Harbor Freight has a cheap solution. A 2 lb ball peen hammer will take care

[Chris Medlin via BVARC]

It definitely IS the responsibility of the neighbor but most do not understand 
the part 15 label on their stuff, it ends up being on us to explain it.

I would agree that as hams we try to help out neighbors who are causing 
interference to licensed stations, but in the end it is the 
responsibility of the neighbor using a Part 15 device that is causing 
the interference to find a remedy. I know it can be touchy when we want 
to maintain good relations with our neighbors, and I'm sure there is a 
solution to reduce the interference.

When I got the email there was a winmail.dat file attached. No jpg was

Re: [BVARC] Recommendation for noise suppression?

[Amal Phadke KT5AC via BVARC]

Thanks a bunch for the quick replies. 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?

 

Thanks,

Amal – KT5AC

I had an issue with noise recently and it was caused by the proximity of my

I have only seen something close to this level of interference on 2m and
that has been from some cheap LiFePo4 charger I got that was charging my
100Ah battery. 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
