This is probably not the answer you want to hear, but I have heard of stories like this and the answer has always been that the ham talks to the neighbor and ends up purchasing an equally good product that serves the same purpose that does not cause interference. Or… best case scenario, the ham goes in 50/50 with the neighbor on a product that does not cause interference. Find a way to make it a win/win situation. The ham radio community is a friendly diplomatic group. Back in the day when people were watching analog tv over the air, many hams had to educate their neighbors on the use of high pass filters to keep our interference out of their tvs. Now with LED lights and cheaply made ballasts in lights, we are dealing with interference in our radios. Good luck and 73. Chris/AC5CM

Through a truly bizarre coincidence, I can confirm (99.9% certainty) that the RF noise was from my neighbor’s outdoor soffit lighting. What happened was, a few minutes after I sent my original email about the noise, I went back to my shack to check the radio. Lo and behold, the noise was gone. I peeked through my window and saw that my neighbor had turned off his soffit lights! That was an unbelievably strange coincidence! The question now is what should I tell my neighbor to do to stop the interference, other than to never turn on the soffit lights 😊 Any suggestions?

You may want to start turning things off to see if you can eliminate the source of the noise.

But it was about 25% bars and it was about 30ft from my 2m antenna. It does happen a lot with chargers for various batteries like shop tool chargers etc. Sounds like a job for a 2m Yagi and am attenuator. I've got the Yagi but not the attenuator. 73, Kori Rahman, WX5KR Brazos Valley Amateur Radio Club Vice-President and Club Call Sign KK5W Trustee Cell: (770) 298 8516 kori...@gmail.com<mailto:kori...@gmail.com> On Sun, Jan 14, 2024 at 7:30 PM Amal C.

I suspect it is from my neighbor’s external soffit lighting, but I am not sure. The receive signal meter fully lights up like seen in the attached picture. The repeater was idle when I took this picture. It doesn’t happen on UHF, only VHF and only from dusk to dawn. I hear a lot of static in the received signal, and I suppose in the transmitted signal as well. Moving the permanently installed outdoor antenna is not practical and using slip-on ferrite beads on the coax didn’t help. Has anyone experienced this issue? I would appreciate any suggestions.
