[Elecraft] K3 Power Problem ??

[Dave G4AON]

Jim, if you calibrated the K3 Wattmeter with a low reading Wattmeter it
would give the symptoms you describe. The calibration is optional and
calls for an accurate Wattmeter, the K3 already comes calibrated from
the factory. You might have a fault, K3 Support will be able to assist.

I use the supplied cable and obtain good correlation to the expected
power at 5 and 50 Watts, but slightly less at 100 Watts. There is a
table of the results at: http://www.astromag.co.uk/k3/

I've never had an over current warning.

73 Dave, G4AON
K3/100 #80
---------------------
Exactly 100 watts set on K3. Measured about 90 watts out on two external
watt meters. One on an MFJ antenna tuner and the other is a high end MFJ
power meter. They agree within a couple of watts near 100 watts measured.

Have a good day and 73.
