Hi.? There's probably a simple explanation/fix, to make me feel stupid, but I'm having some trouble with my Winlink gateway.
As it scans from 80m, 40m, 30m, 20m, 17m, the audio input jumps from deep in the yellow region to touching the red zone (-45db to -7db).
It is low (-45) on 20 & 17, and high (-7) on 80, 40, and 30m.
Since it varies with the band, I suspect some kind of rfi(?), but it's high or low - no in-between.? Also, I don't know what kind of rfi would affect the Windows 11 audio levels.
I have ferrites on all the cables in/out of my micro-pc.
Please provide me an "aha!" moment.
