NOISE IS BACK! ALL 40 CHANNELS - Suspect BUG ZAPPER
Sad but true. Hello all, I've been working massive hours at my job all summer so I have not had any time to get on the radio. As most of you all know, I had a really aweful interference buz coming through my radio speaker. A year ago, I suspected the neighbor woman's bug zapper that she kept on all summer & all last fall into the early winter before I saw that she had turned it off. I thought it was her underground supply power lines from the pole in the alley going to her house. But it's not. Many of you have read this entire thread. But if you havent, I suggest you do before replying. I thought it was something in my house, it was not. I have turned the radio on from time to time, but I always use the noise blanker & the ANL to lower the interference. I also have been using the squelch, so most of the time I have not heard the noise.
As I mentioned, I have not been on the radio much this summer, so I turned off the ANL & the NB, and the squelch. And lo & behold the damn noise is still there. A loud constant buzzing on all channels. After months of investigating, I thought I had solved the problem as the power company replaced her underground power supply box that feeds her house. What a fool I was to think I was free of this horrible AC hum.
Now I am back to square one. I believe it's the neighbors bug zapper. She has it on again. It's in her garage & I can see the purple glow through her garage window. She has had it on again all summer, but I never made an effort to see if the noise was still there. I also know that this EMI inteference is coming through my antenna and not my house mains. I have used an AM transistor radio with a telescopic antenna & nothing in my house but a dimmer switch makes noise.
When I point the AM radio antenna towards her garage which is only 20 or 30 foot from my shack, I can hear the interference. Does anyone know of any device that will filter this airborne broadband EMI from her zapper from coming through my antenna? I have an IMAX 2000 vertical. I also know that verticals will pick up the frequency waves from offending devices, especially a bug zapper. I have also heard that horizontal antennas like a beam will let the offending frequency pass through because of a beam's horizontal position.
I'm not ready to slap down $170.00 for a beam, just to see if the noise goes away. So I just wanted to know if anyone out here knows how I can filter this from coming through my antenna? I do not get along with this woman either, so I can't ask her to turn it off. Am I SCREWED? Please help if you can. I can't stand this noise. I'd move if I could, but that's not an option either. :headbang
