletype terms were LESU and ESA-

LESU - model 28 Electrical Service Unit located in back of the motor in RO,
KSR, and ASR cabinets. Could have line relay, autostart relay, internal
loop supply, selector magnet driver, etc. In NON-TEMPEST units the external
high-level (current loop) signals went through the LESU and then to
selector magnets and keyboard contacts. In TEMPEST units, the LESU handled
AC circuits but not any signals.

ESA - Electrical Service Assembly was a double shielded gold-colored box
used in TEMPEST units. Contained cards to convert external low-level
(+/-6v) signals. Included a selector magnet driver (SMD) connected via
shielded cable to shielded selector magnets. For KSR and ASR it included a
low-level keyer (LLK) to convert very low current keyboard signals (via
shielded cable) to +/-6v signals. The LLK connected to the outside world
and also to a second SMD input so that the printer would echo the keyboard.
This low-level link was wired inside the ESA box. There was also a separate
clutch magnet driver (CMD) ESA for driving the keyboard and TD clutches to
sync with crypto equip pulses if necessary.

https://www.navy-radio.com/tty-tempest.htm

Shipboard, the black side ran high-level 60ma current loops and the red
side ran low-level +/-6v signals.

All this would be much easier if we were drawing on paper napkins over a
beer?..

Ken -
Are the dual TDs LXDs? I had a 28 ASR with what appeared to be LXDs however one of them was an LX - parallel output. This was a special system for the Air Force I was told and the LX was supposed to feed a computer. Also, the machine was all 100 wpm and there were no 60 wpm gears for the TD arrangement.

I am watching this subject with interest as I have a 28asr that had a

original wiring to the
terminal strips is in good shape. This asr has what looks to be 
factory dual TDs. I am thinking I will series them but do not know how
the original wiring was connected but maybe someone here can enlighten me.

Ken, Tim et al,

I was going to ask if it looked like to regular TDs, or one of them was 
a climber.? It will make a difference on the wiring.? The common two 
head would be LXD single contact TDs.? Unless one's a LX? (or maybe all 
doubles are 1 LXD and 1 LX, might be some logic to that?).

The climber would be an LCXD and you can only use one at a time since 
they share the same distrubutor.? (I wonder if they ever made a version 
with an LD mounted on the LCXB so you could use them independently?)

Then for various ides on ASR wiring,

FAA: https://www.navy-radio.com/manuals/tty/28ASR-FAA-IMD-D-439.pdf

You can ignore the right hand side pretty much and there are a couple of 
extra features on the left as well.

WU: https://www.navy-radio.com/manuals/tty/wd/wu9797wd.pdf

You most likely don't have that one, but if you ignore terminal numbers 
in many cases, it's another way to illustration how things work.

WE: (Western Electric, Teletype's parent) 
https://www.navy-radio.com/manuals/tty/wd/w0700-6105.pdf

Navy: https://www.navy-radio.com/tty/asr/ugc6-schem-01.pdf

It is helpful when looking for documentation to have all the name plate 
data you can find.

Unfortunately you will find Teletype model numbers, Bell System numbers 
or JAN (military) numbers on the equipment.? Later military manuals seem 
to have Teletype number in them.

Teletype models for 28 and 35 equipment are like LP9 for printer, LK21 
for keyboard, and LMU3 for motor unit.

Bell Systen uses number like 28B printer, 28B keyboard? 28E cabinet.? 
28x is useless without a word description to go with it. (I really don't 
like their system)

There are various charts that will reference you back to the Teletype 
number (or the other way around depending on what documents you have) 
from Bell or military numbers.

BSPs will have either Bell System numbers or Teletype model numbers or 
sometimes only a word description for a title.

Bulletins are AFAIK are all strictly Teletype documents.? (Maybe not?? I 
now recall seeing Bell numbers in some)

Personally I prefer BSPs, only because I was brought up on them years 
ago.? You really need to try all varieties to work out puzzles at times. 
Fortunately they all use Teletype part numbers, although you'll see if 
you were a Bell System employee you'd add TP as a prefix.? Military 
makes you work for it with all their tables and references back and 
forth.? Later ones seem better. Teletype and Bell put the P/N right on 
illustrations in the parts sections.? Earlier military manuals used 
their own reference numbers that then had to go to the tables to find 
the real number.

Back in the late 30s through the early 60s. Top craftsmen of the Bell System and IBM were required to wear appropriate clothing? a collared shirt, long trousers and a tie when working inside buildings. As a Teletype and Data Communications Serviceman in 1966 I had to meet these requirements minus the tie, as like our foreman found out his tie could and did get caught in the platen when inspecting the 35 ASR I had just finished routine maintenance.

And on Sunday's many added a jacket.  These days blue jeans seem to be acceptable anywhere.  I don't have a problem with that.

I always wondered about the IBM guys with their blue suits and white
shirts and having to work on punch card machines that might be greasy.
Eventually I saw an IBM tech wearing a sort of brown smock over his
clothing.

Teletype R&D circa 1963 we all wore white shirts and ties and slacks.
I don't know of any official code but that's what we all wore, except
a few higher-ups who wore suits.  Someone who addressed a meeting in
the auditorium remarked about the blinding brightness of all those
white shirts.

One of my vexations in winter was going out to shovel the snow out of
my driveway in the morning, then going back in to change into proper
work attire and having the snowplow come by and bury my driveway again.

When I worked for G.E. Computer in the mid 1960s the enginers dressed 
pretty much the same.  But it was a tradition in Phoenix for everyone to 
wear "Western wear" for Rodeo Week.  I was amused that G.E. posted a 
lengthy notice in the plant saying we were not to dress up Western during 
Rodeo Week.

