in the line and does the
calculation for power. Thus these are more accurate over a range of
load impedance variations.

Thank you all for the suggestions and encouragement. I am optimistic that it is
now fixed. I believe it was one of the TMP coax plugs that had a faulty
connection. But by shot gunning fixes I cannot pinpoint that specifically.
Below is the long story:
Earlier I had replaced the wattmeter
Hi Chet;
You should be able to run the TX gain cals with no errors, otherwise
something is wrong.
NOTE; After a successful Gain-Cal, then never, ever, TX at exactly 5 or
50watts (or 1.0MW) as that can cause an inadvertent TX gain cal and mess
it up.
To me, it would appear the LPA is weak.

It sounds like you do not have sufficient audio drive.
In DATA A mode, how many ALC bars do you obtain? You must have 4 bars
solid with the 5th one flashing.
Adjust the audio levels from the computer to achieve that - I assume you
are using LINE in.

My K3 transmitter has been struggling for months to behave. I've heard the
service dept turnaround in CA is very long so I might not see it the rest of
the year if I sent it in and wanted to avoid that if possible. I've followed
advice suggested here with no lasting success.
Especially on 6M
