I did another presentation on heavy metal RTTY yesterday. This one
includes more information on the DSP TU project (
https://w6iwi.org/rtty/DspTU2/ ). The Power Point is at
https://w6iwi.org/rtty/Heavy%20Metal%20RTTY241030.pptx .

Thanks to those whose content I used (such as the model 15 slow motion
video).

Message-ID: <9656493A-CBD9-4AC7-9D07-D83A26C8CC99@gmail.com>

For anyone interested in a project, I have 4 Flexowriters available as a lot for the princely sum of zero dollars. Two of these came from Jim Haynes roughly 10 years ago and I?d like to pass on that favor; he dabbled with them and got things loosened up. I also played around and made some progress but they are not turn-key. To add to the pot, I have two additional Flexo?s I?ll throw in that I was playing with before picking up Jim?s. At least one of these will read from paper tape and type, but all 4 are projects or could serve as parts. Service info is included.

I?m parting with them to clear up some space, after managing to acquire two working models in the past few years. If anyone is interested, email me. The Fridens are located in northeast Iowa.  Best- Cory

Nick,

Thanks for the MITE annual report & history!

It is interesting that this Feb 1967 report says that they were still 
making the "basic" MITE teletypewriters (AN/TGC -14, -41, TT-299, 
etc.).? I was in the US Army Signal Corps Teletypewriter Repair School 
at Ft. Gordon, GA in November, 1966, and we were told that MITE had 
stopped making these teletypewriters and parts were getting hard to get. 
They told us that the Army was using them in Armored Personnel Carriers.

In 1966, the basic Signal Corps course was 19 weeks and covered the 
Teletype Corp M14, 15, & 19 (which were being phased out) and the newer 
Kleinschmidt TT-4, -76, -98 and FGC-25. I was in the Army
Security Agency and we also had an additional 9 week course that covered 
the M28 and the MITE AN/TGC-14. In four years in the Army, I never saw a 
MITE again.? We had a few M28 KSRs in radioteletype monitor positions, 
probably because of the easy of changing the typebox for different 
alphabets (ie Cyrillic).

Have fun,

Very nice! A few years ago, I visited the NCAR Supercomputer Center in
Wyoming ( https://www.cisl.ucar.edu/capabilities/supercomputing ). Things
have changed!

By the way, I noticed some data tape machines in the photos. Not shown
were disk drives with removable disk cartridges. There's a cartridge
available at a surplus store here in Tucson in case anyone wants one.

I always wonder about the designer of the MITE, Bernard Howard.  He got
all the patents on the MITE machine.  The only biography of him is in
Western Union Tehnical Review, July 1958, where it shows him bouncing
the military/aerospace industry, and then he disappears.

Hi all:
 
It's time for the biannual Veteran's/Memorial day list.
 
I see we have some newcomers on the list and for those unfamiliar with it, I will quote from it.

 This list was started by George W7TTY Hutchison a while back, and i
have been exhorted to continue the tradition which i will proudly
preserve and maintain.

This list is open to all veterans of the u.s. military service.
those who served in the merchant marine are eligible, as are those
who belonged to units whose existence are not to be discussed.

Please send your name, rank, branch, and the dates and we will
gladly add your information. 

e-mail address is - til128 at juno.com

Thanks to -all- for your service to America.

The list will be sent on Sunday the 10th on all ITTY channels at 1400 EST.

I have been trying these suggestions using curl to receive ITTY and pipe it through lame and minimodem. It works well.

 

However, I didn?t like that curl exits after every message. So, I thought I would try to write my own code that keeps going, using libcurl, which is what curl is built from.

 

I discovered though that the ITTY feed does something strange and it causes curl (and libcurl) to just silently exit at the end of a message. It never reaches my cleanup code, it just dies. I thought it was a problem with my code, but I don?t think it is, there is something specifically wrong with http://internet-tty.net:8000/ITTY that cause curl to die. I have been trying to work it out but have not found the issue yet. Is anyone aware of anything peculiar about the ITTY feed? It doesn?t seem to happen for the EUROPE feed, I am not sure yet about AUTOSTART and it is able to repeatedly download other URLs (www.example.com <http://www.example.com>  for example).

 

Thanks

 

Rob

Here are some aliases, which combine 'curl', 'lame' and 'minimodem'.   I haven't run these unattended for a while, and I seem to remember there are dropout situations that will break them easily - so you could then wrap everything in a loop if necessary.  But they might make a good starting point for you.

 


alias autostart='curl -N -s http://internet-tty.net:8030/AUTOSTART | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q -R 11025 -f -'
alias europe='curl -N -s internet-tty.net:8040/EUROPE <http://internet-tty.net:8040/EUROPE>  | lame --decode --quiet --mp3input - - | minimodem 50 -M 1275 -S 1445 -5 -i -a -q -R 11025 -f -'

I already have the means to connect my ASR33 from software running on a Raspberry PI or a PC via reverse Telnet. The bit I am missing is what software (if any) there might be that I could run on a Raspberry Pi, or Windows that runs in the background (no GUI) to decode the ITTY audio signal. I am a software developer though, so I guess if such a thing doesn't exist then perhaps I can modify the MMTTY code that is published on GitHub.

I see on the RTTY page it says "Most users have configured their mechanical
teletype machines to power up when receiving a broadcast and the power down
after the message is delivered."

 

How do people do this? I have a Model 33 ASR and I don't like to leave it
switched on for long periods.

You need a relay to bring the teletype up. It all depends on how you are
receiving the broadcast as to how to set that up.

I would not suggest having a 33 on autostart. They are not very robust
machines, and are best saved for live demos and interactive usage in my
humble opinion.

Well my idea is not to do this 24x7, but just as a demo from time to time, but still without it being powered on all the time.

You need a relay to bring the teletype up. It all depends on how you are receiving the broadcast as to how to set that up.

 

I would not suggest having a 33 on autostart. They are not very robust machines, and are best saved for live demos and interactive usage in my humble opinion.

