[Elecraft] New Revision of KPA500 LPF TR Switching Rework Rev. E

[Petr, OK1RP/M0SIS]

Roy,

The modification can be done as prevent action in order to avoid the loosing
the full power (12m) accompanied by burning smell or it can be the solution
for
your already ruined amplifier.

The typical KPA500 misbehavior sounds like it is arcing inside and smells
the
classic something is burning smell. The SWR LED's are dancing upwards as it
arcs. If you have connected the KAT500 tuner then it has the SWR around
1.3:1... and power is lost.
