RF pollution is maddening! It ruined my evening last night during Run For The Bacon; and it reared its ugly head again tonight.
Last night I was able to copy all of two signals. The local noise was 10 over 9. I gave up after a half hour of pure frustration. Tonight started out a lot better. I was having a QSO on 40 Meters and the band noise was normal. Fortunately, it was at the END of my QSO when someone flipped a switch and the 10 over 9 hash came back with a vengeance!
I don't know what it is that is causing such horrendous interference. It's not anything in my house as the kids were asleep and my wife was working. I had nothing inside the house turned "on" that could generate so much noise. This noise HAS to be coming from a neighbor's house. A plasma TV perhaps; or a device like it?
It's not going to be easy to identify. Even harder will be explaining to the neighbor how his appliance is screwing up my radio!

Hello Larry: Perhaps you might want to look here, for help with interference:

VE3HLS’ RFI Noise Identification Page
I believe I’ve written before about the Digital Modes Sample page, but the RFI Noise Identification page was a new one for me. The page has 20 or more .mp3 files of various types of noise in the following categories:
Household appliances and electrical equipment
Computers and related equipment
Transmitters and intentional RF emitters
Electric Utilities , BPL and industrial equipment
Miscellaneous Equipment
I've recently discovered why dimmer switches have their reputation.
ReplyDeleteAll my equipment is located in a shop room in my garage. My problematic dimmer switch is located in the master bedroom, a room which is literally on the opposite side of the property from the garage. You couldn't put the two farther apart. If the switch is on, I get an S9 buzz on everything, everywhere.
This little dimmer switch is so bad that it even screws up the AM radio when I pull into my garage.