But I guess the point is what do people use to trigger the relay? I guess if I am running my own modified version of Curl on a Raspberry Pi I could use the same code to trigger a relay.

Sure, if you are using linux there are lots of easy options. If you share
your current scripts we can take a look.

http://denkovi.com/usb-relay-board-four-channels-for-home-automation-v2

This is what I would use doing it today. Makes it nice and easy to do
everything in a single script.

Spinning a 33 up and down again for each message vs running the motor
continuously, I would love to know if there was any guidance on the 33 for
best practices.

I imagine if you only have say 30 seconds between messages, spinning up and
down does more harm than good, one hour, obviously far better to spin down,
where is the line?

My plan is to get a relay board for my Raspberry Pi, write a little bit of code that I can parameterise such that it will power on/off when there is traffic, giving the 33 time to start before sending characters and then powering down after whatever length of time makes sense. I can insert that into the pipeline of commands given to me on another thread, using curl, lame and minimodem.

 

Regards

 

Rob

Looks like curl -N should do the trick them without me having to write a special program to keep it running. I wish I had checked the other feeds before assuming curl just exits after every message!

The ITTY channels each have a footer transmission after the main transmission. Maybe the footers are different. I will look into this later today.

I have been trying these suggestions using curl to receive ITTY and pipe it through lame and minimodem. It works well.

 

However, I didn?t like that curl exits after every message. So, I thought I would try to write my own code that keeps going, using libcurl, which is what curl is built from.

 

I discovered though that the ITTY feed does something strange and it causes curl (and libcurl) to just silently exit at the end of a message. It never reaches my cleanup code, it just dies. I thought it was a problem with my code, but I don?t think it is, there is something specifically wrong with http://internet-tty.net:8000/ITTY that cause curl to die. I have been trying to work it out but have not found the issue yet. Is anyone aware of anything peculiar about the ITTY feed? It doesn?t seem to happen for the EUROPE feed, I am not sure yet about AUTOSTART and it is able to repeatedly download other URLs (www.example.com <http://www.example.com>  for example).

 

Thanks

Here are some aliases, which combine 'curl', 'lame' and 'minimodem'.   I haven't run these unattended for a while, and I seem to remember there are dropout situations that will break them easily - so you could then wrap everything in a loop if necessary.  But they might make a good starting point for you.

 


alias autostart='curl -N -s http://internet-tty.net:8030/AUTOSTART | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q -R 11025 -f -'
alias europe='curl -N -s internet-tty.net:8040/EUROPE <http://internet-tty.net:8040/EUROPE>  | lame --decode --quiet --mp3input - - | minimodem 50 -M 1275 -S 1445 -5 -i -a -q -R 11025 -f -'
alias itty='curl -N -s http://internet-tty.net:8000/ITTY | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q --rx-one -R 11025 -f -'

I am a software developer though, so I guess if such a thing doesn't exist then perhaps I can modify the MMTTY code that is published on GitHub.

I've also designed and simulated a circuit that is loop powered. It
detects traffic on the loop, then holds the SSR for about a minute. I'll
post a link when I get home from dance camp.

Rob, I have several very simple shell scripts here for running the 
different ITTY sources or printing files for RazPi.

The ITTY for US runs continuously.
Maybe see if they are of use to you.

Hello John,

I tried piping this into minimodem following the suggestions using curl that I received before, but it doesn't seem to work. This is what I tried

mpg123 http://internet-tty.net:8000/ITTY -q -s | minimodem rtty -i -a -q --rx-one -R 11025 -f -

There was no output from this command (other than some header information). Am I missing something?

Thanks

Rob

Hi Rob.
Are you attempting to decode to audio and saving with minimodem to a 
text file or just send the ITTY FSK audio to your TU for printing? My 
shells only result in audio FSK for inputting to a TU and just work. I 
have no experience with piping mpg to minimodem for saving although I 
will definitelly try when time permits. If saving to a file  you may 
need to provide a file type for saving? .txt? or remove the -f just to 
print to screen as first step. Also you might try without the "-i" as it 
may undo the -a auto mark/space detect. And try removing the -one, -R 
11025, etc., until you get the basics working. Using defaults should be 
the place to start and may be all you need. And I don't use curl at all.

73, John W1AN

Subject: [GreenKeys] Floor mount M28 RO for sale
Message-ID: <415dc2af-5673-4716-bb3e-1f2ccf1828e1@earthlink.net>

The AWA Museum has an excess M28 RO in a floor cabinet for sale.? If no 
interest here, it will be listed on Ebay / Craigs List.

The ESU looks like it was made by/for Western Union.? There is also a 
large selenium power supply in the base made by/for Western Union.? The 
cabinet has some dents/chips on the rear and the message viewing glass 
is cracked, but otherwise, in good condition. This floor mount is on 
wheels, so easy to move.

When I put power to it, the motor runs, but the printer runs closed, 
even though there is no current in the selector magnet (SM has been 
rewired with wires coming directly off the SM, bypassing the ESU).

Unit located at the AWA Museum in Bloomfield (near Rochester), NY.? 
Pick-up only, but buyer will get a free tour of the AWA Museum.

Please contact me off-line to make an offer or for more information.

Thanks & 73,

Subject: [GreenKeys] A newbie with M35B tape typing unit
Message-ID: <CALQ8JPj4S-rjzpi-_hNuF_J7WByS85GziEVd6fTSwg5L8-K76w@mail.gmail.com>

Hello list,

Been lurking here for a while. I am in Norway and recently acquired an
M35B tape typing unit with hope to repurpose it for a sort of an art
project. My experience is with embedded systems development and am an
ok machinist so hopefully I'll get it running. However there are a few
questions I would like to clear up with resident experts.

I only have the typing unit itself: neither the base nor the motor
with reduction gears. My plan is to build the base, paper tape feed
and the drive with a third party vintage motor. The input shaft has a
helical gear, and I see M28 repeforators were driven with a timing
belt instead. Would a simple V- or round belt do here?

