My father, Lawrence W. Jones, W8LUJ, died Friday morning at age 97.  He was a Signal Corps veteran, having served in the 35th (Santa Fe) Division in France, Belgium and Germany between 1944 and 1946.  After the war, he had a long and productive career in physics.  He taught me the fine art of tinkering with things mechanical and electronic, not to mention plumbing and carpentry.

Message-ID: <CAE1er5789hEkwP2y0a6-9dNvbZVUpsbYcaqi1O_2g_WUfmLAMQ@mail.gmail.com>

Hi all, happy 4th for those in the US!

First, attached you will find my first attempts at 3d printed key
replacements. These are on my GPE perforator. Not perfrct, but better than
nothing!

Second, https://youtu.be/5lkIvRWcB4A

This new model 14 printer I received appears to be further bent, or I
missed an alignment when mating the printer to the main shaft.

I am about ready to try and go back to the old frozen up printer, which at
least fully cycled properly. I am reading the manuals, but printer
replacement instructions I have not found.

If anyone has any ideas before I begin deep cleaning the old printer, I am
all ears! Thanks!

-Eric

Little update, I think I have the printer adjusted. Now I am struggling
with the cam stack pushing a release out of the way at the right time to
prevent the main shaft seizing.

A 14 chatters again!

https://youtu.be/UVSCk7ly5W0

The top / first code bar is not properly moving, and the bell I think is
the paper warning arm.

I have a spare encoder that came with the spare printer, so I am going to
do a transplant. It is only a partial encoder, but it has the piece that is
broken on mine.

I have Mike Douglas's RS232 adapter ready to go, so once I address the 1st
code bar I can send it some characters :)

Thank you all for the help!

Subject: [GreenKeys] 400 Hz MITE Power Supply
Message-ID: <CADo5+=JS-rspnHpEd4HgSYKQyJo8+XPY7T33-9xgUTQvRY6uBQ@mail.gmail.com>

I just got my 400 Hz MITE power supply kludged together for testing. It
works well! It uses a EGS002 SPWM Sinusoid Inverter Driver Board (slightly
modified) driving a MOSFET H-Bridge driving an old UPS transformer -
powered by a 12VDC 30 amp switching supply. It draws about 2 amps (DC) at
idle and about 8 amps when the MITE is powered on. Looks like the MITE
draws about 6 amps (x 12 Volts) or about 70 watts which is what the spec
says it should draw from the AC supply. The heat sinks stay cool. Now I
have to get rid of the RFI it generates - probably going to line the Apache
box with copper tape. Apparently, the distortion you see on the sine wave
is due to the voltage regulation of the EGS002 which varies the PWM pulse
width to regulate the voltage. The meter is reading the output voltage
feedback, which is compared against a 3 volt reference for regulation. Now
I don't have to swap out my one 60 Hz motor between printers for
troubleshooting. (The spare (400 Hz) printer needs some work, but will
print out the QBF message.)

Subject: [GreenKeys] RTTYART Capture Program
Message-ID: <CAAm=MFbycrYcFGnnsA7xkiPL=RtA_0v6KC+L3k70JJLONGDs4w@mail.gmail.com>

Hello group, I have been trying to make the RTTYART capture program to work
with my TTY setup. I have sampled off my demodulator output a TTL
signal which is fed onto the UART circuit that feeds the model 28
normally and works.. This TTL signal I fed into a MAX232 chip to
convert back to a RS232
signal and is connected to my serial port on the computer.. I installed the
program and set it up as best as I can figure after reading the documents
but
all I get is garbage on the display.. Groups of letters sometimes and so
on.. I am monitoring the ITTY signal as the source and my question is this:
Should I be seeing what the ITTY signal is being printed on my 28
machine??  The point where I am sampling the TTY signal is the normal 60
WPM signal
before it goes to the UART and is converted up to 100 WPM for my 28 that is
geared for 100 WPM...
Any suggestions will be appreciated.. Skip

Hello Eugene.. Well I know what your saying about ascii conversion etc..
I read the documents that are with the program and he describes it as
simply getting the TTY loop converted to RS232 for the computer is all..
The program has many selections in the setup to select Baudot and different
setting for it..
>From what I can read thats all there is..
At one point he says just connect after setting it up and type on the TTY
and it will show up in the monitor screen of the computer.. The capture
side shows the data being recieved and then stored, it looks like it's
working there..
But nothing but garbage all over the monitor screen..  So am curious what I
am missing.. Skip

