[Today’s run: rest day]
I have a strong interference signal on 146.66x which I think is having a bad effect on my APRS monitoring station.
I cut a coax stub filter to null it out. That attenuated the signal but it also attenuated the whole band between 143 and 148 MHz. So, not what I want.
I’m thinking now two things: 1) I wish I would have kept one of those VHF cavity filters that I had last year (sold them all) and 2) I should install a radio in my car and drive around to see if I can figure out where the interference is coming from.
