Just got around to trying to put a KWM-2A I bought a few years back
on the
air. It's in roughish condition, but seems complete and usable. After
replacing a failed diode in the power supply, it recieves fine.
I've been trying to transmit, and there seems to be a problem. It
tunes up
OK into my dummy load - the power meters in the dummy load indicate RF is
flowing while it's in the LOCK mode. When I try to transmit using the PTT
microphone that came with it, the relays clack when I key it, but...no RF
out. I'm wondering if this is a common problem - anyone heard of it?

Try swapping out V1 the first audio amp as half is used for the mike
audio and the other side is the tone oscillator. It is possible to to
have rf out on tune up, but nothing on ssb.
Also, there are a couple of low voltage electrolytics in the microphone
stage that are always bad after this much time.