What was the reduction rate from the motors to the input shaft? Down
to 100 rpm? 60?

What should the motor be rated for? I see there was a variety of
teletype motors anywhere from 1/12 to 1/25HP but I assume
reperforators were on the lower end?

The unit cycles manually but is tacky. Its printing head is in good
condition if dirty. What is the preferred cleaning method? My first
instinct for getting rid of congealed hydrocarbons is to dunk it into
motor wash oil but I see people use dish soap. A bit concerned for the
shellac-covered electromagnets, should one unmount these prior to
cleaning?

What do you lubricate it with? I have some Aeroshell grease for hefty
parts and some oils, from motor oil down to Moebius. Figure it's light
synthetic oil but nothing especially fancy anywhere?

This is an ASCII machine so supposedly uses 1" tape. Is there any good
source for it other than occasional eBay lots? Should I look for
unoiled tape specifically to print well?

Thanks,
  Eugene.

Kinda related in that it is ITTY and Linux, I'm trying to convert the ITTY
MP3 stream to an 8 bit 8 kHz WAV stream. So far, I'm thinking something
like

wget -O - http://internet-tty.net:8000/ITTY | lame --mp3input -m m
--resample 8 - -

Ideally this would send a stream to STDOUT which I can then send to the
web server.

Any ideas on how to do this?

Thanks!

Subject: [GreenKeys] Raspberry Pi loop interface
Message-ID: <98f1df49-ddbd-bd5d-26fa-ad0f6eafcd63@tapr.org>

A while back someone mentioned making an interface between a Pi and a 60 
mA loop. I don't recall any details being discussed at the time.

Questions

1. What I/O pins on the 40 header did you use?

2. Were you able to use any of the internal UARTs or did you do bit banging?

I ran into problems with an Arduino with it not being able to run the 
UART slow enough and I don't recall if that's a problem with the Pi.


I'm finally making a transition from an old program that originally ran 
on DOS (and eventually Windows) to KiCAD and decide this would be a 
simple enough project ro practice with.

Ive been successful with Arduino and a literal relay, look at Hackaday.

I don?t remember which pins I used, but

I bit bang them directly from python code. I figured why bother with serial io, usb dongles, etc with a speed that low. I do the same for reading the current loop. Works great, even an ancient pi2 was fast enough to do this from python.

Dear All,

I?m using intercom and I have one of those audio to 60Ma loops hooked to a
teletype model 19 (model 15) and the decoder module is not working with
Intercom. It works with the itty broadcast so I know it is not a decoder
issue. What do you recommend I adjust in intercom to fix my issue?

Thanks for the comments! The DSP TU accepts 8 kHz PCM audio, currently
from the on Chip ADC ( https://w6iwi.org/rtty/DspTU2/ ). I have a WiFi
module on the board that I want to connect to ITTY. However, decoding MP3
in the microcontrollers MAY make the DSP functions fall behind, so I'm
looking at having my web server convert the MP3 to 8 bit 8 kHz WAV and
then pass on the PCM audio. The DSP TU would request ITTY from my server
which would then request it from ITTY.

It MAY be possible to do the MP3 decoding in the microcontroller, but I'm
looking at the intermediate server as an option.

THANKS!

Hello Paul,

 

I was just wondering if you ever got to look at this issue with ITTY killing curl while the Europe channel doesn?t?

 

Thanks

?That is strange that the Europe channel is ok and the ITTY channel is not. I?d like to resolve this. 

 

The ITTY channels each have a footer transmission after the main transmission. Maybe the footers are different. I will look into this later today.

I have been trying these suggestions using curl to receive ITTY and pipe it through lame and minimodem. It works well.

 

However, I didn?t like that curl exits after every message. So, I thought I would try to write my own code that keeps going, using libcurl, which is what curl is built from.

 

I discovered though that the ITTY feed does something strange and it causes curl (and libcurl) to just silently exit at the end of a message. It never reaches my cleanup code, it just dies. I thought it was a problem with my code, but I don?t think it is, there is something specifically wrong with http://internet-tty.net:8000/ITTY that cause curl to die. I have been trying to work it out but have not found the issue yet. Is anyone aware of anything peculiar about the ITTY feed? It doesn?t seem to happen for the EUROPE feed, I am not sure yet about AUTOSTART and it is able to repeatedly download other URLs (www.example.com <http://www.example.com>  for example).

 

Thanks

 

Rob

Here are some aliases, which combine 'curl', 'lame' and 'minimodem'.   I haven't run these unattended for a while, and I seem to remember there are dropout situations that will break them easily - so you could then wrap everything in a loop if necessary.  But they might make a good starting point for you.

 


alias autostart='curl -N -s http://internet-tty.net:8030/AUTOSTART | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q -R 11025 -f -'
alias europe='curl -N -s internet-tty.net:8040/EUROPE <http://internet-tty.net:8040/EUROPE>  | lame --decode --quiet --mp3input - - | minimodem 50 -M 1275 -S 1445 -5 -i -a -q -R 11025 -f -'
alias itty='curl -N -s http://internet-tty.net:8000/ITTY | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q --rx-one -R 11025 -f -'

I already have the means to connect my ASR33 from software running on a Raspberry PI or a PC via reverse Telnet. The bit I am missing is what software (if any) there might be that I could run on a Raspberry Pi, or Windows that runs in the background (no GUI) to decode the ITTY audio signal. I am a software developer though, so I guess if such a thing doesn't exist then perhaps I can modify the MMTTY code that is published on GitHub.

Good afternoon all,

I'm hoping to connect my Model 19 Teletype to a radio transceiver for use
with RTTY. I've learned that I need a terminal unit to do this, but haven't
found a ton of information about what terminal units to look for.

What can I look for to find a terminal unit? What can I search for? Is ebay
my best bet for finding this sort of equipment?

Thank you for the help.

Go to rtty.com and look to the left under demodulators.