I have had some success with this program.. I realized later that the TTL
signal I was sampling was inverted so once I got that straightened out the
program was copying the
TTY signal, mostly.. The only issue I have is that the cursor isnt always a
straight line but more a thick black block like you see in a text program
with the INSERT key on your
keyboard selected.. This black block overwrites the TTY character at the
time and does make a mess of things.. Sometimes its ok and its all good. I
suspect its a computer issue and I was able to capture and save a simple
pix I had from a perf tape.. I was able to load it in the editor section of
the program and it looked good.. I sent it out on the autostart feed and it
went through just fine..
So it seems to work mostly.. Just a report.. Skip

Several have figured out the project. The RY's are generated by sending 
a square wave using a 555. The 555 then drives an HSR series optical 
switch which keys the local loop. Dovetron does a similar operation with 
their RY generator. There are plenty of Chink 555 boards on ePay that 
are all ready built and cost is around 2 bucks.

That IS pretty clever! I assume the printer has auto CRLF since the
generator would only generate RY. Also, all bits would be the same length,
including the stop bit which, for 60 wpm is usually 31 ms long compared to
22 ms for the other bits. But, if we are sampling in the middle of the
bit, it seems like any stop bit longer than 11 ms would work. Thinking
about the square wave, I get

0 - start
1 - D0
0 - D1
1 - D2
0 - D3
1 - D4
0 - stop

So, it seems like we'd get framing errors on a square wave since the stop
bit is a 0.

Harold,
I cant see how a square wave would work.
If you listen to an off-air RY signal it has rhythmical brrr, brrr, brrr 
but a square wave wouldn't have the rhythmical breaks that make the stop 
bits.

There was an article for an RY generator by W7ZTC in the March 71 issue 
of Ham Radio.
It used some really old RTL chips MC-890-P and MC-824-P.
Maybe someone could redesign the circuit using standard LS TTL or CD4000 
series chips.

Seems that the Arduino could be coded to do that and have the 31 ms stop bit.  Most any speed could be set and the cr/lf added after a set number of characters.

Dovetron does a similar operation with their RY generator. There are plenty of Chink 555 boards on ePay that are all ready built and cost is around 2 bucks.

Could also do it with a PIC10F200
(https://ww1.microchip.com/downloads/aemDocuments/documents/OTH/ProductDocuments/DataSheets/40001239F.pdf
) for 60 or 70 cents. Add a power supply and an SSR to key the loop.

> So, it seems like we'd get framing errors on a square wave

Mechanical asynch receivers like TTYs don't detect framing errors, nor do they much care about them.

Here's what I would have expected.
1 --- idle line
0 - start
1 - D0
0 - D1
1 - D2
0 - D3
1 - D4
0 - stop (framing error, but note*
1 --- idle line, note **
0 - start
1 - D0
0 - D1
1 - D2
0 - D3
1 - D4
0 - stop
1 --- idle line, note **
0 - start

Note*: yes, a framing error, but the TTY doesn't care, it's simply insensitive to the state of the line for about 31 ms
Note**: for 9 ms, the line is ignored as part of the stop bit, the remaining 13 ms of this 1 bit are seen as an idle line.

The net result?  I wouldn't have expected RYRYRY, I'd have expected RRRRRR from just a square wave.

Unless what is happening is the following:
1 --- idle line
0 - start
1 - D0
0 - D1
1 - D2
0 - D3
1 - D4
0 - stop also sensed as a start bit for the next character ***
1 - note ****
0 - D0
1 - D1
0 - D2
1 - D3
0 - D4
1 - stop (not a framing error)
0 - start

Note***: framing error, clutch remains engaged, shaft continues to spin.
Note****: 0-1 transition was 9 ms before expected end of stop bit, too little time for it to matter.

This would give RYRYRY, but it would probably be rather sensitive to the rangefinder setting.  I'd expect the RYRYRY to sound a bit syncopated, that is, more like RY RY RY RY (not printing spaces, but a little off in the timing).

Good analysis! I agree that the "framing error" results in the shaft
continuing to rotate and go onto the next character. With a valid
character, I'd EXPECT (but do not know) that the shaft would stop rotating
11 ms into the stop bit (center of a 22 ms bit time, even though the stop
is usually 31 ms long). If there is an invalid stop bit (space), it would
"roll into" the next character with the start bit starting 11 ms after the
end of D4. It would then sample D0 33 ms later (22 ms for start bit and 11
ms to center in D0).

