Based on the garbled voice (scrambled) and beeps you're noticing, it's probably consumer FRS or business VHF/UHF radio which can range from 0.1 - 100+ watts output. Either a neighbor, or somebody several miles away, could be the culprit. I've heard CB radio through my gear, but am unsure if CB is using tones these days.
Picking up phone chatter
Frequently I can hear faint phone chatter and even beeping coming through my speakers when my systems on but not playing anything. It's usually one-sided (only hear one side of the conversation). Keep thinking it's a cell phone but there's really no one within 100 feet of my gear.
Don't know how to stop it. Any ideas what's going on?
