Lots of neat SMB cables route lots of unknown RF signals from one RF PCB to another. Opening the box, I was pretty fast persuaded that I'd have to find a service manual before attempting to repair anything: ![]() See if I would be able to repair this thing.

So now I was the proud owner of a pretty useless Radio Test Set, since none of the RF functions worked. Baseband audio analysis worked, using the baseband signal input.A quick check in generate mode showed that there was some kind of a signal at the gen out port, but neither of the expected frequency nor amplitude. ![]() When the self calibration finished, there were no error messages and I was able to play around with the various menus and settings.The unit powered up running a quite lengthy self calibration procedure.After receiving and unboxing, I've learned pretty fast, what Its description said something like "I've tested a little bit of the functions, which appear to work, other functionsĪre not plausible to me. ![]() ![]() Motorola R2600B R2600 Radio Communications Analyzer Repair or how to jump start with RF electronicsįor no particular reason, I bought this particular pretty looking piece of electronics at our favourite electronics scrap yard