The software UART (
https://github.com/HaroldHallikainen/DSP_TU/blob/master/src/BaudotUart.c )
in my DSP TU (https://w6iwi.org/rtty/DspTU/ ). Detects the mark to space
transition for the beginning of the start bit and checks it again 11 ms
later to make sure it was a good start. If so, it then samples the input
every 22 ms to pick up the data bits. After the last data bit, it samples
another 22 ms later for the middle of the stop bit. If the stop bit is not
mark, it increments an error counter. I'm planning on reporting a ROUGH
error rate by comparing bad stop bits to good start bits.

By the way, I've started assembly of the DSP TU PCB (
https://w6iwi.org/rtty/DspTU2/ ). After soldering a few 0603 resistors
with a soldering iron, I ordered a hot air solder station and solder
paste. That should be here Monday.

I was curious about Doug's remark that the RY sequence created by the 
555 Square Wave generator might sound "syncopated".? His comment below. 
So? I made a short comparison video of? the 555 generator RYs and 
another RY source.

I want to run my 400 Hz MITE at 45 baud but only have a 50 baud speed gear.
A side benefit of my 400 Hz power supply is that the frequency is
adjustable. So, I adjusted the frequency to 360 Hz and voila! Now I can
print at 45 baud!

That's great! My brother has a machine shop with a lot of variable
frequency drives that are single phase in and three phase out. I've always
wondered if they would drive a single phase load (a Teletype). They are
amazingly cheap.

Sadness. I've purchased some cool stuff during several walkins.... It 
was great to walk around for inspiration too.

Indeed, sadness.  I've never been in the store being on the other coast 
but I have sure ordered from their catalog many, many times over the years.

I live about 1.5 miles from All Electronics and have been in there quite a few times. Several of months ago I noticed that all of the "Not for Sale" old test equipment was no longer there. Recent reports from around here first said that they were looking for a buyer with no luck but were possibly negotiating with employees to buy it but not successfully so far. A couple of days ago I heard that there might be some arrangement finally made with employees. We will see.
While in high school (1960) I used to work Sundays at Thrifty Electronics also in Van Nuys on Burbank Blvd. selling tubes, lots of surplus capacitors, and resistors as well as other small parts. Al Ex's (the big boss) cigars were gross and I had to wash off that smell when I finished the day.

I remember getting printed catalogs from All Electronics (I assume it was
the same company). It does seem like a difficult business to be in.
Determining what to price stuff at and how much to pay for the stuff is a
challenge. And, if you are going to sort stuff, write descriptions, take
photographs for a printed catalog or a web page... even more work! But I
do like "saving stuff from the dumpster."

There was an interesting store in Indiana we found while visiting my
sister-in-law. The store bought truckloads of surplus (appears to be
mostly retail returns). On Wednesday, everything in the store was $5.
Then, each day, the price was marked down a dollar. I imagine there was
some stuff they could not even give away at the end, and I don't know what
they did with that. But, this "reverse" or Dutch auction has always been
interesting to me. I've sold several things on Craigs list that way.

Here in Tucson, we are lucky enough to still have an electronic surplus
store AND an electronics parts house (

Some more OT nostalgia; How about "Sandy's" I think it was in the San 
Fernando Valley, Canoga Park on Saticoy, does anyone remember Saydy's? I 
was just a wee youngin', before the advent of Radio Shack. Good times 
with my Dad on Saturday outings.

There was one in Canoga Park on Saticoy as you remember and one very near to me on the southeast corner of Coldwater and Vanowen in North Hollywood (now an Armenian bakery).?
There is still Apex Electronics on San Fernando Road and near Lankershim in Sun Valley that has all kinds of things - parts and old electronic racks which are rented out to television and movie companies as props with only the lights flashing. That is a giant mess inside and a few employees or owners seem to know where everything is. It's amazing what they have in drawers and boxes in maybe 30-40 thousand square feet of space. A couple of months ago I went there to hopefully get 2 #4 ga insulated or uninsulated butt end connectors. It took someone all of maybe 15 seconds to come up with them at 50 cents each. Wire, tubes, mechanical things . . . it's always a surprise that they have it and a lot more.

It appears no-one is interested in coming to Western Kansas for the Model 28ASR, 
and boxes/rolls of paper and tape. Have had NO responses whatsoever. Next step 
will be to have salvage yard pick it up, Will get a few bux for it, they said can strip it of 
wiring and motor and scrap the steel. Then take the paper to the land fill. I'll hold 
off for a while before I take those measures. I really hate to do that. I have a lot 
of other stuff to dispose of also, mil gear, ARC-5. etc, most going to auction or scrap 
yard.

