Mike,
The K2 RF gain is higher on 80, 40, and 30 meters. It takes a bit more
drive and current on the higher bands.
Have you verified the power output of the base K2 with the KPA100
removed? That is an important parameter to investigate.
After verifying that the base K2 is capable of putting out 10 watts or
more with the KPA100 removed, put the KPA100 back in-line and with power
only to the base K2 (no connection to the high power voltage), what is
the power output of the K2 with KPA100 - this is a test of the low pass
filters in the KPA100. The power output should be about the same.

I didn’t have ring connectors big enough but I did have spade connectors. I
crimped and soldered them but there was no change in the voltage readings
during receive and transmit.
Is it possible that the power supply is failing?
Why, if the voltage drops during transmit to 11.6V, does the radio still put
out 100W on 30, 40 and 80 meters?
Thanks,
Mike NJ2OM
