[Elecraft] Extra Protection For KPA500?

[Rick Bates, NK7I]

While you're adjusting the output drive for the amp on each band; make 
sure it's EACH band, including 60M (100 watt limit in the US) and 30M 
(200 watt limit in the US).

Yes, those bands also, because operator error (fatigue, excitement, 
rush, brain slip) WILL happen and having those QRP bands preset in the 
amp could save you grief.

Hope for the best, plan for the worst; this is planning for the worst, 
stuff happens.

73,
Rick NK7I
