First of all when I did get the bad IMD report on the

For testing, the K3 has the very excellent feature whereby it can
measure the receive voltage. That would be an FB way to compare
signals.
No it would not.The dBV meter is only useful on a constant and
steady carrier.

Oh I hope I can get a S9 from you also if my signals makes
it all the way to the USA.
Look for me in the CQWW, if good propagation I might be single
band 80m otherwise I´ll be moving around the bands, then you
will work another K3.

Forexample: A very simple fix is to use a OptoMOS relay. The
LCA110 from CLARE can key 350V 120 mA, cost seems to be a
little over 2 USD.

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