Hi Mike,

Have a look at these attached photos.  Not the best, sorry.

Someone in the Discord noticed it on Usagi Electric's recent video.  He
pointed it out to me, which led to me looking at my machines which both
also have the imprint.

Thought it was interesting enough to put to the other folks in the
community.

Thanks,

John

Hello Duncam,

what do you mean with "down"?

i-Telex cannot be down in general as it does not work through a single
server
or any single point of fail.

What problems do you have in pariticular? e.g. did you want to dial up to a
certain number
and got bk?

Gang,

I found a simple two IC terminal unit for anyone that might want to try 
mechanical rtty on a budget. I think I'll layout a board and give it a

I built a demodulator like that (based on the NE565) back then. I don't
think the 741 limiter gains you anything. It's pretty easy to just
saturate the NE565 input as a limiter. The datasheet (which includes a
very similar demodulator https://www.fabian.com.mt/viewer/44073/pdf.pdf )
says only 10 mV is required for the PLL to lock.

A nicer (obsolete) chip is the XR2211 (
https://assets.maxlinear.com/web/documents/xr2211av104.pdf ). I designed
several products around this chip. It includes the PLL of the NE555 along
with the data slicer (comparator typically wired as a schmitt trigger) and
a lock detector (mark hold). As shown at figure 11
https://assets.maxlinear.com/web/documents/xr2211av104.pdf#page=14 , the
lock detect and FSK demodulator outputs are open collector, so they can
just be tied together to get mark hold.

 Long ago I tried a simple phase locked loop very similar to that. It did not perform well in the ham bands, probably due to poor signal to noise inputs.?

 I thought that sounded familiar.? Your link goes to a design called the NS-1 by?Nat Stinnette W4AYV.? The link takes us to a Feb 1975 version in Ham Radio.? It appears he later deleted the input 741 amplifier & wrote that the PLL alone was so sensitive that it wasn't needed.? So, it went to a 2 chip board (NE565 PLL & 741 comparitor).? I'd ordered one of his boards back then to build mine.
If you were to work up a PC board for this, I would be interested in that.? I have a use for a simple TU that will only be fed clean AFSK inputs.
FWIW, I also had made up a PC board layout for the Eric Volpe demodulator that used the XR2211. I extended some of the traces & lands to accommodate parts with slightly wider lead spacings.? Should have also changed the connector lands.? I had a few boards made & have tested one but only briefly.
Here's more links to Nat's NS-1.

While speaking of the simple TUs is there a source for the 88 millihenry
coils ?  The ST-5 is very simple and works very well but needs 2 of the
coils.

I built a demodulator like that (based on the NE565) back then. I don't
think the 741 limiter gains you anything. It's pretty easy to just
saturate the NE565 input as a limiter. The datasheet (which includes a
very similar demodulator https://www.fabian.com.mt/viewer/44073/pdf.pdf )
says only 10 mV is required for the PLL to lock.

A nicer (obsolete) chip is the XR2211 (
https://assets.maxlinear.com/web/documents/xr2211av104.pdf ). I designed
several products around this chip. It includes the PLL of the NE555 along
with the data slicer (comparator typically wired as a schmitt trigger) and
a lock detector (mark hold). As shown at figure 11
https://assets.maxlinear.com/web/documents/xr2211av104.pdf#page=14 , the
lock detect and FSK demodulator outputs are open collector, so they can
just be tied together to get mark hold.

 Yep, there're still some around but I don't think the telco uses them? anymore.? I have a couple of the cylindrical telco assemblies stashed away but might have a couple of the removed ones that I could let go of.? I'd want to run them past a digital inductance meter to be sure they weren't partially unwound at some time in the past.

 Hi Mike,
Have a look at these attached photos.? Not the best, sorry.
Someone in the Discord noticed it on Usagi Electric's recent video.? He pointed it out to me, which led to me looking at my machines which both also have the imprint.
Thought it was interesting enough to put to the other folks in the community.

I've seen stuff like that printed on the raw fiberglass used to make a

I don't know is this has been covered earlier, my greenkeys search does 
not seen to work properly, but I have been looking for budget roll paper 
for my 28asr. This is what I am using now.

Gang,

I am trying to read an article from the RTTY Journal Dec. 1978, AFSK 
Generator about p.16, (attached). The generator uses an EXAR 2206 chip. 
On the hand drawn schematic, I cannot read the pinouts, especially the 
lower part of the chip around C3. Can't read the numbers or if there are 
connections or pass throughs. On the schematic some obvious crossovers 
are dotted for connections, some obvious connections are not dotted.? 
Right around C3 is the issue. Is anyone familiar with this circuit or 
have a better copy?

73,

Try enlarging the schematic.  It seems easy to see if you enlarge the schematic to the point that you can only see a small part of the schematic.  The pins are laid out in order like 1,2,3,4,5,6,7.

