[RFI] New Noise - 160 Meters - SOLVED

[Joe Galicic]

I'm happy to report that I found the source of this terrible noise ! 


Although it was very random and only bothered me during parts of some contests I finally got tired of it and spent a week to find it.  Little mag loop antenna connected to K3 in my car.  Sniffed it out to two neighbors house.  


It was a Feit instant on LED light bulb screwed into an exterior garage door light fixture two doors down from me.  It only made noise when screwed into the left side garage light socket.  It was quite in the right side garage light socket.  It was a combination of bulb, socket and wiring.  It took about ten minutes for the bulb to start making noise. Neighbor has removed the offending bulb.  


Just to refresh your memory here is a recent video of this MONSTER.

It is very random in nature. It is not connected with weather or time of day. It will appear for a few hours or a few days. It has a unique looking signature on the band scope. It is very wide and moves around the 160 meter band. Today it is over 200 KHZ wide and its upper limit is at 1960 KHZ. Sometimes it appears below the 160 meter band and sometimes it's upper limit is low in the 160 meter band. Very odd ? This noise is only on 160 meters.
