[Elecraft] KPA500 - Full Power Keydown

[Harry Yingst via Elecraft]

Agreed 
I'm looking for people who actually run it at 500 watts in SSTV, or other like modes (not voice)
A SSTV picture can take 110 seconds (Less or more depending on encoding, but 110 seconds is common as Scottie 1)

All of this anecdotal eveidence is interesting but meaningless.

Elecratf advertise and rate the amp as a 500W amp. Not 600, not 700. Someone should put the amp on an spectrum analyser while running at 700 wats to see whatr it looks like while being overdriven.

Elecraft have also said, in the operating manual, that the time limnit is 10 minutes key down. Did they put that line in the manual just to take up space or is it purely CYA?

Jusdt because some people are overdriving the amp and getting away with it doesn't mean it was designed for it.
