This is just more of a question out of curiosity, since this isn't my problem to fix.
Several of the local school bus company radios transmit these weird squealing sounds while the drivers are talking. These sounds are usually quiet, but can sometimes be louder, and the pitch of the squeal sometimes changes as the radio continues to transmit.
The company uses a large mix of TK-8150, TK-8180, and NX-800 units on conventional, but I think it's mostly the older TK units that make this sound. Something's obviously not right with these radios, but I'm just curious as to what, exactly. Is it the radio itself? Microphone or microphone cable? What would be a solution to this problem?
While I was recording some transmissions in December, I caught one of the loudest examples I've ever heard of this sound. I just uploaded it to YouTube so you can hear what it sounds like.
