[Elecraft] KPA500 Power In Digital Modes

[Michael Eberle]

Yes, I suppose something may just need a slight adjustment.  It just 
frustrates me when things don't work like I expect them to.  I was 
always afraid to run JT65 at more than 80-100 watts until I saw this 
post.  Started trying higher power while keeping a close eye on the 
temp.  No faults on any band but 6M if it gets much over 200 watts (8 
watts drive).  It seems to be running 450 watts easily on 160M.

Mine runs at 600w on 6m meteor scatter using FSK441 30 seconds on, 30 seconds off, for hours on end, hitting 65C but soldiering on without complaint.  That would leave my former dual 3-500Z amp squeaking from the freaking.
