Works fine at home and loses it's mind at the contest location with
different antennas, feed lines, etc....
My first impression is an RFI problem at the contest location.

Hello everybody,
I have a strange issues in my K3. Maybe someone has had similar symptoms and
may help me...
chronology of my actions with K3
- from the begining K3 was never opened, worked fine.
- 2015-06 - KXV3 installation
- 144 QSO made in this period time - no issues.
- 2015-12-31 Last firmware upgrade (5.38/1.25/2.86)
- 26 QSO made in this period time - in January - no issues
- SPDX contest (2016-04-02)- in my contest location - first operational
problems.
During the contest I have made about 40 qso.
Many radio restart have been made to be able to work at all...
symptoms: when I have pressed mic's PTT, TX led switch ON but there were no
power output.
The same situation was when I have used footswitch or playback message option.
After few pressing of the PTT output power appeared.
Next point was the AUT - time of the tuning was tottaly differen between next
tunes.
Next point - AF gain controls for main receiver.
Radio was not reading the knob position to change the volume.
Band change removed this issue for some time.
- Home station - 2016-04-10
Previous problems disappear, now i have a problem with the K3 power off.
It's look like not complete internal procedure.
whole firmwares were reloaded - issues still exist.
configuration was restored from 2015-08 - issues still exist.
Older firmwares were downloaded - issues still exist.
Actual firmwares were downloaded with last saved configuration - issues still
exist.
- next point - when I switch on my Diamond power supply - K3 power on
automatically.