 

The ST-6 is a very good one.  Outside of ebay I do not know where to look for one as I doubt any new ones have been sold in 20 years.  The demodulator hooks to the speaker and the audio is filtered into 2 tones that switch loop supply of around 150 volts off and on for the printer.

That's a good resource on TU information. I have a comparison of various
terminal units at https://w6iwi.org/rtty/TuComparison/ .

Also, Free To A Good Home, I have bare boards for my DSP TU available (
see https://w6iwi.org/rtty/DspTU2/ ). Try your hand at surface mount
soldering!

There is always the opportunity to build a demodulator.. OK the torroids
would be hard to get but I remember building one using 567 tone decoders..
All on a perf board.. But that might be asking to much these days haha..

Well there you go.. I am still using my demodulator I built from the old
ARRL specialized comm handbook..Over 45 years ago.. Have it hooked to the
raspberry Pi for the IITY and
Autostart channel audio.. There needs to be more builders out there..  Skip

Hello Paul,

 

It is fair to say that I will end up using the autostart feed rather than ITTY, but my sense of tidiness tells me that I would like to understand why ITTY kills curl stone dead, and I may want to use ITTY from time to time.

 

I think it would be good to fix this if the solution is easy to find and fix because others might have similar issues in future and not understand what is going on.

 

Thanks

 

Rob

Hi Rob. I stopped looking because I thought you went another direction. I guess I was wrong about that?  

 

I?ll start looking into it.

I was just wondering if you ever got to look at this issue with ITTY killing curl while the Europe channel doesn?t?

The ITTY channels each have a footer transmission after the main transmission. Maybe the footers are different. I will look into this later today.

I have been trying these suggestions using curl to receive ITTY and pipe it through lame and minimodem. It works well.

 

However, I didn?t like that curl exits after every message. So, I thought I would try to write my own code that keeps going, using libcurl, which is what curl is built from.

 

I discovered though that the ITTY feed does something strange and it causes curl (and libcurl) to just silently exit at the end of a message. It never reaches my cleanup code, it just dies. I thought it was a problem with my code, but I don?t think it is, there is something specifically wrong with http://internet-tty.net:8000/ITTY that cause curl to die.

Here are some aliases, which combine 'curl', 'lame' and 'minimodem'.   I haven't run these unattended for a while, and I seem to remember there are dropout situations that will break them easily - so you could then wrap everything in a loop if necessary.  But they might make a good starting point for you.

 


alias autostart='curl -N -s http://internet-tty.net:8030/AUTOSTART | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q -R 11025 -f -'
alias europe='curl -N -s internet-tty.net:8040/EUROPE <http://internet-tty.net:8040/EUROPE>  | lame --decode --quiet --mp3input - - | minimodem 50 -M 1275 -S 1445 -5 -i -a -q -R 11025 -f -'

I am a software developer though, so I guess if such a thing doesn't exist then perhaps I can modify the MMTTY code that is published on GitHub.

Sometimes the mind just takes off on a tangent.

On several 14 reperfs and tape printers I'd seen there's a nice switch 
back near the selector magnets which switches the connect between series 
and parallel.

I don't recall if I've ever seen that on a 15, but it might have existed?

So why when they did the 28 ASR/KSR did they bury a terminal strip in 
the bottom of the electrical service unit, LESU, so that you have to 
tear the machine apart and flip the LESU upside down to change between 
series and parallel?

On the 28/35 typing reperf and tape printer, you change it right at the 
selector magnets, no switch, but easy to get at.

W9DDD,

I have a holding magnet 15 with a 20/60 mil switch. So they did indeed put
them on some 15s.

The only reason I could think of would be that lack of needing to switch it once it was set. Maybe they found that people would switch the easy access switches and burn out the magnets.  

Or it was the age old problem of engineering not thinking about technician at the end of the line. 

My 2 1/4 cents

The 60 ma loop comes from the DC telegraph circuits which could be miles 
long.? In the 1940-50s, when more TTYs were used with voice circuits 
(telephone modems & radios), the distance to the modem or radio 
converter (TU) was measured in feet, not miles, and a lower loop current 
could be used.

All the Kleinschmidt models (designed for the military, starting in the 
late 1940s) had easily accessible 20/60 ma switches. The switch on the 
TT-4 was labeled "DC LINE / VOICE FREQ LINE"

In the M28 line, there was typically an "Electrical Service Unit" (ESU) 
which contained a polar relay that isolated the selector magnet from the 
external line.? Since the SM was on an internal loop, it did not need to 
easily switched between 20 & 60 ma. I'm not as familiar with the M28 
line, but I think there as probably a wiring choice on the terminal 
strip on the rear wall for the 20/60 ma choice.

Have fun,

Duncan

Yes I tried that but all I could see was data arriving and then curl dying. There didn?t seem anything odd about the data, but it was all binary. I could try to delve deeper but I thought the best starting point was to ask if there is any known difference between ITTY and the other feeds. Paul seemed to think that possibly some headers might be different.

Hello Paul,

 

It is fair to say that I will end up using the autostart feed rather than ITTY, but my sense of tidiness tells me that I would like to understand why ITTY kills curl stone dead, and I may want to use ITTY from time to time.

 

I think it would be good to fix this if the solution is easy to find and fix because others might have similar issues in future and not understand what is going on.

 

Thanks

?That is strange that the Europe channel is ok and the ITTY channel is not. I?d like to resolve this. 

 

The ITTY channels each have a footer transmission after the main transmission. Maybe the footers are different. I will look into this later today.

I have been trying these suggestions using curl to receive ITTY and pipe it through lame and minimodem. It works well.

 

However, I didn?t like that curl exits after every message. So, I thought I would try to write my own code that keeps going, using libcurl, which is what curl is built from.

