[Elecraft] KPA500: Bonehead Input Overload

[Andy Durbin]

"That is a very good argument for having ALC active between the amp and radio. "

ALC is just another reactive protection.   In my station the KAT500 is commanded to inhibit the KPA500 key line by default.  Only when all required conditions are met is the key line enabled.  Enabling conditions include Hi_SWR false and TS-590 power set and verified.  Set drive power is not allowed to exceed 120% of band max drive power.  (That overhead allows the psychological boost of turning the wick up when chasing needed DX but prevents doing anything too stupid.)