I like the idea of dress codes for skilled craftspeople. It was required 
for maintenance people in the elevator craft by most companies. Some 
customers in large cities demanded the technician enter the building in 
coat and tie, and then change into coveralls they provided before doing 
the work. There were bathrooms designated with good soap and hand 
cleaner, good towels, and reliable hot water. You had to clean up and 
take off the coveralls before going to lunch or break. I think it 
fostered pride in the workers. Were there any women working as teletype 
maintainers, if so what was their uniform?

I can totally relate to that!  I taught high school for 33 years and 
nearly every day I wore a shirt and tie to work, up to and including my 
last day of classes when I retired in 2019.  The only exceptions were 
school spirit days which meant a school T-shirt, or a teacher conference 
day when there were no students around.  My district was notorious for 
calling a weather (snow day) closing at the last possible moment and 
there were many snowy mornings I'd go out and clear the driveway, go 
back inside and dress for work and hear the news flash on the radio just 
as I finished tying my tie that school had been called off for the day. 
If school wasn't closed, then the plow had more than likely come by and 
filled the end of the driveway by the time I was finished dressing.

Fun times ... ?

Tom,

Just wanted to say thanks! for putting up a 850Hz stream.? It was very 
helpfull checking out an old FSK converter at the Museum today.

I did notice that the AFSK tones seemed to pause (with a mark) for a 
short period (one or two characters?) every once in a while (seemingly 
random times).? Still having some minor problems with the converter, but 
i don't think the pauses caused any garble.

Were you aware of that?

Thanks,

Duncan

Message-ID: <CAB55hNenm4sNjffoy8zwi-2iwLOe+_pSYi3KKfWru6PMT-x+Ow@mail.gmail.com>

I'd like to test my machines and FSK converters by sending a text file from
my Windows 7 machine. I don't want to do anything other than set mark/space
freq and speed. Everything I find wants to control my transceiver, display
waterfalls, automatically reply 599, enter into logbook, etc. and I can't
figure out how to just send audio.
I don't want to hook up a COM port (not even sure if I have one) - just
plug into the headphone jack and drive my Dovetron.
I need something Simple, just like me.

Any recommendations?

I generally use ITTY to test stuff. For Android devices (including
Chromebooks), there's Droid RTTY. I also test with "impaired" audio and
other stuff at https://w6iwi.org/rtty/audio/ . To generate single tones,
Visual Analyzer does a great job (and is also an oscilloscope, THD
analyzer, frequency counter, and spectrum analyzer).

Good luck!

I just use Fldigi - I think you can even run two copies side by side if you
want, one can be your daily driver and another could be with no config. I
think.

One thing to keep in mind that I found out - the tones a PC can generate
can be slightly off - probably not by much, but a little, so for example if
you have your RTTY signal 850shift centered on 2000, it may be 1580 and
2420, something like that. (It shouldn't matter for most of what we do, but
it -can-)

Thanks to all for the recommendations. I?ll look at the ones suggested. I
often use ITTY or Tom?s streams for testing, but sometimes I want a
particular format, or to punch tape from an existing file.

An update and MMTTY helpful hint.
Thanks to Tom K3CRK I now have MMTTY working. I kept trying to say to heck
with it, but Tom stuck with it, requesting screen shots and offering
suggestions.
Curse all computers! Reboots, configuring MMTTY, re-installing MMTY,
closing every other program, tearing my hair out, etc. all failed to get
anything other than "sound card not found" from MMTTY. Of course the
speaker output from the sound card works just fine for other applications.
What the???

Well, (at least on this Windows 7 machine) if there is nothing plugged into
the MIC jack, it doesn't think there is a "recording device" and if MMTTY
doesn't find a "recording device" for reception it throws up its hands and
will not transmit. So I put a dummy plug in the MIC input and MMTTY started
behaving.

Nick,

I am glad you finally got it. But it has nothing to do with Windows. It has
everything to do with your computer hardware that won't let the on-board
sound card work until it sees something plugged into a jack.

Now go and use MMTTY in peace, my son.

Nick or anyone using MMTTY,

Ii found these very helpful. Open the "TX" tab in MMTTY Setup.  Select two
unused buttons. Name them RY and FOX. Paste these files in them.

On push and MMTTY will transmit RY forever until you hit TXOFF. The same
for FOX.

Hey all, I picked one of these up recently and it needs a little love. Would anyone know the name or part # of the power switch as well as the power plug? I might have a cord that'll fit but it looks unusual for a 12v connection.

Last but not least, anyone have a sample circuit to adapt the keying output to loop? Manual says not to switch high voltage directly. I guess a simple optocoupler?

Jeff

Can?t help you on the power switch but the power connector is a Philmore 8464 2 pin ac/dc plug for old ranger,Royce,Robyn, midland CB?s.  The jack is a CBJ2B.  I picked up one couple of years ago from a fellow HAM that was clearing out his garage.  Had to recap the whole thing as several had leaked and came close to damaging the pcb.  Did have to replace the keyboard encoder ROM IC as the keyboard was inop.  Just have to chase down a little bounce on some of the keys.  

Good luck.   Really a pleasure to see it work again.

Hello,
I?ve been trying to understand how the TWX service progressed. I have a 1949 Bell System publication on how to operate?a model 19 to send a message via TWX service?line to another teletype. In that publication, they?have a photo of a bunch of women sitting in front of a TWX switchboard that has a model 14?send/receive typing?reperforator with a bunch of wires manually moved across the switchboard to make connections with other teletypes.?But?in that same?picture,?there is a phone dial built?into?the switchboard.
I?m wondering what that?phone dial was used for in 1949?