Have a look at
https://pdf.datasheetcatalog.com/datasheet/exar/XR2206v103.pdf#page=9 .

The XR2206 is an interesting chip! It starts with a triangle wave
generator. The frequency is determined by a capacitor and resistor. The
timing resistor is switched between two external resistors by the logic
level on pin 9. There is a sine shaper that converts the triangle wave to
a sine wave. There is an analog multiplier (balanced modulator) where the
sine or triangle wave is multiplied by an external voltage. It is a
balanced modulator in that the output phase flips as the modulating signal
passes through its midpoint. There is also an open collector square wave
output.

In the 1970s and 1980s, I used the XR2206 in several products. I used it
as an AFSK generator using Bell 202 tones. I used it as a linear FM
modulator to generate subcarriers for broadcast studio to transmitter
links (110 kHz) and FM broadcast (67 or 92 kHz). I used it as a frequency
converter where the multiplier is used as a balanced mixer to convert a
subcarrier frequency (one of those listed above) to 455 kHz where it went
through an IF amplifier with ceramic filters, then an FM demodulator based
on a ceramic discriminator. The oscillator function in the XR2206 was the
local oscillator for this frequency conversion. These are all used in
https://bh.hallikainen.org/uploads/HfDrc190.pdf .

Thanks to Duncan and the AWA, the RKB-1 manual is now posted at
https://www.navy-radio.com/rtty/hal.htm

This keyboard and the Morse MKB-1 use a character coding scheme I have
never seen before. A wire from each key is threaded (or not) through a
series of toroids, one for each ?bit? in a character. Through is mark, skip
is space. Similarly for dot-dash in the Morse version. A pulse is fired
through the wire when a key is depressed and the secondary of the toroid
sets the corresponding bit in a shift register. Cool!

I've heard this technology referred to as a braided-wire memory.  In Wikipedia, it's called core rope memory.

Normally the ITTY service is fed to a piece of hardware called a terminal unit (think modem). The service is streaming as RTTY which is normally sent over amateur radio.

Hello,

Dave was asking this on my behalf, probably unaware that I am on this list too.

I have seen mention of ITTY Autostart etc and wondered about receiving all this on my ASR 33.

My thought was to see if I could set up a Raspberry Pi to receive the audio signal over the internet, translate that to ASCII and then send it to my ASR33. 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.

Any pointers would be welcome.

Thanks

Rob

It?s not hard to demodulate the audio in software with an input capture timer on a microcontroller, Arduino, etc.  I?m not familiar enough with the pi hardware to know if it can do the same thing or not. Here are two devices I?ve made that decode FSK audio using software:

  https://deramp.com/model15_interface.html
  https://altairclone.com/cassette.html

If you want to start with either of these pieces of hardware, the Altair cassette interface board would be the easiest to connect directly to gpio pins on a pi. You?d have to write software to monitor the gpio data pin and do a ?reverse bit-bang? to receive the 45.5 baud data stream into 5-bit baudot. That could then easily be converted to ASCII and sent to your ASR 33 (assuming you have an RS-232 adapter for your 33).

If your ASR 33 is still connected by current loop, then it might be easier to update firmware in the model 15 interface board to convert the FSK it receives to 110 baud ASCII and drive the 33 directly.

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 hve used an AEA PK-232 to do this. The 33 is connected to the PK-232's console port, which is configured for 110 ASCII. (The 232 has an 'autodetect' feature which will set itself up for the correct terminal device)
The the 232 is commanded into Baudot mode (By typing 'BA' on the 33) and incoming AFSK will appear on the console device. It's quite wierd to have the ASR33 clacking away at 45 baud - less than half it's "normal" speed - but it works well and I have used it at several demos I've run with Baudot and ASCII machinery running in parallel at the same time.  I've also decoded Morse this way.

I know that there were several other similar devices available which also used an RS-232 / ASCII console and decoded various signal on their audio inputs. The PK-232 is the one I'm familiar with and seems to work well.  And the are not hard to find - I've had several of them over the years. Documentation is also archived in various places.  Look for HAL, Heathkit, Kantronics, etc.

Finally one could use a USB - to Serial converter and run MTTY, FLDIGI, or similar, and send the output to the 'serial' port ad thus to the ASR33

I keep forgetting about these. They can also be used in pairs as a converter; send ASCII in, have it talk RTTY to another (or a TU) as an ascii to baudot adapter.

Anyone know what the pinout for this is? I gather from advertisements I
found it should be 60ma.

Rob,

Sorry, I disposed of a? PK232 a while ago but I do have a couple of 
spare RTTY decoders which I don?t use. Perhaps one of those will 
suffice, but I am in Spain for a couple of weeks so can?t check

I don?t seem to be able to find a PK232, but in any case, I think I am going to look into using minimodem and possibly adapting it for my needs. I rather like the idea of a software-based solution anyway.

 

Thanks for all the inputs. Lots to look into.

