Phil,
I had the same issue when I hooked up an SB200. Because the keying
voltage in the amp is negative, you can't connect to the K3 directly. I
put in an intermediate relay, which works OK. I might install the
Harbach "soft-key" mod at some point...
Have you put a continuity tester across "KEY OUT"? So long as you
connect the positive side to the center, it should only read closed
when the K3 is transmitting.