 

I discovered though that the ITTY feed does something strange and it causes curl (and libcurl) to just silently exit at the end of a message. It never reaches my cleanup code, it just dies. I thought it was a problem with my code, but I don?t think it is, there is something specifically wrong with http://internet-tty.net:8000/ITTY that cause curl to die. I have been trying to work it out but have not found the issue yet. Is anyone aware of anything peculiar about the ITTY feed? It doesn?t seem to happen for the EUROPE feed, I am not sure yet about AUTOSTART and it is able to repeatedly download other URLs (www.example.com <http://www.example.com>  for example).

 

Thanks

Here are some aliases, which combine 'curl', 'lame' and 'minimodem'.   I haven't run these unattended for a while, and I seem to remember there are dropout situations that will break them easily - so you could then wrap everything in a loop if necessary.  But they might make a good starting point for you.

 


alias autostart='curl -N -s http://internet-tty.net:8030/AUTOSTART | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q -R 11025 -f -'
alias europe='curl -N -s internet-tty.net:8040/EUROPE <http://internet-tty.net:8040/EUROPE>  | lame --decode --quiet --mp3input - - | minimodem 50 -M 1275 -S 1445 -5 -i -a -q -R 11025 -f -'
alias itty='curl -N -s http://internet-tty.net:8000/ITTY | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q --rx-one -R 11025 -f -'

I already have the means to connect my ASR33 from software running on a Raspberry PI or a PC via reverse Telnet. The bit I am missing is what software (if any) there might be that I could run on a Raspberry Pi, or Windows that runs in the background (no GUI) to decode the ITTY audio signal. I am a software developer though, so I guess if such a thing doesn't exist then perhaps I can modify the MMTTY code that is published on GitHub.

Re: the M28, yes has a hard to get to terminal strip accessed from the 
bottom of the LESU.   I remember the switch on the TT-76.  My GRC-46 was 
missing the TT-98 for the whole year I was assigned to it.  So I don't 
know about it. Never saw TT-4 while on active duty.  But you have 
explained what at the time seemed to be a strange way to label the switch.

W9DDD,

The TT-98 was a "deluxe" TT-4.? The TT-98 had a plug-in box in the rear 
left corner that had all the connections and a rotary switch for 60ma, 
20 ma, polar, & local test.? I worked on GRC-46s in Viet Nam.? We 
typically used TH-5 & TH-22? modems instead of the radio.

We have a cut-open AN/GRC-46 in the AWA Communication Technologies Museum.

It may be that the M28s were mainly used in fixed (or naval) 
installations and were typically set up for one type of current loop and 
rarely changed.? The Kleinschmidts, however were used in more tactical 
installations and were smaller and easier to move around, so they needed 
to be more flexible in adjusting for different current loops.

73 & have fun,

At the risk of an overly long post...the issues are how to build the
machine, and how to transmit signals to it.  If you're transmitting a
short distance, such as from a radio demodulator to a nearby machine,
you can get by with the standard 60 ma 120 V current loop. But the
machine might have been built with a holding magnet selector so that
20 ma loop is another possibility.  And the signal source might be
nearby, or might be a long wire line, or a carrier system channel,
and might be operated neutral or polar or something else.  So the
simplest circuit migh not do.  If it's one sender to a lot of receivers,
especially on a long wire circuit, polar operation is preferred.  But
it's hard to use polar if there are several senders in the net.
Or if the machine is connected to a switchboard you need to have
everying appearing on the switchboard be the same so that you can
connect any station to any other without worrying about whether
it is polar or neutral or something more exotic.  In some systems
line current is on all the time, so if you have a big installation
it is advantageous to run 20 ma loops just to save power.  Recall that
a lot of Model 15 sets in the military were not connected directly
to a line, but used that BE-77 (?) line unit between the machine and
the signal line.

I once saw a Model 15 that had a decal on the copy holder saying it
would work on 20 or 60 ma by connecting he selector magnet coils in
series or parallel.  As I recall this was a military machine.

What you would like to buy from Teletype is a machine all set up and
ready to install.  So it could come from the factory configured with
some connection of the selector coils and with or without a line relay
block in the LESU and all your installation could be done from the
back of cabinet terminal strips.  Of course as time went on the number
of possibilities increased so it was harder to make one standard universal
set for all applications.

The number of options in these machines is astounding. The model 15s I had
in high school had a fat wiring harness with wires going everywhere and a
polar relay in back. Since I run the machines half duplex (keyboard in
series with selector magnet), there's just a signal pair (60 mA) and AC
power going into the printer. I think the polar relay or whatever line
interface equipment could to in a separate line interface box that might
be a polar relay, a modem, or who knows what. But, the interface to the
machine is 2 wires with 60 mA. 60 mA instead of 20 since every machine
will work at 60 mA. But... I didn't design it.

I tried just now with ITTY and curl still dies. I may have a bit of time today and will try to look at it a bit more closely. In the meantime I think you can put the footer back.

 

If the footer is a text file though, are you encoding that into audio? If that is the case then Curl isn?t going to ?see? the CRLFs anyway. I am not quite sure how it works on the sending side.

 

Regards

 

Rob

Subject: Re: [GreenKeys] ITTY to real Teletype

 

The ITTY feeds all work the same way: send a header, send the article, and send a footer. The footer is a text file on the server.  The EUROPE server is missing the footer file, so nothing is sent. The main ITTY server has a footer with five or six CR and LF characters and that is all. The intent was to put some space between the articles. 

 

Could it be that curl shuts off if it sees a stream of multiple CRLFs?

 

For now, to help us test, I have deleted the footer.txt file on the main ITTY server. Let me know if curl now works. 

 

We can also experiment by sending an article with only CRLFs through to AUTOSTART to see if curl dies. 

 

Paul

Yes I tried that but all I could see was data arriving and then curl dying. There didn?t seem anything odd about the data, but it was all binary. I could try to delve deeper but I thought the best starting point was to ask if there is any known difference between ITTY and the other feeds. Paul seemed to think that possibly some headers might be different.

Hello Paul,

 

It is fair to say that I will end up using the autostart feed rather than ITTY, but my sense of tidiness tells me that I would like to understand why ITTY kills curl stone dead, and I may want to use ITTY from time to time.