 

Regards

 

Rob

ITTY to real Teletype (Rob Jarratt)       seven

Might want to consider an arduino TEENSY 4.1 , it can go down to 45.45 or
110  baud pretty easily,
AND convert from one to the other. Also try using an HF radio, someone
could send you test code
ASCII to trigger what you what.

Take a look at this one...looks like a 15, but its a tape printer
(puncher?) like a 14.

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 | 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've heard this technology referred to as a braided-wire memory.  In Wikipedia, it's called core rope memory.

Has to be all or nothing.   If no takers, it has to go to scrapyard for salvage.    I don't really want that!  801-784-7524  leave message, if I am not there.

Subject: [GreenKeys] Flesher Filter Boards
Message-ID: <CADo5+=Kn1sCxfSgRELEjMGEtOA+vjj5Cg8D51Y8HpuRSE-GA=g@mail.gmail.com>

If anyone has wanted to add 425 Hz or 850 Hz shifts to their TU-300 or
Heathkit HD-3030, or wants a spare active filter board for their TU-470,
TU-300, TU-170A, or Heathkit HD-3030, I have the solution. I wanted a fully
populated HD-3030, so just for fun, made a KiCAD project to duplicate the
Flesher board. The result is a nearly exact replica of the Flesher board.
If anyone wants one or two, let me know. Or, you can order a batch from
PCBWay.

Hello Hugh,

 

When you refer to ?lame? do you mean compiling this: https://lame.sourceforge.io/download.php?

 

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 -'

Yes, although I just installed it with `apt` (on Raspbian linux) rather
than compiling from source.

Message-ID: <CA+H6KCnQHQZrjxQ+hhog3Q0bHgWv0ZUoLqKSYq=cqC-+XqPzmQ@mail.gmail.com>

Hello everyone - apologies as I cannot actually recall which emails this
relates to... but forgiveness is a key here!

Anyway, bottom line - Teletype 32 in awesome condition - but unfortunately
that's for the first 15 seconds, give or take.  At that point this fuze
blows.  I remember something (was that you, Wayne? ?) but that's the
extent of it.

As I recall it *used* to work just fine printing messages from the itelex
forum.

Any thoughts folks?

Subject: [GreenKeys] Lorenz LO15 Gears
Message-ID: <DM6PR11MB27953C88139F22F799F89894967A2@DM6PR11MB2795.namprd11.prod.outlook.com>

I'm wondering if anyone knows what speed these gears are on this Lorenz LO15.  I'm pretty sure this machine was used for Telex service in Canada, but it could be that a previous owner has already changed them to a 60 WPM set.  I don't yet have the machine with me so I can't read any numbers off the gears.  Does anyone know?

Thanks for your help.

Named Antique Wireless Association Fellow -

*Duncan Brown K2OEQ*
Duncan is an Assistant Museum Curator, has been an active member of AWA
since 2005, for most of that time has been a contributing member of the
Museum Staff, and brought us an unusual and much needed military training
background in Radio teletype communications. Those skills were much needed
by the AWA Museum and Duncan?s personal interest in the subject has made
him a recognized expert in the field.  Over the years, due to his
dedication and leadership, he has established at the AWA Museum a
recognized world class collection of RRTY equipment and historical
artifacts and shares his knowledge other like-minded historians everywhere.
We are lucky to have Duncan Brown in our service and his already
demonstrated accomplishments are worthy of this recognition.
Duncan has received the 2023 AWA Vice President?s Award.

A Model 15 housed in a Western Union letter box cabinet appeared in the museum yesterday. We already have three Model 15s to work on but thought we might be saving this one from the scrapper. I wonder if there's someone out there who's been lusting for a letter box machine? Located in Colorado Springs. Can send some pictures for anyone interested. AC synch motor driven. I think it's set up with a standard communications character set & it also has a "Here Is" mechanism installed.

Looks like it has the typical Anderson Jacobsen plug for a modem.

Might use this for parts, the carriage is seized solid due to dried lube. Case is cracked on the right.

Thanks. I hate partying with things also but I?m also at that phase in life when I need to start downsizing otherwise I?ll be leaving my widow with more work.
There was someone with a metal 3-D printer who is trying to create new print cylinders. But I don't know how that ever turned out.

Im in Philly burbs. I think I have an extra 32 printer mech (or a pile of one) but I dunno. I need a print head for my "good" 32 and the paper tape switch for a 33. Parting is normally against my religion so I will certainly
Check it out first. I also dont have any spare lids.

Lets see if this gets through the system, then. The center front folds upward for access to the machine. Presently the Model 15 is out of the cabinet (ease of moving it about).

I have the black letter box (mailbox?) currently, and the part that the
machine sits on "rolls out" from the front on its own table for servicing.
So you flip up the lid, then pull the machine towards you, but its not just
a shelf, the shelf plus a set of feet roll out. Assuming the one I have is
the standard mailbox case.