I understand that later on, like in 1959 or 1960,?they used Dataphone, basically a dial up modem for teletypes to connect to each other?via regular voice phone lines and used audio tones in?an AFSK affair. And that later model Teletypes, like model 33 had a call control unit built in.?Basically automating teletype switching via automated switchboard using regular phone network instead of TWX network.
Was the TWX network ever automated? Or did they use the manual operator switchboards until the Dataphone service was established on regular phone lines? Were older model teletypes, 19 or 28?ever?retro fitted with a call control unit, similarly like model 33s??
Hard to put this all together what happened there.

ThanksAndy

TWX used manual switchboards until about 1959 when Dial TWX went into
operation.  Telex in Europe (and introduced into the U.S. by Western
Union) was dial up.  My belief is that this had to do with customer
expectations for billing.  In the U.S. long distance phone calls and
TWX calls generated bills showing the date and time of day, the number
called, the location of that number, and the duration of the call and
how much was charged for it.  Switchboard operators used the Calculagraph
clock to measure the time duration of calls.  This was printed on toll
tickets, which then were manually processed by the people who handled
billing.

Telex in Europe and perhaps long distance telephony there too used a
simpler method.  When a call was connected a counter associated with the
caller's line was connected to a pulse generator.  The pulse rate
depended somewhat on the distance called.  The customer bill showed
just the number of pulses that had been accumulated during the billing
period.  This was all easily done by standard telephone switching
equipment.

The Bell System started what was once called fully automatic customer
dialing about 1949.  Where it was available the caller could dial his
own long distance calls.  Equipment would record the calling and called
numbers and the starting and stopping time of the calls on punched paper
tape.  Then a data processing machine built of relays could read the
tapes and sort the data into individual call records that could be handled
just like switchboard operators' toll tickets.  It took until about 1959
for the entire Bell System and the independent companies to get 
substantially all customer telephones' toll charging working this way.

Now manual TWX had used a variety of transmission mechanisms.  Narrow
bandwidth telegraph circuits in places, voice frequecy carrier channels
over voice-grade circuits, concentrators that shared a number of
circuits among a larger number of customers.  With customer dialing
of toll calls in place the company decided the voice switched network
could also be used for TWX and other switched data services.  And
customers were also doing it themselves by using acoustic-coupler
modems with voice telephones.

TWX remained a data-only service, but TWX machines had to have an earphone
or a speaker so the callers could hear dial tone and other tones and voice
announcements.  DataPhone had the assumption that callers and callees
would converse by voice before switching to data transmission, so its
terminals included telephones.  Other services were proposed but not
implemented.

In that connection, the low-speed TWX and DataPhone modems were full
duplex and FSK. So there were two different frequency pairs that could
be chosen for the calling station to transmit on.  And for each of those
there was an option whether the higher or lower tone would be mark or
space.  Thus by strapping options in the modem there were eight different
mutually incompatible combinations that could be used for different 
services and charged for at different rates, should the company and the
FCC agree that they were needed..

I have one of the 6850?s as well. It was one of the first things I bought after I bought my first non-boatanchor receiver, the yaesu FR-101D (IIRC). I haven?t fired it up in ages. A cool little unit. At one point I considered installing it in my land rover to use as my RTTY terminal. Just for the nostalgia of it.

Can?t help you on the power switch but the power connector is a Philmore 8464 2 pin ac/dc plug for old ranger,Royce,Robyn, midland CB?s.  The jack is a CBJ2B.  I picked up one couple of years ago from a fellow HAM that was clearing out his garage.  Had to recap the whole thing as several had leaked and came close to damaging the pcb.  Did have to replace the keyboard encoder ROM IC as the keyboard was inop.  Just have to chase down a little bounce on some of the keys.

Good luck.   Really a pleasure to see it work again.

I like the idea of installing it in the Rover.? I have a CJ8 that I have 
thought about putting mine in, unless I can come up with a MITE.? I have 
a PRC-47 that if I can find the CV-2455 ( or replicate it as I have only 
seen one available and missed out on it)? would like to install it in 
the back of the Scrambler with a full soft top on it.

I kinda hate to bring this up but,? I have shipped numerous items out 
with the promise of repayment of mailing costs.? Some of these accounts 
are over 1 month old.? If i shipped you something and you agreed to 
repay me for the postage, please do so.? Otherwise your credit score 
goes to ZERO (0).? You know who you are.? Until these accounts are taken 
care of i will no longer honor any requests for material i have on hand 
that relates to Greenkeys.? I am unable to support everyone even though 
the gummit expects me to.

Hi Jim
Thanks for the extensive write up. Sounds like they didn?t know what method to use to gang all these machines together with the technology they had at the time. You?re right, I?m sure customer billing by the phone company?played a big role in driving what was adopted.
I guess I thought, by 1949 they would?ve used a phone to dial another user. But I guess, if people were just sending a text message to each other, without a computer, manual switchboard was the only way to connect two teletype users.?
I read about the subscription sets they had to connect two machines with the same customer. Like if they had one machine at their factory and another one at their warehouse across town. The subscription sets would directly connect both those machines together over the TWX line but to no one else.
I still somehow believe that the Dataphone or call control?approach?could be used as an alternative to the internet. But with voice and data lines so intertwined now on an IP network, it may not matter.?
I guess keeping my model 19 hooked up to internet on line 1 and my radios on line 2, will be it for now.?