I would be interested, but I have no way to get up there.
If anybody knows of a truck heading towards junction, tx that is.
probably better if somebody else gets it though as I have no money at the
moment as I'm now unemployed again.
but I sure do hate to see it scrapped.

I'm sure you can sell it on eBay. If you make the price low, and the
shipping reflective of having someone package it for you at a box store
(i.e. high), you can probably get it to someone who wants it, at least.

Regarding pictures, I have some somewhere in computer. Give me next week I'll dig them out. We are 
getting ready for Co Fair and in middle of harvest, time is limited. 
As I mentioned before, I'd like to get a little something for the stuff. I'll try to get pictures and inventory of 
items put together. 
Also, I am NO help whatsoever in loading with bad back, you will need a dolly/cart to get in loaded I'd 
imagine.

I would be interested, but I have no way to get up there. 
If anybody knows of a truck heading towards junction, tx that is. 
probably better if somebody else gets it though as I have no money at the moment as I'm now unemployed again.

It appears no-one is interested in coming to Western Kansas for the Model 28ASR,

will be to have salvage yard pick it up, Will get a few bux for it, they said can strip it of

Hi RODNEY,
I am interested in your 28 ASR
can you supply me with some details-
Can you send photos ?
I am looking for a 28ASR with a typing reperforator, but will take one with a typing perforator if that is what it has.
In the latter case do you have a standalone typing reperforator with 60 wpm gears ?
I hear some people have either a mechanical switch or an electronic switch to change speeds. That would be great as well.
I would like 100 wpm gears also.

Thanks, Fred
VE3WN

Hello Eugene.. Well I know what your saying about ascii conversion etc..
I read the documents that are with the program and he describes it as
simply getting the TTY loop converted to RS232 for the computer is all..
The program has many selections in the setup to select Baudot and different
setting for it..
>From what I can read thats all there is..
At one point he says just connect after setting it up and type on the TTY
and it will show up in the monitor screen of the computer.. The capture
side shows the data being recieved and then stored, it looks like it's
working there..
But nothing but garbage all over the monitor screen..  So am curious what I
am missing.. Skip

I have had some success with this program.. I realized later that the TTL
signal I was sampling was inverted so once I got that straightened out the
program was copying the
TTY signal, mostly.. The only issue I have is that the cursor isnt always a
straight line but more a thick black block like you see in a text program
with the INSERT key on your
keyboard selected.. This black block overwrites the TTY character at the
time and does make a mess of things.. Sometimes its ok and its all good. I
suspect its a computer issue and I was able to capture and save a simple
pix I had from a perf tape.. I was able to load it in the editor section of
the program and it looked good.. I sent it out on the autostart feed and it
went through just fine..
So it seems to work mostly.. Just a report.. Skip

I have a nice Mite unit but it is without a keyboard. Is there keyboards available? If so, could you please provide source information.

Thanks in advance for any help.

Several have figured out the project. The RY's are generated by sending
a square wave using a 555. The 555 then drives an HSR series optical
switch which keys the local loop. Dovetron does a similar operation with
their RY generator. There are plenty of Chink 555 boards on ePay that
are all ready built and cost is around 2 bucks.

That IS pretty clever! I assume the printer has auto CRLF since the
generator would only generate RY. Also, all bits would be the same length,
including the stop bit which, for 60 wpm is usually 31 ms long compared to
22 ms for the other bits. But, if we are sampling in the middle of the
bit, it seems like any stop bit longer than 11 ms would work. Thinking
about the square wave, I get

0 - start
1 - D0
0 - D1
1 - D2
0 - D3
1 - D4
0 - stop

So, it seems like we'd get framing errors on a square wave since the stop
bit is a 0.

Harold,
I cant see how a square wave would work.
If you listen to an off-air RY signal it has rhythmical brrr, brrr, brrr
but a square wave wouldn't have the rhythmical breaks that make the stop
bits.

There was an article for an RY generator by W7ZTC in the March 71 issue
of Ham Radio.
It used some really old RTL chips MC-890-P and MC-824-P.
Maybe someone could redesign the circuit using standard LS TTL or CD4000
series chips.

Seems that the Arduino could be coded to do that and have the 31 ms stop bit.  Most any speed could be set and the cr/lf added after a set number of characters.

