Dave, Looks like you have pointed me in the right direction. I had not done the wattmeter calibration as the manual implies that it is optional. That plus the usual inaccuracies in the average wattmeter I decided to accept the factory settings. This morning I did the procedure and thus far have not had a high current warning. Current is 1-2 amps less than before; still a little on the high side but at least no warnings about it. Knock on wood......
For the Elecraft tech writers and anyone attempting to do the procedure there is an error in the procedure. On page 49 of the Owner's Manual the last step on the bottom left should read tap XMIT rather than hold TUNE. If TUNE is used rather than XMIT the radio will output 20 watts regardless of the power set while calibrating. Thanks for the help. 73, Jim, W0EM Dave G4AON wrote: > > Jim, if you calibrated the K3 Wattmeter with a low reading Wattmeter it > would give the symptoms you describe.