TWX used manual switchboards until about 1959 when Dial TWX went into
operation.? Telex in Europe (and introduced into the U.S. by Western
Union) was dial up.? My belief is that this had to do with customer
expectations for billing.? In the U.S. long distance phone calls and
TWX calls generated bills showing the date and time of day, the number
called, the location of that number, and the duration of the call and
how much was charged for it.? Switchboard operators used the Calculagraph
clock to measure the time duration of calls.? This was printed on toll
tickets, which then were manually processed by the people who handled
billing.

Telex in Europe and perhaps long distance telephony there too used a
simpler method.? When a call was connected a counter associated with the
caller's line was connected to a pulse generator.? The pulse rate
depended somewhat on the distance called.? The customer bill showed
just the number of pulses that had been accumulated during the billing
period.? This was all easily done by standard telephone switching
equipment.

The Bell System started what was once called fully automatic customer
dialing about 1949.? Where it was available the caller could dial his
own long distance calls.? Equipment would record the calling and called
numbers and the starting and stopping time of the calls on punched paper
tape.? Then a data processing machine built of relays could read the
tapes and sort the data into individual call records that could be handled
just like switchboard operators' toll tickets.? It took until about 1959
for the entire Bell System and the independent companies to get 
substantially all customer telephones' toll charging working this way.

Now manual TWX had used a variety of transmission mechanisms.? Narrow
bandwidth telegraph circuits in places, voice frequecy carrier channels
over voice-grade circuits, concentrators that shared a number of
circuits among a larger number of customers.? With customer dialing
of toll calls in place the company decided the voice switched network
could also be used for TWX and other switched data services.? And
customers were also doing it themselves by using acoustic-coupler
modems with voice telephones.

TWX remained a data-only service, but TWX machines had to have an earphone
or a speaker so the callers could hear dial tone and other tones and voice
announcements.? DataPhone had the assumption that callers and callees
would converse by voice before switching to data transmission, so its
terminals included telephones.? Other services were proposed but not
implemented.

In that connection, the low-speed TWX and DataPhone modems were full
duplex and FSK. So there were two different frequency pairs that could
be chosen for the calling station to transmit on.? And for each of those
there was an option whether the higher or lower tone would be mark or
space.? Thus by strapping options in the modem there were eight different
mutually incompatible combinations that could be used for different 
services and charged for at different rates, should the company and the
FCC agree that they were needed..

Yes.  Different purpose.  Decades ago a large electric utility I worked for could send data to interruptable customers for electrical load management using FSK on a 50KW AM station.  As I recall it was +/- 10 Hz.  Had to be that narrow to stay within the frequency limits of an AM broadcast station.

The shift was +/- 18 Hz to stay within the FCC requirements that the
carrier frequency be within +/- 20 Hz of the assigned frequency.  The
baud rate was 75 and the demodulator was said to be one designed for
85HZ shift.

A very interesting thought- is there any chance this was done with WLW 
at 500KW during WW2?? I think the last full power transmission was 
during the war for Pres. Roosevelt to address the Germans. I know he 
intervened with the FCC to keep the 500KW transmissions going after the 
"experimental" period.

Makes you wonder if there's recordings of these transmissions - I guess
being back in that day with interference and all, a small hz difference
probably wasn't even noticeable to anyone.

?
At least one person spotted it. A local Cincinnati ham told me long ago that he somehow noticed the WLW carrier frequency was changing very slightly - maybe 10 cycles. So he called the station engineer. The engineer denied everything of course. This probably was in the 60s. Never heard anything connecting this to WLW?s super power days though.

Message-ID: <CAPK6WseV=dT5U86nPQeUsiySN553khify_9Y_4G--8X2HVN1kA@mail.gmail.com>

Just figured I'd throw it out there - does anyone know of other museum
ships doing real RTTY using real Teletype gear?

I know of the Iowa/Dan, but figured I'd ask if there's others? I talked to
Paul (Mr Rtty) today and he mentioned supplying parts to some other ships.

hard to be sure that one was really hearing it... or that it wasn't a

as a youngster i was at swampscott mass ham fest and attended a discussion of that very system over a  dinner meeting.  the person presenting was herbert hoover jr. he brought an entire re-rolled tty paper printed (error free) with quick brown fox repeated continuously. sent over i think it was wabc.  
i'll guess the transmission rate was 1 baud.

In the 1980s, the FCC authorized data transmission by AM stations. Prior
to that, in 1967, use of subaudible tones on AM was proposed for
transmitter telemetry (
http://hallikainen.com/nab/unattended/RegHistory.pdf#page=16 ). This was
finally accepted in 1969 (
http://hallikainen.com/nab/unattended/RegHistory.pdf#page=17 ). By the
way, those links are from a book I wrote for the National Association of
Broadcasters many years ago.

By the 1980s, the FCC largely got out of defining modulation methods and,
instead, just required a station stay within a specified spectral mask. A
method of transmitting data through phase modulation of the AM carrier is
described at
https://worldradiohistory.com/Archive-NAB-Publications/NAB-Radio-Subcarrier-Services-%201983.pdf#page=15
.

All of this is a form of "data broadcasting." The FCC specifically
authorized facsimile broadcast by AM stations using a subcarrier above 20
kHz. See section 3.318 at
https://hallikainen.org/org/FCC/FccRules/1955/rules19551104.pdf#page=61 .

And, as I recall reading, there were "newspapers of the air" delivering
fax over AM broadcast stations.

Annual Armed Forces Day Crossband Test

The US Department of Defense (DoD) will host this year's Armed Forces Day
(AFD) Crossband Test on May 13, 2023. This annual event is open to all
licensed amateur radio operators and will not impact any public or private
communications. For more than 50 years, military and amateur stations have
taken part in this event.