Could also do it with a PIC10F200
(https://ww1.microchip.com/downloads/aemDocuments/documents/OTH/ProductDocuments/DataSheets/40001239F.pdf
) for 60 or 70 cents. Add a power supply and an SSR to key the loop.

> So, it seems like we'd get framing errors on a square wave

Mechanical asynch receivers like TTYs don't detect framing errors, nor do they much care about them.

Here's what I would have expected.
1 --- idle line
0 - start
1 - D0
0 - D1
1 - D2
0 - D3
1 - D4
0 - stop (framing error, but note*
1 --- idle line, note **
0 - start
1 - D0
0 - D1
1 - D2
0 - D3
1 - D4
0 - stop
1 --- idle line, note **
0 - start

Note*: yes, a framing error, but the TTY doesn't care, it's simply insensitive to the state of the line for about 31 ms
Note**: for 9 ms, the line is ignored as part of the stop bit, the remaining 13 ms of this 1 bit are seen as an idle line.

The net result?  I wouldn't have expected RYRYRY, I'd have expected RRRRRR from just a square wave.

Unless what is happening is the following:
1 --- idle line
0 - start
1 - D0
0 - D1
1 - D2
0 - D3
1 - D4
0 - stop also sensed as a start bit for the next character ***
1 - note ****
0 - D0
1 - D1
0 - D2
1 - D3
0 - D4
1 - stop (not a framing error)
0 - start

Note***: framing error, clutch remains engaged, shaft continues to spin.
Note****: 0-1 transition was 9 ms before expected end of stop bit, too little time for it to matter.

This would give RYRYRY, but it would probably be rather sensitive to the rangefinder setting.  I'd expect the RYRYRY to sound a bit syncopated, that is, more like RY RY RY RY (not printing spaces, but a little off in the timing).

Good analysis! I agree that the "framing error" results in the shaft
continuing to rotate and go onto the next character. With a valid
character, I'd EXPECT (but do not know) that the shaft would stop rotating
11 ms into the stop bit (center of a 22 ms bit time, even though the stop
is usually 31 ms long). If there is an invalid stop bit (space), it would
"roll into" the next character with the start bit starting 11 ms after the
end of D4. It would then sample D0 33 ms later (22 ms for start bit and 11
ms to center in D0).

The software UART (
https://github.com/HaroldHallikainen/DSP_TU/blob/master/src/BaudotUart.c )
in my DSP TU (https://w6iwi.org/rtty/DspTU/ ). Detects the mark to space
transition for the beginning of the start bit and checks it again 11 ms
later to make sure it was a good start. If so, it then samples the input
every 22 ms to pick up the data bits. After the last data bit, it samples
another 22 ms later for the middle of the stop bit. If the stop bit is not
mark, it increments an error counter. I'm planning on reporting a ROUGH
error rate by comparing bad stop bits to good start bits.

By the way, I've started assembly of the DSP TU PCB (
https://w6iwi.org/rtty/DspTU2/ ). After soldering a few 0603 resistors
with a soldering iron, I ordered a hot air solder station and solder
paste. That should be here Monday.

I was curious about Doug's remark that the RY sequence created by the
555 Square Wave generator might sound "syncopated".? His comment below.
So? I made a short comparison video of? the 555 generator RYs and
another RY source.

"This would give RYRYRY, but it would probably be rather sensitive to the rangefinder setting.  I'd expect the RYRYRY to sound a bit syncopated, that is, more like RY RY RY RY (not printing spaces, but a little off in the timing)."

I want to run my 400 Hz MITE at 45 baud but only have a 50 baud speed gear.
A side benefit of my 400 Hz power supply is that the frequency is
adjustable. So, I adjusted the frequency to 360 Hz and voila! Now I can
print at 45 baud!

That's great! My brother has a machine shop with a lot of variable
frequency drives that are single phase in and three phase out. I've always
wondered if they would drive a single phase load (a Teletype). They are
amazingly cheap.

Sadness. I've purchased some cool stuff during several walkins.... It

Indeed, sadness.  I've never been in the store being on the other coast

I live about 1.5 miles from All Electronics and have been in there quite a few times. Several of months ago I noticed that all of the "Not for Sale" old test equipment was no longer there.

I remember getting printed catalogs from All Electronics (I assume it was
the same company). It does seem like a difficult business to be in.
Determining what to price stuff at and how much to pay for the stuff is a
challenge. And, if you are going to sort stuff, write descriptions, take
photographs for a printed catalog or a web page... even more work! But I
do like "saving stuff from the dumpster."

