[RFI] What Possibly Is This RFI??

[Stephanie WX3K]

Hello Joe

I understand your frustration.

Some points to consider on your second visit through the home.

1) killing the main breaker in the house may not un power certain devices that have battery backup

2) make a quality video clip using your cellphone with the radio in AM mode and the bandscope in its widest span setting. Share this when asking for assistance.

3) what band is worse ? 

4) can you listen to the RFI on a band that allows you to get a general azimuth where the RFI peaks up

5) is it possible to hear the RFI on 6 meters ? I personally use a set to TV rabbit ears with a balun hooked to my portable radio/receiver and walk around the neighborhood to find where the interference is the strongest. 

RFI can come from so many different sources. It may be even from multiple sources.

Powerline RFI is common but not always the case. A 120 Hz buzz character is a clue for power line noise.

Go to YOUTUBE and look up Mike K3RFI. He has excellent videos on chasing powerline RFI.

I have spent MANY countless hours chasing RFI over the years. Its worth the effort to MANAGE your noise floor. Please do not give up by turning off the radio and walking away.

And remember the most important aspects of dealing with your neighbors, respect and communication !

Good luck
