Amateur Radio use of old 8-bit machines

Post by Seldon2k » Wed Dec 11, 2013 9:45 pm

Hi All,

I wonder if anyone has used a UK101, BBC Micro, or other even rarer machine for communications purposes?

I first used my UK101 on CB to transfer files to someone about a mile away, this involved some simple interfacing to the cassette port on the 101's.
I then wrote a simple basic program to send and receive ASCII text between us.

When I became licensed my BBC Model B was used with an RTTY interface and the G3WHO ROM,
I also recall using other software with this possibly by BMK.

I also used a 48k Spectrum for SSTV (Slow Scan TV).

More later as I recall them or discover my old paperwork.

Terry.

OK strictly speaking I should not be adding this link but I have just been made aware of it.

That's one from Dave, (Hoglet), and shows a an old 1980's RTTY interface complete with circuit diagram, code and messages received on his BBC.

I am very interested in both retro computing, and, something called retro QRP.

QRP is Low power amateur radio.

Here are some interesting links:-

I used to use my Beeb to receive radio teletype (RTTY) transmissions. I made an interface using a phase-locked loop circuit from, I think, the 'Radio Hacker's Code Book' and connected it to the user port. I wrote the decoding software in pure BASIC and it was fast enough to keep up with 50 baud RTTY. I was amazed! This would have been in the late 1980s, and I remember receiving all sorts of strange things. The USSR news agency, TASS, was a prominent broadcaster, and I also picked up lots of mysterious encrypted signals with groups of five figures going on apparently endlessly.

It was a lot of fun, but I don't think there are many RTTY signals out there any more. Shame.

I have just found an advert for RX-8 for the BBC Micro:-
It is too big to upload so here is a link to Google Drive:-

Hope someone finds it useful,
