Hi Chris,
I was using my K3 and a small diameter magnetic loop antenna sticking up
through the sunroof of my car. I've found noise sources with this setup
before.
I can hear CW and FT8 signals on the loop but cant hear the RFI "signal" on the
loop. I thought this was very odd since the signal is pretty strong on my
shack radio.
One of my neighbors about .5 miles away has a new solar installation. I drove
past that house and it was quiet.
We don't have powered channel markers in the lake.
We do have lots of gulf carts around here so perhaps this is a battery charger ?
Thanks,
Joe