The AFD Crossband Test is a unique opportunity to test two-way
communications between military communicators and radio stations in the
Amateur Radio Service (ARS), as authorized in 47 CFR 97.111. These tests
provide opportunities and challenges for radio operators to demonstrate
individual technical skills in a tightly controlled exercise scenario.

Military stations will transmit on selected frequencies and will announce
the specific ARS frequencies monitored. All of the times are Zulu (Z), and
all frequencies are Upper Side Band (USB) unless otherwise noted. The
frequencies used for the test will not stray outside the confines of the
exercise.

A complete list of frequencies, time periods, QSL cards, and other
information can be found at:

https://www.dodmars.org/mars-comex-information-website/armed-forces-day
<https://www.dodmars.org/mars-comex-information-website/armed-forces-day>

AFD is a time of honor. It will be celebrated on Saturday, May 20, 2023.
The first AFD was celebrated with parades, open houses, receptions, and air
shows. Today, many events and activities take place and may include
multi-service military displays in areas open to the public, various
educational activities that teach children about the armed forces, and
large parades with local celebrations.
The longest running AFD parade in the United States is held in Chattanooga,
Tennessee. Certain types of music will be played at AFD 2023 events to show
respect to those in the armed forces who died for their country.

Thanks, Nick and Bob. I didn?t see any mention of shift or tones. I checked out the google drive folder too, but nothing as mundane as RTTY details. Anyone know what to expect? I would LOOOOOOVVVE to work a military station using 850 shift!

Here's the full file - you couldn't see the last 2 pages on a mobile. It
does mention 850 shift on page 3.

I don?t think they do two way RTTY/RATT.  I believe the messages out will be sent via RATT at 850hz (I can?t remember from last year of its 60 or 100wpm). 

NEPM on the list is the battleship Iowa and they will be broadcasting the SecDef message via RATT.

I've been trying to adjust the rangefinder on my 33 and I've found that it's extremely finicky.

Rangefinder settings that give me almost reliable text reception give me only 50% reliability on control characters, and if I tune it to reliably receive LF, I get about 5% misreceived text.  It seems to work better at typing speed than at full speed with paper tape, so context seems to matter.

So, I looked at the current through the selector magnet on the face of a scope.  The current rises to full current in about 1/2 of a bit time.  That seems awfully slow.  I measured the current by hooking the scope across R5, but perhaps I should have used R7?  With reference to Teletype schematic 181821 dated 4-28-67 (that one seems to describe the board I have in my CCU).

It is sort of interesting that you can see the selector armature closing on the waveform as the current rises to about 4/5 of the peak current.  The moving selector armature induces a counter EMF that stops the current rise until the armature move is done.

Also, the waveform across R5 shows instant turnoff because the decay current in the selector magnet is shunted elsewhere (via CR3, C1 and R9) so it doesn't show up.  Had I used R7 to take my measurements, I'd have seen the decay current.

Any hypotheses about what would slow the current rise that much (and possibly the current fall?)

          Doug

PS:  the fact that the local-mode loop is entirely floating with respect to ground lets you do evil things with a scope probe, grounding any part of the circuit.  If it were not a floating loop, I'd have to use a two-channel scope in differential mode.

Probably stuff you already checked, but is the 20 volt supply solid or 
does it bounce (real technical term) with the loop keyed?? I'd expect it 
to be pretty solid with a 1,500 mfd filter.?? And is the current 500 mA 
in the mark condition?? (what is the actual value of the resistor used 
to measure current, is it exactly what the schematic says?)

It has always amazed me that Teletype can manage to add little tweaks to 
a fairly simple circuit, I assume to optimize performance.? And then 
draw them up in an incomprehensible manner.

In the back of my mind I'm thinking someone has reported he had to 
replace that cap?

Message-ID: <CAGzJkdxn3AbJszChnA9eaoLh5MO8E2C6DFTPKTrzYP6v0fXnJw@mail.gmail.com>

I feel very lucky to have a working MITE and even more to have a 60cycle
unit thanks to a GreenKeys lead.  My ultimate goal is to have it mated up
to my PRC-47 and operating in the field, I still need to find the CV-2455
converter to complete the project, I'm currently running it from the
GRC-106/MD-522 combination.

  I have read(not official) on two occasions that there is a 28V version of
the MITE, the manual states availability of two AC motors 60 or 400 cycle,
it makes no mention of a DC version, the manual is dated 4/1966.

I would like to ask if any one has actual hands on experience or
documentation or pictures of a 28V MITE.  I also would like to thank all of
you for making this list a great resource for all things Green Keys.

I have got MITEs in all versions in my collection.

115V 400HZ, 28V DC and also a prototype version 220V AC 50Hz intended
to sell to German Army (Bundeswehr),
but it never came to a contract.

I have to correct. The prototype version is 115V BUT 50 Hz.

I suspect the synchronous motors of the AC-variants MITEs have rotors 
with a combination of permanent magnet excitation and a self-exciting 
ferrite ring to minimize the risk of "tipping".

The outer part of the rotor in a Mite motor is hard steel. The motor is 
capacitor start and run two pole, and is wound to bring everything close 
to saturation. It starts as an induction motor, and as it approaches 
synchronism the rotor becomes magnetized and locks in to synchronous 
speed. Motors of this design run hot and are of poor efficiency.

What kind of motor is the DC 28 Volt variant in a MITE ??? I've got one 
of this DC MITEs and two AC 115 Volts / 400Hz machines...

