Check your antenna for improper ground or poor coax. Cheap coax has poor insulation. Also those Firerings from firstik are ok but they still are not the best for a good ground and connection to your antenna. Also if your SWR is high the power is being reflected back to your CB and it is finding any way out of the radio.
also make sure the head unit or any amps have a nice heavy ground to them.
So those are a few things I would check for, A nice solid proper ground on your antenna. Good Coax. Copper electronics sells RG8 mini for .23c a foot. and they sell the coax connectors for a good price as well.
Just remember if your radio causes any interference by I think its fcc law part 15 its your duty to make sure your signal does not interfere with any device. Not meaning to sound like a party pooper or anything of the sort. Just hate to see anyone get nailed for something.
