I think I know what you mean. Shows us as a very brief, repeated disruption 
to PL tone, drops your mobile/ht decoder, maybe for time in 2 seconds, then 
ok for a while. t iunterrupts main audio as well, just very brief and not 
noticed.

Yup, every PC I tried does it. I jusst got used to it.

I wanted to get a recording of it over a year ago, but no clean way to 
record audio. You really get to notice it if you put your signal generator 
in the receiver, and modulate with something like a 1Kc tone

I've tried five computers and four USB devices, all do it.