W7TTY ITTY news-terminal with (my) mighty 400Hz MITE

https://www.youtube.com/watch?v=MRAT6ZITwhs

At that time I was still using a programmable standard inverter with no 
output filter but a powerful EMI (RFI) noise floor !!!
And that on a shortwave field day :-(
But it was easy to change the (RX)? line speed with the inverter. :-)

Have Fun !!!
Olaf

In July 1944, if you needed to set up teletype facilities in some place you
had recently invaded, here's a helpful book -

I printed page 4 and hung it up above my desk at work. Scaled it up 140% so

Jeff,

If you are referring to the destruction of equipment to prevent the 
enemy from using it, that was/is standard on all military communications 
equipment.

I like it.  I note that the Russians have been particularly bad at that in Ukraine.  After the Ukrainians disable a Russian tank, one of their first priorities seems to have been salvage.  I've seen numerous photos of Ukrainian techs pulling spare parts from disabled Russian tanks.  It helps that Russia is invading with the same make and model Ukraine is using.

Message-ID: <CAE1er57uskdt4Ve+FPWExjzadGHzq4zXGmYDCy_ssP5o_SXRvg@mail.gmail.com>

Hi everyone. I received a spare set of parts for my model 14 (thanks Jim!)
and I recognize everything but the component in the attached picture.

It has 3 magnets, and runs to an expanded terminal block with a beautiful
plug interface (parts are labelled as part of a pluggable system).

Is this an option of some sort for paper handling perhaps?

Thank you for any help as always!

We had a discussion not too long about about the BRPE.  I was watching an old computing history video about the 1963 Sperry Rand Univac Fastrand Magnetic Drum and there was a photo of the Univac 418. Isn?t that a BRPE I see in there?

The rightmost thing sticking out of the end of the machine does look like the face of a BRPE.  The high-speed paper-tape reader to the left of it is not a Teletype product.  It looks a bit like a Digitronics reader, but I'm not sure.

Hi Eric,

You say for a 14, but is it 14 TD or reperf?  The part to the left appears to be part of  the selector mechanism of a reperf.  However, the multi-pin Jones plug was more common with a 14TD or FRXD.   

A reperf may have the jones plug if you have a lot of pull bar operate switches.  This was common on the reperf part of the FRXD.

I can't say the mechanical parts look familiar.

John, W9DDD

Seems likely.  In automatic switching systems it was necessary to feed out
blank tape at the end of a message so the end of the message could get
through the associated tape reader.  Until the advent of FRXD with its
crawling-head reader that could read the last character punched.

There was an acronym MNILFO for Measured Non-Interfering Letters Feed
Out.  Meaning it would feed out a definite amount of tape to bridge
the gap between punch and reader, non-interfering meaning that if new
traffic came into the reperf it would stop the feed out, and letters
meaning that the LTRS character was what was punched in the tape being
fed out.

https://mxtoolbox.com/SuperTool.aspx?action=mx%3ateletype.net&run=toolpage
says the domain IP address is listed on UCEPROTECTL3 which is described
as:

If you are on the UCEPROTECTL2/L3, you have an IP address from your ISP
that falls into a poor reputation range (i.e., the entire range of IP
addresses is blocked as a result of the provider hosting spammers).

Uceprotectl3 Reports Subnets
Subnet-based Blacklists are used to reject email from entire ranges of IP
Addresses, i.e. providers that are hosting companies sending spam, as well
as single IP Addresses that may fall in that range of IP Address.

Uceprotectl3 Reports Shared Hosts
Host-reputation Blacklists will list either single IP Addresses that host
multiple domains or entire ranges of IP Addresses from DNS &/or Email
Hosts that host email for their registered domains on shared email
servers. When one company sends Spam Mail or Unsolicited Bulk Email (UBE),
the entire ranges can be reported as blacklisted.

Uceprotectl3 Reports Sources Of Spam
Spam-based Blacklists are those that will list either single IP Addresses
or entire ranges that have actually received Spam, i.e. Unsolicited Bulk
Email (UBE) in their Spamtraps from an IP-Address. This could be a result
of a compromised email account, an Open Relay, or simply sending mass
emails / marketing and not following best practices according to the
"CAN-SPAM Act of 2003" (ref:
https://en.wikipedia.org/wiki/CAN-SPAM_Act_of_2003)

Uceprotectl3 Automatically Delists Entries
This blacklist does not offer any form of manual request to delist. Your
IP Address will either automatically expire from listing after a given
timeframe, or after time expires from the last receipt of spam into their
spamtraps from your IP Address.

Uceprotectl3 Accepts Payments Or Donations
This blacklist does support a manual request to remove, delist, or
expedite your IP Address from their database upon Payment or Donation of
fees to their organization. Please note the following; 1) MxToolBox does
not in any way advocate the paying of removal from any blacklists. 2)
Removal requests that are submitted without addressing the core problem
will likely result in your IP Address being relisted in the database which
can cause subsequent problems and extended listing periods without
release.

More information about UCEPROTECTL3 can be found at their website:
http://www.uceprotect.net

Reason for listing - Your ISP DIGITALOCEAN-ASN, US/AS14061 is
UCEPROTECT-Level3 listed because of a spamscore of 224.4. See:
http://www.uceprotect.net/rblcheck.php?ipr=138.68.194.30

So, it's a "bad neighborhood" or "guilt by association" issue that is
difficult to resolve.

Strip printing reperf. I do not see any similar component inside my 14 FPR.
Between the wiring and the extra components, I think this must be some
option.


https://youtu.be/pJ6UgLDMCbk

Latest behaviour, I think the code bars need some oiling, but even with all
held (this is a holding magnet selector) it is still running open, just
with the bell ringing.

What mechanism prevents printing if all bars are held? Am I maybe hitting
the out of paper bell?