 

I think it would be good to fix this if the solution is easy to find and fix because others might have similar issues in future and not understand what is going on.

Subject: Re: [GreenKeys] ITTY to real Teletype

 

?That is strange that the Europe channel is ok and the ITTY channel is not. I?d like to resolve this. 

 

The ITTY channels each have a footer transmission after the main transmission. Maybe the footers are different. I will look into this later today.

I have been trying these suggestions using curl to receive ITTY and pipe it through lame and minimodem. It works well.

 

However, I didn?t like that curl exits after every message. So, I thought I would try to write my own code that keeps going, using libcurl, which is what curl is built from.

 

I discovered though that the ITTY feed does something strange and it causes curl (and libcurl) to just silently exit at the end of a message. It never reaches my cleanup code, it just dies. I thought it was a problem with my code, but I don?t think it is, there is something specifically wrong with http://internet-tty.net:8000/ITTY that cause curl to die. I have been trying to work it out but have not found the issue yet. Is anyone aware of anything peculiar about the ITTY feed? It doesn?t seem to happen for the EUROPE feed, I am not sure yet about AUTOSTART and it is able to repeatedly download other URLs (www.example.com <http://www.example.com>  for example).

 

Thanks

Here are some aliases, which combine 'curl', 'lame' and 'minimodem'.   I haven't run these unattended for a while, and I seem to remember there are dropout situations that will break them easily - so you could then wrap everything in a loop if necessary.  But they might make a good starting point for you.

 


alias autostart='curl -N -s http://internet-tty.net:8030/AUTOSTART | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q -R 11025 -f -'
alias europe='curl -N -s internet-tty.net:8040/EUROPE <http://internet-tty.net:8040/EUROPE>  | lame --decode --quiet --mp3input - - | minimodem 50 -M 1275 -S 1445 -5 -i -a -q -R 11025 -f -'
alias itty='curl -N -s http://internet-tty.net:8000/ITTY | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q --rx-one -R 11025 -f -'

I already have the means to connect my ASR33 from software running on a Raspberry PI or a PC via reverse Telnet. The bit I am missing is what software (if any) there might be that I could run on a Raspberry Pi, or Windows that runs in the background (no GUI) to decode the ITTY audio signal. I am a software developer though, so I guess if such a thing doesn't exist then perhaps I can modify the MMTTY code that is published on GitHub.

On a PC I was using, I was just reading the screen, and not sending on 
to a real machine.  I was letting it run 24/7, but at times I'd come 
back into the room and find it stalled.  I don't recall if the problem 
was resolved.Unfortunately that PC is currently mothballed due to some 
renovations going on.

I don't think curl knows whats in the bit stream.  It just fetches the 
audio stream and pipes it to lame

Subject: [GreenKeys] ITTY to real Teletype

My thoughts exactly, I doubt Curl knows about the footer, but it is very odd that when a message finishes on ITTY it just dies without an error, but other feeds continue to receive other messages. Going to look at tcpdump, but my last attempt didn't show anything odd.

ITTY should act the same as my streams. At the end of an article there are
several seconds of LTRS characters, several seconds of steady mark  then
several more seconds of LTRS.

If you listen to the tones you will hear it.

Folks,

Couple of items in the shack that are surplus to requirements:

HAL RVD-1002 Visual Display System.  This thing takes in 5-bit Baudot code
from a terminal unit, and drives a television monitor to display 20 lines
of 50 characters each.  Comes with a HAL manual.  No idea if it works or
not, but it's.. interesting..?  $20 + shipping.

Teleproduct TMB-2A-7 2-character Test Message Generator.  You now know as
much as I do..:)  $10 + shipping.

Happy to supply photos to anyone who might be interested!  Shipping from
27516.

I have determined that the problem is not curl, but either lame or minimodem is crashing in the following command:

 

curl -N -s http://internet-tty.net:8000/ITTY | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q --rx-one -R 11025 -f

 

I am trying to work out which one is crashing.

I?m puzzled but will keep investigating. Later today I?ll put in a footer in that has some text. Let?s see if curl dies before or after the footer is sent. I?ll let you know when it is ready.

I tried just now with ITTY and curl still dies. I may have a bit of time today and will try to look at it a bit more closely. In the meantime I think you can put the footer back.

 

If the footer is a text file though, are you encoding that into audio? If that is the case then Curl isn?t going to ?see? the CRLFs anyway. I am not quite sure how it works on the sending side.

Subject: Re: [GreenKeys] ITTY to real Teletype

 

The ITTY feeds all work the same way: send a header, send the article, and send a footer. The footer is a text file on the server.  The EUROPE server is missing the footer file, so nothing is sent. The main ITTY server has a footer with five or six CR and LF characters and that is all. The intent was to put some space between the articles. 

 

Could it be that curl shuts off if it sees a stream of multiple CRLFs?

 

For now, to help us test, I have deleted the footer.txt file on the main ITTY server. Let me know if curl now works. 

 

We can also experiment by sending an article with only CRLFs through to AUTOSTART to see if curl dies. 

 

Paul

Yes I tried that but all I could see was data arriving and then curl dying. There didn?t seem anything odd about the data, but it was all binary. I could try to delve deeper but I thought the best starting point was to ask if there is any known difference between ITTY and the other feeds. Paul seemed to think that possibly some headers might be different.

Hello Paul,

 

It is fair to say that I will end up using the autostart feed rather than ITTY, but my sense of tidiness tells me that I would like to understand why ITTY kills curl stone dead, and I may want to use ITTY from time to time.

 

I think it would be good to fix this if the solution is easy to find and fix because others might have similar issues in future and not understand what is going on.

 

Thanks

?That is strange that the Europe channel is ok and the ITTY channel is not. I?d like to resolve this. 

 

The ITTY channels each have a footer transmission after the main transmission. Maybe the footers are different. I will look into this later today.