There was an interesting store in Indiana we found while visiting my
sister-in-law. The store bought truckloads of surplus (appears to be
mostly retail returns). On Wednesday, everything in the store was $5.
Then, each day, the price was marked down a dollar. I imagine there was
some stuff they could not even give away at the end, and I don't know what
they did with that. But, this "reverse" or Dutch auction has always been
interesting to me. I've sold several things on Craigs list that way.

Here in Tucson, we are lucky enough to still have an electronic surplus
store AND an electronics parts house (
https://elliottelectronicsurplus.com/ ).

Some more OT nostalgia; How about "Sandy's" I think it was in the San
Fernando Valley, Canoga Park on Saticoy, does anyone remember Saydy's? I
was just a wee youngin', before the advent of Radio Shack. Good times
with my Dad on Saturday outings.

There was one in Canoga Park on Saticoy as you remember and one very near to me on the southeast corner of Coldwater and Vanowen in North Hollywood (now an Armenian bakery).?
There is still Apex Electronics on San Fernando Road and near Lankershim in Sun Valley that has all kinds of things - parts and old electronic racks which are rented out to television and movie companies as props with only the lights flashing. That is a giant mess inside and a few employees or owners seem to know where everything is. It's amazing what they have in drawers and boxes in maybe 30-40 thousand square feet of space. A couple of months ago I went there to hopefully get 2 #4 ga insulated or uninsulated butt end connectors. It took someone all of maybe 15 seconds to come up with them at 50 cents each. Wire, tubes, mechanical things . . . it's always a surprise that they have it and a lot more.

It appears no-one is interested in coming to Western Kansas for the Model 28ASR,
and boxes/rolls of paper and tape. Have had NO responses whatsoever. Next step
will be to have salvage yard pick it up, Will get a few bux for it, they said can strip it of
wiring and motor and scrap the steel. Then take the paper to the land fill. I'll hold
off for a while before I take those measures. I really hate to do that. I have a lot
of other stuff to dispose of also, mil gear, ARC-5. etc, most going to auction or scrap
yard.

sorry, did not put in correct subject line on last post.

Hi RODNEY,
I am interested in your 28 ASR
can you supply me with some details-
Can you send photos ?
I am looking for a 28ASR with a typing reperforator, but will take one with a typing perforator if that is what it has.
In the latter case do you have a standalone typing reperforator with 60 wpm gears ?
I hear some people have either a mechanical switch or an electronic switch to change speeds. That would be great as well.
I would like 100 wpm gears also.

Thanks, Fred
VE3WN

> Do you know anyone that may be interested in my Flexowriter FIO? (picture attached) Any leads are appreciated.

I just got the above e-mail from Joe Clanin.  I know nothing about the Flexowriter FIO other than what I found on these threads:
-- https://www.reddit.com/r/Teletype/comments/j76a1y/my_friden_flexowriter_fio/
-- https://forum.vcfed.org/index.php?threads/friden-flexowriter-fio.75486/

Joe sent me the identical photo to the one on the reddit thread, so I assume it's the same machine.  From the vcfed thread, I found this photo of the punched tape code the machine uses:
-- https://i.imgur.com/BYft7YY.png

If this machine interests you, please contact Joe at the e-mail address listed above.

The punched tape code is interesting, so I took the time to try reverse engineering it:
 87654s321
channel s is the sprocket
channels 1234 are a binary code, low bits
channel 5 is parity (so there are always an odd number of holes)
channel 67 are a binary code, high bits
channel 8 seems used only for carriage return

If I ignore the control characters, it's a monocase code closely related to IBM's 027 punched card code, where the low bits 4321 indicate a 1 out of 9 code for the numeric punches (code 0000 means punch nothing), and the high binary bits are:
   76 = 11 -- zone punch card row 12
   76 = 10 -- zone punch card row 11
   76 = 01 -- zone punch card row 10 (aka row 0)
   76 = 00 -- no zone punch
Those rules handle letters and figures correctly for tape-to-punched card codes.  Also space (punch nothing).

Anyone gots any books/manuals to these? Since Nick has every Teletype
document under the sun I figured I'd try here and see if something pops up.
This is a CRT terminal that sort of has an identity crisis - Its Teletype
labeled on the back as a Teletype 56D, but has At&t 513 badging on the
front and supposedly from searches comes up as an At&t 513, 513BCT, 4425,
or others. This is probably one of Teletypes last products per se.