Thanks,

-Eric

It should not run open with the selector magnet armature held against the
magnet core. I don't know the names of the parts, but when the armature is
held against the core, a "catch" should catch a rotating part when it gets
back to where a character starts. The range finder moves the "catch"
around the shaft to change the position of the shaft starting point when
the selector magnet is released at the beginning of the start bit. On a
model 15, I remember seeing an adjustment screw near the range finder that
appears to determine how far out the armature has to swing before the
shaft is released. So, it MIGHT be this adjustment screw. In any case,
holding the armature to the magnet SHOULD stop the machine from running
open.

Good luck!

That is it! Thanks!

I have attached 2 photos. One shows the stop pawl and the piece it stops
(hence the name) on the print shaft, and the other the piece the pawl stops
where you can see indication of I think a break.

Because the stop pawl is not being caught, the FPR runs open.

I also compared motion on my type bars mech to the one I got from Jim and
it is a world of difference. I will need to swap the printer, the mate on
the code bars at the top of the FPR looks very straightforward.

I figured out the bell meant no paper. I resolved that, but it still seems
to run "open" (I am used to my 33) even when all code bars are set. Either
that, or it is running closed, and when the selector magnets are being
held, it is erroneously not attempting to punch, or print.

Any ideas appreciated! Now that I know what it looks like to set the code
bars, I am going to try re-reading the manual a bit.

Thanks Jim! I have isolated the running open issue to the stop arm on the
main shaft being broken.

I do not suppose anyone has a replacement? I need to read the schematics
and find a part number.

Subject: [GreenKeys] Sears Mod 33
Message-ID: <178d38bd-7fde-e325-dc4b-c7be6af26167@Gmail.com>

At our Sears mail order place they had a Model 33 with a Magtape 
machine.? Orders would come in at the end of the day and the operator 
would sit at the 33 and type all the info onto tape and then run the 
tape feeding the info into the mag tape unit.? Then the main office 
would call in and read the data off the mag tape unit.? My boss got a 
call one day asking for some help as it wasn't a telco circuit or 
machine so he sent me over to investigate it.? The machine would just 
sit there and all of a sudden the platen or print ball, don't remember 
which it was would jump, not do anything else.? Every few minutes it 
would do the same thing.? In desperation i asked for an extension cord 
and plugged it into another wall circuit and the machine started working 
normally.? No idea what was on that 115vac circuit but all of a sudden 
it just started doing that and Sears operator had no idea what was going 
on.? Strange things.? They just left it plugged into the extension cord 
and a different wall plug till they quit doing business in town.

This was back in the late 70's in a two horse town.

Sources: NAVSHIPS 93434(A) and TM11-487A-3
 - doesn't mean they actually exist beyond prototypes but there was
indeed a DC motor and p/s nomenclature assigned.

Option for the AN/TGC-14(V) MITE -
DC Power Supply Kit, MK-540/UG (DC Motor PD-85U is p/o MK-540/UG, 26 vdc)

MK-540/UG POWER SUPPLY KIT, DC
To provide means of introducing primary DC power and signal
information into EQUIP, signal line power, necessary power for
converting neutral TTY signals into polar signals, and provides for
low temperature operation. It also provides motive power for TTY by
means of SER governed Motor, DC PD-85/U. Input power: 26 vdc. Output
power: Dual range line sensor is 28 vdc at 100 ma plus 6.0 vac at 450
ma; signal line power supply is 28 vdc at 100 ma. MK-540/UG is p/o TTY
Set AN/TGC-14(V) and others. It is u/w, but not p/o TTY TT-297/UG.
(USMC)

The airborne version  -
TT-264/AG says - AC power: 110/220v, 400 cps, 3 ph; DC power: 28v, 9.5 amps.
(Alternate power requirements can be met depending on how EQUIP is. ordered.)
(it is not clear to me that means either AC or DC - But if an AC motor
why would you need 9.5A at 28vdc? The specs for the AC versions say
270W total)
However -  MIL-T-22143 only says 110v, 400 cps, 1 ph.

Thank you for the information Nick, I ran the kit as an NSN and FSN,
nothing available that I can find, that will be a tough one for sure.

Found this cute (but a bit worn looking) pocket knife / money clip while brousing.  Nice big T with a square wave logo on it.
--- www.ebay.com/itm/195722952286

I don't need one, nor do I know anything about the seller.  Whoever it is, they seem to specialize in really random crap.

Last week, I mentioned problems I was having with rangefinder adjustment on my model 33.

I spent most of the day today in the retrocomputer lab, and made some progress:

a) The current through the selector magnet was low; I had to turn the trimmer in the CCU all the way to one end to get the current up to 0.5 A.

b) The tension on the selector magnet armature spring was about 2oz, but the spec says 3 to 3.5oz.  So, I tightened that.

Net result, it works a little better, but still flakey.  The selector armature is definitely not broken.

I have an Aydin demodulator model 380.
Can't find anything on a google search.
I have a think manual, may as well be Greek, very complicated.
The previous owner said this was used to copy messages from North Korea.

It seems that the input is an IF signal (0.1 - 1 volt), rather than an audio signal.
Is that correct ?
Anybody used this demodulator ?

Thanks, Fred

Have you looked at the selector magnet driver board? Theyre usually crispy critters and might need some resoldering.

Also assuming your just using local loop from keyboard/tape - have you tried with any external sources?

