[Elecraft] KAT500 Auto or Manual

[Don Wilhelm]

Kev,

For your indication of high SWR when the KPA500 is in OPERATE, try 
replacing the coax jumpers with known good ones.
It is not unusual that a coax jumper (or antenna feedline) to seem to 
work at lower power, but can breakdown at higher power levels, 
particularly from a shield that has almost pulled away from the plug.
Also, make certain the PL-259 connectors are tight - snug them down a 
bit more with pliers.
