[Elecraft] KPA3 in K3S mostly not working

[Carl Yaffey]

When I get my K4 (hopefully May . . .), I currently plan to send in my K3S for repair. I have already talked with support.
The symptoms are:
1) In transmit mode, no power when raising the power above 11 watts. This happens about 90% of the time. So the 100w amp is not totally gone.
2) In receive mode, sound drops considerably when raising the power above 11 watts. This is, of course, coincident with the 100w amp failing.
I haven’t found anything that causes the amp to come and go. Seems random. In can be OK while sending and the suddenly fail.
Also, the transmit calibration fails.

Anyone have this problem? Is there a “fix” without sending in the rig?