Subject: [GreenKeys] 60wpm FSK on AM broadcast stations - followup
Message-ID: <CAB55hNcEbHWKmhoZRoYrzfBNS6x4XBmG=xBfgcWmp-PVN4ZGMw@mail.gmail.com>

There was a previous link to a USAF project report on 100wpm
experiments in 1965 using +/-18 Hz FSK on AM broadcast stations.
That led me to find out a little more on the previous projects - I
still have no info on Projects SEACOM and RESTORE, but FWIW here is
some info on 1962 BRECOM
===============
Broadcasting Magazine October 15, 1962

The clear channel stations have been participating in emergency
communications tests with civilian defense and military officials.
Successful demonstrations have shown that point-to-point telegraph
communications can be accomplished by multiplexing the AM carrier.
This has been done successfully in three projects sponsored by the
Department of Defense: "Restore," "Brecom" and "Seacom." All of these
involve the use of clear channel stations to establish teletype
communications links, in one case from SAC headquarters in Omaha to
the east coast, and in another from San Francisco to a radar picket
plane several hundred miles offshore.
================
Congressional Record 10/11/62

DEPARTMENT OF THE AIR FORCE,
Washington, October 4, 1962.
Hon. STUART SYMINGTON, U.S. Senate.
DEAR SENATOR SYMINGTON:
We have attached the r?sum? of the Brecom project which you requested
in your letter of September 27. We hope this information will be
useful. If you need further facts, please call on us.
Sincerely,
PERRY M. Hoisington II,
Major General, U.S. Air Force, Director, Legislative Liaison.
BRECOM
WHAT IS IT?
The Broadcast Radio Emergency Communications (Brecom) system provides
teletype communications between high-level military command
headquarters. It does so through use of commercial radio broadcasting
stations without interruption to or interference with regularly
scheduled commercial broadcasts.
WHAT IS ITS PURPOSE?
An enemy using nuclear weapons could disrupt essential military
communications circuits. Therefore, the military must exploit every
means of communicating which may survive. Brecom is one of these means
which increases the probability of survival of vital military command
and control capability. This capability is provided at a very nominal
cost to the Government.
HOW DOES IT WORK?
Brecom is a 60 -word -per -minute teletype circuit between Strategic
Air Command, Offutt AFB, and the Joint Communications Agency at Fort
Ritchie, Md. The circuit is capable of transmission in both
directions, but not simultaneously. To provide additional reliability
and survivability there are alternate routes which can be utilized.
The circuits operate 24 hours daily, 7 days a week. Clear -channel
broadcasting stations are utilized for Brecom because the signals
emitted are sufficiently powerful and interference free to be reliably
received 24 hours a day at adjacent stations a hundred or more miles
away. It is this capability of the clear channel broadcasting stations
which makes Brecom possible. At nighttime, when radio signals travel
much farther, it is possible to operate the path between Offutt Air
Force Base and Fort Ritchie with fewer relays (therefore, more
reliability) than are required during the daytime. Additional power
would provide this same advantage during the daytime. Because
electrical storms cause severe disturbance at broadcast frequencies,
maximum flexibility possible is being engineered into Brecom to
provide routes around stations affected by such interference. The
attachment shows the configuration of Brecom as being tested September
3, 1962 - October 15, 1962. Other configurations are possible and will
be tested.
OTHER COMMENT
Brecom is still in the testing stage. Results thus far indicate that
Brecom is feasible and will provide a highly desirable emergency path
for military communications. Subsequent to further technical
improvement it is intended to include a cryptographic capability
allowing transmission of classified information.
WHAT IS STATUS?
The first Brecom test was conducted from April 16, 1962 -May 15, 1962.
The test revealed several shortcomings, particularly in equipment and
operating procedures. These were remedied. The second Brecom test is
being conducted during the period September 3, 1962 -October 15, 1962.
Regardless of testing status of Brecom and future improvement actions,
Brecom is currently an available and usable system and would be
utilized in any emergency, if required.
BRECOM EAST TO WEST ROUTE
Normal route:
Joint Communications Agency (JCA)-KDKA, Pittsburgh-WJR, Detroit-WGN,
Chicago-WHO, Des Moines-Strategic Air Command Headquarters (SAC) .
(Path can be reversed.)
Alternate nighttime routes:
JCA-KDKA,Plttsburgh-WSM, Nashville-SAC;
or, JCA-WWL,New Orleans-SAC.

BRECOM WEST TO EAST ROUTE
Normal route:
SAC-WOW, Omaha-WHO, Des Moines-KMOX, St. Louis-WHAS, Louisville-WLW,
Cincinnati-KDKA, Pittsburgh-JCA. (Path can be reversed.)
Alternate nighttime routes:
SAC-WOW, Omaha-WHO, Des Moines-JCA;
or, SAC-WWL-New Orleans-JCA.

I recently acquired a Teletype Model 33 ASR as an estate sale, hoping to

this located in central Minnesota who could offer some guidance to a rookie
or share their restoration do's/don'ts?

Hi,

Where in MN are you? We have an ASR-33 here in Duluth in a state of partial
restoration and disassembly that we will eventually attach to our PDP-12 (
https://umdpdp12.blogspot.com/). However, we are also in need of a local
mentor. If you find one, let us know! And if you're nearby, feel free to
come see ours -- and the PDP-12 -- maybe we can put our heads together, and
swap retrocomputing stories.

Best,

Peter

I guess possibly the most important thing is to replace the rubber cover for
the hammer. If that disintegrates it will smash the typewheel quite quickly,
as I understand it. Someone on this list has manufactured new ones so make
sure you get one.

100% replace the rubber. If you can?t get a proper rubber dot of the right type clear tubing, I believe 5/8 inch diameter for memory slid over the bar works pretty well. That is what I am currently using on the three that I have restored.
