[Elecraft] Re:Problem with KPA 100 (no power selection possible)

[Gregg R. Lengling] what you need to look at is the SWR/Power bridge circuit
in the amp.  I had a lightning hit that screwed up my amp and caused it to
always be full power and it turned out this is the circuit that caused the
problem.  The VRFDET line is used to control the output power of the unit,
it needs to be able to see if requested power = delivered power.  So you
have a problem there.  This is where you start.
