KPA500/KAT500 and RTTY

[NK7Z]

Hi,

Any recommendations as to the max power I might run using a KPA500 and
KAT500, on say, a three to five minute transmission?

Also, what is the recommended max temp for the PA on this device as
measured by the KPA500?

Dave,

I have done many RTTY contests and regular qso's using the
KPA500/KAT500/K3 over the last few years. I run full 500 watts with no
problems, the temp gets up to the 60 to 65 range a lot when calling CQ
in a contest, or during a 10 minute tx.  If the temp gets to 70 then the
fan kicks into high gear and is very noisy, but still within specs.
