Hey guys, first of all, let me apologize as this is probably my 5th post regarding my reception problems with a base scanner set up at my house. I've gotten lots of good info and tried lots of things, but haven't been able to resolve the issue. Then today I found an old post from someone having a similar issue as me. He posted a recording of the interference he was getting. It sounds EXACTLY like what I am hearing on weaker signals. That interference was tracked down to a transformer in front of the building he was in. Power line noise! The one thing I hadn't really considered but would explain all the issues I'm having. If there is an issue with a line or transformer in front of my house, it would explain why I have the same issues regardless of scanner / antenna combo, coax length, connectors, inside or outside my house, etc.... And it would explain why I still had the issues even after turning off the main power breaker in my house and running the scanner on batteries. It would also explain why reception improves just up the road from my house.
Here is my question. Can power line noise also cause a loss of reception? I know it will cause interference and noise, but my issue also includes a loss of reception of signals I used to get fairly well. For example, there are signals I used to get clearly. Then for a while, maybe a month, I would get those signals clearly sometimes, then not at all other times. Now I almost never get them at all. Like the power line issue was intermittent at first.
Quick tip: Once in a while the signals that are scratchy and noisy come in crystal clear all of a sudden, like someone threw a switch. Then just as quickly, the noise would be back.
Another tip, the issues I'm having are in the VHF High public safety range (150's). Anything I scan in the 400's seems to be ok. I don't scan anything lower then the VHF High range. Thanks again.
Just curious if I might be on the right track here before I start trying to track down the source. Thanks guys, the help is much appreciated.
