Dan,
If you tested your KX1 into a good 50 ohm dummy load, the indicated power
should have been within 10 or 20% of the correct power either with the KX1
in Cal, or in Tune if you do an ATU tune.
If you tested it into a resonant 50 ohm antenna, then the reading should
also be correct on that

It also works wonders to filter out loud PSK31 signals that are

Actually, CW is legal on 60m, you just have to center your signal in the

rule language says, at least yet.

Actually, since March of last year, CW, RTTY and data are now allowed on the
