[Elecraft] KPA500 Power In Digital Modes

[Eric Norris]

Don't do it!  If you can't get an answer here, contact Elecraft support.  Your KPA500 will work great on 6m once you get this issue resolved.  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.
