Guys, A friend of mine has a faulty TS930, details below. Are there any stock faults which he should look for first? Thanks, Eddie G0EHV (A happy TS-850 User!) TS 930S...No receive signals anywhere; both volume controls seem to be working. Transmitter is working normally. Signals can sometimes be induced by switching the power switch on and off rapidly. Recently this action has failed to bring results.
