[Elecraft] KXPA100 Low Receive Signals

[Jim GM]

OK what do I need to change on my KX3 Menu?

As I increase power from 4 watts to 100 watts I hear a series of clicks one
at 5 watts and one at 10 watts from the amp. Each time there is a click the
receive signal drops like an attenuator.  The attenuator on the back of the
amp is in the OUT position.  What do I have messed up now?  What do I need
to change?