These were used a lot on PBXes like At&t Definitys from what I understand.
They're not too common per se but I've seen a few, and now own one myself.
Seems I managed to bring it back from the dead (was told it was a "barn
find") but no books/manuals on it.

If anyone did have the book I'd be glad to scan it and/or upload to Nick
and the Internet Archive.

Ohhhhh you picked this up from the system source swap meet from Paul didn?t
you?
We were thinking of taking it for the Museum.

I was asking about it and someone beat me to the draw on making an offer
haha, no harm done saved me the money.

My friend from the museum said it may have been one of the terminals
marketed for the 3B1?s multi user mode. The manual may be in the 3B1/PC7300
documentation set. I know that?s many books long. I hope that helps with
the manual search.

Hope you have fun with it! If you ever want to part with it feel free to
let me know!

I didn't even notice the 15 in the pic! That said I DID notice the URA-17s
there. Little info; the ham that was previously leading the charge with
getting them on the air passed back in Sept 2022, so another gentleman is
working on taking over the call (best sub call ever - N3SUB) and keeping
the radios warm, but I haven't heard back from him since then which was a
couple mos ago.

I noticed the URA-17s and immediately thought they would be a perfect ship
to ship test once we get some clattering back into the NJ. They are
literally across the river from the NJ, we can see each other, almost throw
a rock and hit each other. Also the Becuna is right next to the Olympia
(which has radios but not sure if they have any TTY gear, as that ship
almost predates TTYs!)

The character counter can be on the right side.  But, the punch cover doesn't quite look kosher to me.  Instead of being flat on top, it almost looks like there could be window there.  Isn't there supposed to be a  "button" on top for backing up the tape for a rub out?

Too bad they didn't include more of the TTY in the picture.

Nick,

The early M19s had the character counter on the right side of the keyboard.

paper but it did an OK job. I used 1.75" cash register paper and made 
the roll you see in the photo.? They're small rolls, but will do the job 
I'm sure.? All in all, pretty satisfied.? I'd prefer that it had some 
set screws to lock the side plates in place but they didn't budge while 
using it so I guess they're not really necessary.? I'm going to try and 
find some 2-ply register paper and see if it does a better/easier job 
cutting that.

I found that on amazon. Could be useful to make Kleinschmidt tape or ? inch ticker tape. I don?t own one just passing along where to buy one.

I?m very new to teletypes, and I want to get my model 19 running. I?ve done
the hard part of cleaning, but now I need a 120VDC 60MA power supply. Is
there any that you would recommend?

I thought that the Olympia almost predates radio. Any radio equipment
installed anboard it would not be an original installation!

I would recommend picking up a TU. You will probably want to print ITTY at
the very least. Most TU's have an internal 60 ma loop supply except for the
HAL ST-8000 and 8000A. Keep checking eBay. Some can be had very reasonably.

Just curious. Current loop
Is fixed current (or open) so the need for voltage is dependent on the loop resistance as per Ohms law? so given that most modern installs are ?short loop? (ie often in the same room), why the need for something that can supply that much voltage?????

A nice little supply is the Teletype 152950 used in M28 machines. Check
with Paul Cembura (Mr. RTTY) to see if he has any.

And you?ll need a 2000 ohm 10 watt resistor too, of course.

Have fun
Nick

A good question. High voltage with a current limiting resistor is used to
overcome the inductance of the selector magnets and make the selector
armature move quickly enough. Inductors resist a rapid change of current
and the time constant is proportional to L/R, so a larger R means quicker
movement.

There are transistorized selector magnet drivers using a lower magnet
voltage, but 120vdc with 2000 ohms in series is the most common setup.

Thanks. I was not thinking about the selector magnet inductance. I was simply going on what worked very well on my 33?s with lest than 25V @20mA

Look up TIME CONSTANTS in inductive series circuits.

L / R      the L is fixed in the selector magnet
              so the larger the R is, the faster the current
              changes from zero to 60 mA.

Are you up to building simple circuits ?

 

For a simple one you can get a wall wart of around 12 to 20 volts at an amp and a half or so, a up converter circuit board off ebay  for around $ 5 a 10 to 20 watt resistor of around 1000 to 2000 ohms.  Drive the up converter with the wall wart, put the resistor in series  with the printer magnets and adjust the voltage to get the 60 ma for the loop.  The voltage is not critical at all from around 70 to 200 volts.  It is the current that maters it needs to be close to 60 ma?  Do not go over that or possible damage to the magnet windings may happen.

