[Elecraft] AM power for KPA500

That will be the same ratio as always, set by physics instead of the
manufacturer: carrier set for one quarter of the PEP rating.  That
would be 125 watts carrier for 500 watts PEP.

It always seems to be too small.

In the old days of the Johnson desk kilowatt, that was 1 kW carrier
INPUT, with a usual 700 to 750 watts carrier output.  With voice
processing, that was a well modulated 3kW PEP output.  There was a
reason those guys always sounded so loud, and for how heavy that rig
was.

My AL1200 needs about 30 watts carrier to transmit the max 375 watts
carrier.  Just about what my Ranger will do.

73, Guy