I have been trying these suggestions using curl to receive ITTY and pipe it through lame and minimodem. It works well.

 

However, I didn?t like that curl exits after every message. So, I thought I would try to write my own code that keeps going, using libcurl, which is what curl is built from.

 

I discovered though that the ITTY feed does something strange and it causes curl (and libcurl) to just silently exit at the end of a message. It never reaches my cleanup code, it just dies. I thought it was a problem with my code, but I don?t think it is, there is something specifically wrong with http://internet-tty.net:8000/ITTY that cause curl to die. I have been trying to work it out but have not found the issue yet. Is anyone aware of anything peculiar about the ITTY feed? It doesn?t seem to happen for the EUROPE feed, I am not sure yet about AUTOSTART and it is able to repeatedly download other URLs (www.example.com <http://www.example.com>  for example).

 

Thanks

 

Rob

Here are some aliases, which combine 'curl', 'lame' and 'minimodem'.   I haven't run these unattended for a while, and I seem to remember there are dropout situations that will break them easily - so you could then wrap everything in a loop if necessary.  But they might make a good starting point for you.

 


alias autostart='curl -N -s http://internet-tty.net:8030/AUTOSTART | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q -R 11025 -f -'
alias europe='curl -N -s internet-tty.net:8040/EUROPE <http://internet-tty.net:8040/EUROPE>  | lame --decode --quiet --mp3input - - | minimodem 50 -M 1275 -S 1445 -5 -i -a -q -R 11025 -f -'
alias itty='curl -N -s http://internet-tty.net:8000/ITTY | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q --rx-one -R 11025 -f -'

I already have the means to connect my ASR33 from software running on a Raspberry PI or a PC via reverse Telnet. The bit I am missing is what software (if any) there might be that I could run on a Raspberry Pi, or Windows that runs in the background (no GUI) to decode the ITTY audio signal. I am a software developer though, so I guess if such a thing doesn't exist then perhaps I can modify the MMTTY code that is published on GitHub.

Use just --rx 

 

 

       --rx-one

              Quit after the first carrier/no-carrier event (applies to --rx mode only)

OK, I changed the footer. It should now print ?mesage complete?

I?m puzzled but will keep investigating. Later today I?ll put in a footer in that has some text. Let?s see if curl dies before or after the footer is sent. I?ll let you know when it is ready.

I tried just now with ITTY and curl still dies. I may have a bit of time today and will try to look at it a bit more closely. In the meantime I think you can put the footer back.

 

If the footer is a text file though, are you encoding that into audio? If that is the case then Curl isn?t going to ?see? the CRLFs anyway. I am not quite sure how it works on the sending side.

Subject: Re: [GreenKeys] ITTY to real Teletype

 

The ITTY feeds all work the same way: send a header, send the article, and send a footer. The footer is a text file on the server.  The EUROPE server is missing the footer file, so nothing is sent. The main ITTY server has a footer with five or six CR and LF characters and that is all. The intent was to put some space between the articles. 

 

Could it be that curl shuts off if it sees a stream of multiple CRLFs?

 

For now, to help us test, I have deleted the footer.txt file on the main ITTY server. Let me know if curl now works. 

 

We can also experiment by sending an article with only CRLFs through to AUTOSTART to see if curl dies. 

 

Paul

Yes I tried that but all I could see was data arriving and then curl dying. There didn?t seem anything odd about the data, but it was all binary. I could try to delve deeper but I thought the best starting point was to ask if there is any known difference between ITTY and the other feeds. Paul seemed to think that possibly some headers might be different.

Hello Paul,

 

It is fair to say that I will end up using the autostart feed rather than ITTY, but my sense of tidiness tells me that I would like to understand why ITTY kills curl stone dead, and I may want to use ITTY from time to time.

 

I think it would be good to fix this if the solution is easy to find and fix because others might have similar issues in future and not understand what is going on.

 

Thanks

I was just wondering if you ever got to look at this issue with ITTY killing curl while the Europe channel doesn?t?

?That is strange that the Europe channel is ok and the ITTY channel is not. I?d like to resolve this. 

 

The ITTY channels each have a footer transmission after the main transmission. Maybe the footers are different. I will look into this later today.

I have been trying these suggestions using curl to receive ITTY and pipe it through lame and minimodem. It works well.

 

However, I didn?t like that curl exits after every message. So, I thought I would try to write my own code that keeps going, using libcurl, which is what curl is built from.

 

I discovered though that the ITTY feed does something strange and it causes curl (and libcurl) to just silently exit at the end of a message. It never reaches my cleanup code, it just dies. I thought it was a problem with my code, but I don?t think it is, there is something specifically wrong with http://internet-tty.net:8000/ITTY that cause curl to die. I have been trying to work it out but have not found the issue yet. Is anyone aware of anything peculiar about the ITTY feed? It doesn?t seem to happen for the EUROPE feed, I am not sure yet about AUTOSTART and it is able to repeatedly download other URLs (www.example.com <http://www.example.com>  for example).

 

Thanks

Here are some aliases, which combine 'curl', 'lame' and 'minimodem'.   I haven't run these unattended for a while, and I seem to remember there are dropout situations that will break them easily - so you could then wrap everything in a loop if necessary.  But they might make a good starting point for you.

 


alias autostart='curl -N -s http://internet-tty.net:8030/AUTOSTART | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q -R 11025 -f -'
alias europe='curl -N -s internet-tty.net:8040/EUROPE <http://internet-tty.net:8040/EUROPE>  | lame --decode --quiet --mp3input - - | minimodem 50 -M 1275 -S 1445 -5 -i -a -q -R 11025 -f -'
alias itty='curl -N -s http://internet-tty.net:8000/ITTY | lame --decode --quiet --mp3input - - | minimodem rtty -i -a -q --rx-one -R 11025 -f -'

I already have the means to connect my ASR33 from software running on a Raspberry PI or a PC via reverse Telnet. The bit I am missing is what software (if any) there might be that I could run on a Raspberry Pi, or Windows that runs in the background (no GUI) to decode the ITTY audio signal. I am a software developer though, so I guess if such a thing doesn't exist then perhaps I can modify the MMTTY code that is published on GitHub.