 

To operate the tape punch it needs around 100 volts at 1 amp as I recall.  Just to use the printer and keyboard all you need is the 60 ma loop.

 

As you can see from the above the voltage is not critical, it is the current..  The magnets will pull in at a much lower voltage, however due to the inductance of the magnets  , the printer will not work very well with voltages less than 50 volts and the higher the voltage the better the printer will work.

I am on my phone right now, but when I get back to my desk I will post what I built last year. It can easily be changed from 20mA to 60mA and is a fixed current supply (along with detector so it can be used for either)

There are two reason for the older machines.

 

The main reason is what is known as the DV/DT.  In simple terms the inductance of the magnets slows down the current going through the coils.  This means the magnetic field takes a while to build up.   The higher the voltage, the faster the field builds up.  This happens several times for each letter. .  Some of the newer printers have a magnet of fewer inductance and a local loop to operate that.  They can work with a external loop of much lower voltage.

 

The other reason is on machines like the 15 printer it keeps the oil burnt off the contacts of the keyboard.

Just curious. Current loop

Is fixed current (or open) so the need for voltage is dependent on the loop resistance as per Ohms law? so given that most modern installs are ?short loop? (ie often in the same room), why the need for something that can supply that much voltage?????

I would recommend picking up a TU. You will probably want to print ITTY at the very least. Most TU's have an internal 60 ma loop supply except for the HAL ST-8000 and 8000A. Keep checking eBay. Some can be had very reasonably.

Nope not yet.  He is hard to pin down because if his job.  As soon as he has a couple of days in Astoria we are going out to look to hopefully move it to a place where we can distribute it out.  

When that time comes I will send pictures to all.

Subject: [GreenKeys] Wanted: MD-239 FSK Modulator
Message-ID: <3935f002-2ec4-d2db-a0ad-26f8db1d0976@earthlink.net>

Anyone have a MD-239 FSK Modulator that they could part with?

This is the modulator used with the T-368 transmitter in the AN/GRC-26D 
Radioteletype Set.

The AWA Museum just added a 1000 sq ft "Ham Shack" addition with about 8 
stations of varying vintages.? One station is a T-368 and a R-390, which 
seemed a natural for a RTTY station.? All I need is the MD-239.

Thanks,

I've just learned that I will need a TU to transmit over HAM radio as well
as connect to my computer and use it as a keyboard/printer/ITTY, what would
be a good unit to get?

Are you using a mechanical TTY, or just the computer?  If it's just the
computer you may want to consider the program FLDIGI ( http://www.w1hkj.com/
).   I use FLDIGI to copy ITTY on a glass display.  No TU needed.  It's all
in the PC.

Here's a list:  HAL ST-6, ST-5000, ST-6000. Flesher TU-170. IRL FSK-1000.
Dovetron MPC-1000.

The simplest and most basic (and the earliest) is the ST-6. The Dovetron
MPC-1000 offers the most flexibility (it is what I use most of the time
with my M19 and M28ASR). All these TU's have built-in loop supplies. Any
one of them will get you going. There is a lot of information online
(manuals, etc.) about these TU's. Google is your friend. There haven't been
many TU's for sale on eBay lately, but they show up every once in awhile.
Much of the time they are in working condition, but might require some
repairs.  You can also put up a query on Greenkeys. Maybe someone has one
for sale.

If only using a computer you do not need a TU.  There are many sound card programs for rtty. MMTTY is a very food free one.  There are other programs that decode rtty and other digital  modes.  You do need an audio interface that is just a simple circuit to isolate the computer and radio. It can be the same kind that is used for PSK31 and FT8.  You can even just put the microphone of the computer next to the radio  to receive rtty and other digital modes.  You could do the reverse to transmit but not advised as any other sound in the room would get transmitted and not be legal except maybe an FM or AM signal in the VHF bands.

 

If a mechanical teletype machine you will need a TU (modulator/demodulator) from the radio.

    Yay, it worked! Here is my test and I got only one copy. I will now 
go back to lurking.
     However, a note: I had MTTY on my now dead Acer laptop. It really 
has no practical way to connect an external line to it (or else I was 
too dumb to figure it out). I could use MTTY to listen to RTTY signals 
on the air via the receiver speaker and computer microphone but its very 
inconvenient.  I now have a Lenovo Think Pad. I think its possible to 
connect a line level audio input. Not sure yet, still learning this 
machine.
