I am seeing some QRM every 50KHz through the HF spectrum - it’s exactly on the .00 or .50 frequency, and I see it throughout the HF spectrum, but it’s really strong around 40 meters.
I know troubleshooting QRM can be quite a task, but this one is odd that it shows up every 50KHz.
Any ideas where to start?
Antenna is a 20m dipole in the attic connected straight to the rig via an 85 foot run of LMR400.
