Ed,
For the future, consider your antenna situation carefully. When the
station is not operational, all my antennas are grounded (via relays)
and the K2 is connected to a dummy load. I do have an extensive
antenna switching
Don,
You were spot on. The SWR Bridge diodes D16 and D17 had failed. The
diodes arrived today in the mail, I replaced them and my K2 is up.
Thank you very much for your help.

When the KPA100 is not installed, my K2/QRP operates normally.
However, with KPA100 installed I have no incremental power control and
no lit LEDs on the K2 S/RF meter.
The SWR is indicated to be 1:1 into an OHR RFL 100 Dummy Load. HiCur

Ed,
Lack of power control with the KPA100 installed normally points to a
failure of the KPA100 wattmeter circuit.
Start with replacing the 1N5711 diodes D16 and D17. It could also be
that U5 and/or U6 are not performing properly.
If your KPA100 was working at one time and there is *any*
