Got this great old piece of kit for pretty much nothing (€25?) and it's in completely working order save for one of the trimmers that adjust the narrow tone pair frequencies being a bit dicky, but that's workable around by simply setting those two tones a bit lower because they'll only ever be transmitted as SSB.

Had it decoding RTTY from 20 metres today, and the output seems to be fine as well, so hopefully should be able to get on air with it soon to do digital modes the old-fashioned way. Also shown: enormous manual because this thing runs on a Z80 and is entirely controlled by terminal commands. #hamradio
