I'm in Gawler area and don't pick this up. Could be local interference?
This could be a form of AQAM. If you zoom in closely youll notice the way the carrier is, being FMFrequency Modulation with angled sidebands. Now I dont know what this form belongs to as far as this one is concerned. Some forms of AQAM also sound like a fax machine if it produces nothing but noise. --Ywsia (talk)
RE: Nknown 472p875
I have the same interference on VHFVery High Frequency (30-300 MHz) from around 160-165 it gets worse near 163-164 the signals are all so strong it wipes out other signals.
I am convinced it is local interference from something but for the life of me i cannot figure out where it is coming from, I have tried turning my power off in my home so if it's something inside my home it should have stopped but it still there.
I have also walked all around my home with a handheld transceiver and the signal does not change or fade in and out.
