ERR TXG

[Eric Merlen]

Good morning folks,

I assembled a K3/10 + KBPF3 + AM filter (+ default 2.7Khz filter). After
synth calibration, filter setup, ref oscillator calibration I performed TX
gain calibration using Electraft K3 utility, but it fails immediately with *ERR
TXG*.

Filter setup is
Fil1: none
Fil2: 6.0Khz (0hz), 0db
Fil3: 2.7 (-0.85Khz), 0dB

Any idea of what the problem could be?
Thanks

Have you tried starting with a different power level setting on the
front panel control? I've had a similar problem and that fixed it.

Alternatively, have you tried manual gain calibration?

Make sure you have set the 2.7K filter as the TX for all modes where it
makes sense.  (all but AM in your case it would appear)

Hi Dave,

yes I have tried starting with a different power level setting on the
front panel control.

The manual gain calibration doesn't work either. The power output measured
is always 0W regardless of the power level setting on the front panel and
SWR meter shows '--'

Thank you

Hi Bret,

Thanks for the suggestion.

I confirm I set the 2.7Khz  filter as the TX filter for all modes but AM
where the 6Khz filter is used.

I left FIL1 slot empty as I plan to add an FM filter at some point (and more
filters for CW/data) later, but according to the manual, that's fine to do
so.

One think worth mentioning: I had to apply significant pressure on the
three  transistors mounted on LPA board when I installed the lower bottom
panel because the transistors raised slightly above the bottom panel level.
I don't know if it is normal (ensure good thermal contact?) or if I used the
wrong screws somewhere.

Reseat the antenna board or tuner board and make sure you have the SO239
connectors plugged into it correctly...?
