My Bad.  It seems it's pretty tricky to make a really trustworthy =
wattmeter.  I knew I'd calibrated the full scale readings on my Oak =
Hills WM-2 pretty carefully but I didn't notice or had forgotten that it =
is about a dB low at the lower end of each scale.  I plugged my KX-1 =
onto an HP 8563 spectrum analyzer and measured 3.8 watts on 40 and 30 =
and 3.2 watts on 20 all at 13.5 vdc.  These are numbers I'm quite happy =
with.  Last night I installed the 30 meter and tuner modules.  That sure =
did kick up the 60 meter sensitivity and the tuner always seems to match =
the suggested 24 ft. wires perfectly.  Sorry I cried wolf about power =
problems but it's pretty interesting that no one came back and said they =
had a similar problem.  I think the design must be pretty solid.
