Dave,
That sounds like the behavior of an unsoldered or poorly soldered
connection that is heating when you transmit. I don't know where to
tell you to start looking, but if you want to shorten the search, you
might be able to tell something from the Transmit Signal Tracing steps
in the back of the manual. It has a chance of leading you to the
failing stage and then you can examine that stage in detail.
Alternately, you can reflow the soldering over the entire RF Board with
a hot (750 degF) iron and dwell on each connection long enough to watch
the solder melt and flow.

One little glitch . To set the output power , it sets properly , say at
4.0 Watts , with the WPM +/- buttons , but after a few seconds
it dribbles around and goes down to 0.5 Watts or whatever.... Tweaked the
cans on the Filter Board but still NG . Wonder if others have
experienced this anomaly. Dave W1DWZ RI
