Hi all,

I've noticed a strange buzzing noise every few seconds on my feed: Hancock County Sheriff, Fire and EMS, Greenfield Police Dispatch

My assumption was it was interference from a power supply of some sort, so I've tried eliminating different devices that are in the same room with my scanner and the Raspberry Pi I'm using to provide the feed, but haven't been able to find the source of the noise.

I also swapped out the power supply to the Raspberry Pi, but that didn't fix it either...

Any thoughts/suggestions on what to try next?

Thanks!

My guess would be a ground loop somewhere along the circuit. Have you tried any kind of inline noise suppresion devices? The name escapes me right now but I know its some sort of isolation transformer designed to eliminate ground loop hum.

I know one of my computers has this issue. I got a pyle hum eliminator and no more hum. About $15 on ebay I believe.

My 2 cents. Probably all its worth LOL!
