Hi pitch buzz from autocom

[Dave78]

Hi guys, not sure if anyone has heard/seen this before

I've got a Autocom Logic, and has worked fine for the last year, both as a rider to pillion and from the last couple of days with a Midland G7 as a bike to bike.. The radio is being powered from it's batteries, as is the Autocom Logic

Then today, there is a high pitch buzz from the speakers, and if I transmit on the radio this buzzing noise is sent on to the receving radio as well.. It sounds like a fly but abit higher pitced

If i just plug the headset in (no radio connected) then it seems ok for about 20 seconds, then I can just hear the buzzing noise, if I talk so trigger the VOX then I get to hear me just, but mostly I get a loud buzzing..

I have just brought another Logic for SWMBO to use, and tried that, same result, I've got 3 headsets (the orginally two that SWMBO and I used as rider/pillion) and the new one with the new logic unit, all have the same issue.

I went out for a ride, and the problem was still there about 20 miles down the road..

The only thing I can think is it some sort of interferrence causing this, but it seems strange that it work fine on monday, but today it's rubbish.

Any thoughts..

I've had this a couple of times recently and disconnecting the headset lead and reconnecting has sorted it.

I don't understand how a DIN connector can get crossed up, but it almost sounds like that has happened.
