[Elecraft] KPA500 in the RTTY Contest

[Sebastian, W4AS]

I run mine on 6 meter meteor scatter at full power all the time.  Sometimes for up to an hour continuous (30 seconds on, 30 seconds off).  I have mentioned this to Elecraft and they didn't have any concerns about it.

I seem to remember, during the KPA500 field testing, that Jim, K9YC, was told to run his at 700W in a RTTY contest and it did it just fine there too.  Difference between 400 and 500 is less than 1dB, and to each his own of course, but I think the amp is more robust than some may think.
