Thank you. Some experiments:
does this happen:
- at a minimum TX power? - yes - at 20W - but less often
- with dummy load? - yes - but less often
- with different power source? yes
- with voice transmissions? yes - but less often
?
The ¡®less often¡¯ - is still often enough that it isn¡¯t useful.
My rig is in a travel trailer - currently the antenna is a mag mount vertical on top of a water pressure tank. 'No grounding' per se. But had been 'fine' for the last 3+ months at least in current location.
