Igor,
Try doing the TX Gain Calibration manually (described in the manual).
It is a bit tedious because it must be done on a band by band basis.
An email to supp...@elecraft.com may get quicker attention than the form
on the webpage.

My K3 S/N 1651 has developed a problem showing ERR TXG message from time

In fact I think these are two separate unrelated issues, but I might be
wrong.
TX gain calibration fails for 5 W (does not go above 4.5W) and works OK
for 50W everywhere but on 28 MHz because of high SWR.
I have filled in the tech support form on the Elecraft site about a
week ago but did not receive no response. I understand that is
associated with COVID problem. So may be someone on the reflector can
advise me what to do. Sending the radio back to the factory is not an
option.
