Afternoon All...? (From a wet day in the UK.)

Some time ago (back in the day of Linux Mint 15!), I helped "flesh out" a new(ish) backend for the Kenwood TS870.? Receiving much welcome help and hints from Dave and Ed via this list.

Sometime later (years.) ? ISTR there was mention of (or proposal for) a documented guide for a "How to" showing the correct way to create a new radio backend for Flrig, doing that either based on an existing similar rig, or new "from scratch".

I also seem to recall, Dave 'HKJ sent me something around the same time, but can I find that, anywhere?? Of course not.? Even if I could, I suspect things have changed within Flrig since then...?? I can't see anything in the wiki area either.

So, is there an up-to-date document anywhere, describing how to create and integrate a new radio backend these days?

Only ask as I have acquired an Icom IC-R9000 for the shack, and would like to "integrate it into the fold" as it were.
(Hamlib knows of the radio, but that's not entirely complete, and is very buggy too, though it proves that the USB<>CIV device and radio work OK together.)

Any info re the above welcome.

For all you RTTY / Teletype fans out there, this is a fantastic video

Takes me back to my youth. School radio club was run by a teacher into RTTY. So I grew up from 11-18 on AR88, CR100, B40 receivers and Teletype models 14, 15 & 28s as well as British Creed 7Bs. We used US CV89A FSK units. The built in 1in scope made tuning noisy signals easier. As a kid I wanted to play with computers and solid state stuff but there no computers and most gear used valves(tubes) and radio and RTTY was the next best thing.

Teletype 28 was my favourite unit. We had 2 of them both KSR units. Plenty of TTY15 page printers and a complete TTY19 which was a TTY15 ASR unit and an extra tape TD unit on a metal table strong enough to take the weight. The PSU used a mercury rectifier so there was a light show in time to the selector magnets clicking.

They were all set for 45.45 baud commercial speeds and so we'd copy news output from behind the Iron Curtain, Tanjug and TASS being the easiest signals to copy. I can remember copying some class propaganda about "American imperialists and fascists" from an Albania news source. Even as a kid with limited understanding of world politics it was funny to read.

I last used a real Teletype in 1979, 45 years back. The last few years there has been a demonstration teletype running at the Friedrichshafen Rally. The smell of warm machine oil and the clackety-clack made me feel 50 years younger. That was a Siemens 100 which is similar in looks to a TTY15 page printer but quieter.

RTTY with a PC holds no interest compared to RTTY with a real TTY.

Very interesting, David.? I have a model 15 which I acquired around 1968 and used for many years here prior to the ubiquity of PC's.? The machine in the video described as a model 14 is not.? The model 14 was a typing reperforator usually with a rotary TD attached to transmit.. Because the paper tape was also used to transmit it needed holes, but if you had holes you could not read the print.? The solution was to punch "toilet lids."? The chad was attached to the paper tape by being punched almost all the way around.? I had one and let it go many years ago.
I will be happy to share any and all, as well a few stories about using the model 15 and it's quirks.

For all you RTTY / Teletype fans out there, this is a fantastic video taking the viewer through how a teletype unity actual works including details into Baudot 45, a full teardown and rebuild of both a typewriter style and ticker-tape style teletype, etc.? Great stuff and well worth your time:

??


This video comes from "Usagi Electric" who has made a lot of other great videos on building his own vacuum tube based 1bit computer, restoring various tube and legacy Mini computers, etc.?

The code corrresponds correctly to the CAT command descriptions.?? You can check whether the correct commands are being sent to the transceiver.? Open the trace panel and deselect all trace functions with the excepttion of the "set trace".? Press the "view trace" button.

Then open the pull down tab panel to the "extras" tab.



Select as above for the clock and then press the "Sync Now" button.? The commands should be sent at the 00 second instant.

The correct command sequences for selecting antennas are

AN01;? ==> antenna 1
AN02;? ==> antenna 2
AN03;? ==> antenna 3



to read the current antenna selection

AN0;

The response will be

AN010;
AN020;
AN030;

Note that the third and fifth characters are always a zero, not an upper case P or O.
