K3 TX problem

Jan Erik Holm
Power can not be set, jumping up and down and all
over the place, also at some power levels I do
get a oscillation sound from the radio.

So I tried to do TX GAIN calibration but no change.

Then I continued with Wattmeter calibration. Both
at 5W and 50W wattmeter can not be calibrated. I
adjust the menu parameter all the way up to 180
and power is still too high, about 7W (5W) and
60W (50W). Seems to me something is wrong with
the wattmeter.

Help please. CQWW is soon.

Did some measuring, it looks like one of the
diodes in the SWR bridge is faulty. Will
replace tomorrow.  Thanks to K5ESW
