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
Dan,
With a 13.8 volt power supply and working into a good 50 ohm dummy load
(without the KXAT1 installed) you should have at least 3.0 watts on all
bands (I normally expect 3.5 watts or more). Measure with an external
wattmeter that is has known accuracy at low power - many wattmeters with
What a wonderful source of help this group is!
Turns out the problem wasn't really a problem at all. I was loading a
long-wire antenna when doing the measurements and relying on the watt meter
provided by the KX1. As Don and Rick suggested, when I connect a 50 ohm
DL1 dummy load and use a DMM
Finished a brand new KX1 this afternoon, with ATU and 3080 module.
Power output with 13VDC for all bands is as follows:
80 6.3 watts
40 1.7
30 4.0
20 3.0
Clearly something is amiss with 40 meters. I read somewhere to mess with
the green windings of L2 on the 3080 module, but that didn't
