[Elecraft] KPA100 problem

[John A. Magliacane]

Hi Dave.

If you're running 2 watts, the KPA100 is bypassed and the only thing
in use is the KPA100's low-pass filters.  If there's a problem with the
filters, or an associated relay, I could see where that would cause a
high SWR and produce a "Hi Curr" warning.

I suspected a problem with the filters in my KPA100, so (lacking any
better approach) I fed a Uniden HR2600 10-meter rig (with internal SWR
meter) into the RF input of the KPA100 with the K2 on 10-meters and
the KPA100 bypassed.  With the output of the KPA100 feeding a 50-ohm
load, the HR2600 showed no reflected power, so I knew the filters
were okay on 28 MHz.

Just a thought...