Thanks for the resources all, I've been keeping my eyes on FB marketplace
and ebay but the options definitely are slim. One item I managed to see a
few times was a HAL DXP 38. This looks promising but I'm unsure if it's the
right equipment for what I need, connecting a model 15 to a radio. Has
anyone used this before, or does anyone know if this would work?

Thank you for the help,
Aidan W9POG

I am not at all familiar with the DXP 38, so decided to see what Google 
would tell me.

eham.net has reviews and users seem to like it.

However, I also found the user manual.  As far as I can tell there is no 
interface for a model 15, that is, no loop supply.  It appears that it 
is designed for an interface to a computer via RS-232 connection.

I recommend down loading the manual and reviewing it to see if it will 
do what you want.


73,
Gary

Got the following inquiery from a US based film maker through our website.

"I'm working on an archival documentary.
I'm in the US.
I have some police reports from 1963 that I'd like to film printed on a
teletype.
Doesn't have to be fancy. I can even be done with a phone.
Can you help? "

Anyone out there who likes to do the job?

Sure! I could do this, and I suspect many others on the list could. We'd
just need the text to be printed. I could "film" with a phone, or perhaps
the film maker would like to do the recording which may make another

Dear all,

I have been working on adjusting a model 19 printer mechanism (it is
identical to the model 15), I have aligned the motor speed, and no matter
how I move the side speed adjustment for the signal, it won't print RYRYRY,
I have it set properly through MMTTY and I am at a loss for what could be
wrong.

Has anyone had this issue, and if so how was it fixed?

Potential issues - The motor was aligned with a tuning fork of the correct
VPS, but I may have done it wrong.

Lots of questions, and probably useless facts from me?

What's your source of RY?

What do you mean by setting it through MMTTY?

What does it print for an RY signal?

By speed adjustment, I suspect you mean the range adjustment ... the 
thing with a 0 to 120 scale.   (might be off on the exact numbers, but 
my recollection is that mid range is 60)

I'm assuming a 2100 rpm motor and can't think of anything you could 
reference it to for comparison.  (there were some 1800 rpm governed 
motors used on TDs, but I suspect they are quite rare)

For 60 wpm (45 baud), the main shaft spins at 420 rpm and the keyboard 
at 368, again can't think of an easy reference other than the keyboard 
is only slightly more than 6 x  60 Hz line frequency. (now that I think 
of it 420 is 7 x, but you don't have anything to get a timing pulse like 
you could with the keyboard.)

I like to check speed by checking the bit timing with a scope. For 60 wpm,
the start and data bits should be 22 ms. If you hit an R or Y on the
keyboard and watch the loop (perhaps the voltage on a loop current limit
resistor) with a scope set to single trace, you should be able to see the
22 ms bits.

The range finder is used to center the sampling of the bit in the bit
time. Once you know the printer speed is right, sending continuous data
(RY or quick brown fox or whatever) and adjusting the range finder to find
the min and max settings for good print, then setting the range finder to
the mean of these two values.

Good luck!

Harold

Assuming the speed is correct and the Range Finder is set near 60 (only 
change it while receiving data), you may have stuck bits or a sluggish 
Selector Magnet armature.

What happens when you type repeated Blanks (00000) or repeated Letters 
(11111)?? (when you type to yourself, it won't matter what the motor 
speed is)

If you type on the keyboard while turning the motor by hand, you can 
watch the selector mechanism and the following levers in slow motion to 
see what is being decoded.

Do you have a manual?

Good luck,

Duncan,

Dear All,

I have kept my keyboard out as it has not been working, but I reconnected
it and it caused the motor to turn extremely slowly, and as I was seeing if
it would free up the motor made a sparking noise and died. Have I killed
the motor or is there some way to fix it??

If the motor only made noise and died without smoke or signs of really 
serious overheating, it may have survived. Check to see the motor 
brushes are of at least minimum length and not sticking in the brush 
holders. Check the governor contacts, sliprings, and brushes. If the 
correct fuse was installed for the motor, it may have done it's duty and 
protected it. Check the resistors in the motor and governor circuit, the 
overload might have fried one of them. Free up the keyboard before 
re-installing it, the governed motor is designed around a reasonable and 
fairly steady load as part of the speed regulation and won't survive 
serious overloads.

Not that some bases have a screw-in ?cartridge? fuse  in the motor circuit ? the typical classic house fuse ? see if you have one in your machie and (power off, unplugged) remove it and see if it?s blown.

A few hardware stores still carry these, or perhaps Amazon, etc would have one.

Someone on Greenkeys can also help.

Keyboard: it seems as if your keyboard assembly is jammed ? take it back out, and lubricate it ? there are oil cups and felts. When the shaft and gear rotate freely, re-install it and try it again.

It might also help you to have the documentation for your machine ? these are readily available from several sources.

Good luck ? we?re standing by?

Dear All, I have kept my keyboard out as it has not been working, but I reconnected it and it caused the motor to turn extremely slowly, and as I was seeing if it would free up the motor made a sparking noise and died. Have I killed the motor

Dear All,

I have kept my keyboard out as it has not been working, but I reconnected it and it caused the motor to turn extremely slowly, and as I was seeing if it would free up the motor made a sparking noise and died. Have I killed the motor or is there some way to fix it??

Message-ID: <ba651351-7562-40e6-8def-ad648e52c608@gmail.com>

Gang,

Does anyone have any ideas about refurbishing the print hammer pad for 
the Mites? I was thinking about a small polyurethane spacer/buffer 
(.050" thick) between the print hammer and the hardened print face 
adhered with some adhesive that can take the shock. I don't want to 
start draining the swamp if this has been addressed already. Thank you 
for your input if you have any experience in this area. Or if anyone has 
found any replacements.
