Mike,
You can use the KPA500 on AM at the full 500 watt rating.
BUT remember that the power is Peak to Peak.
So you will not get 500 watts of carrier and a total of 500 watts of
sideband energy. You will get 250 watts of carrier and 125 watts of
sideband energy in each sideband - for a total of 500 watts PEP.
If you are long-winded on AM, you should reduce the power - check the
temperature.

I know the KPA 500 is designed for SSB and CW, but I have always wondered if
you can use a KPA500 on AM and, if so, what would be the maximum wattage you
should use? The manual
doesn’t say anything about it. 73 Mike KF6KXG
