Barrie Posted September 1, 2020 Share Posted September 1, 2020 Dear All, I have a 320 man pack which has obviously seen better working days and would like to get it working again. When switched on, with a fully charged battery, it emits a continuous high pitched whine.. There is no receive or transmit. I don't feel confident enough to delve into the inner workings of the 320 so was looking for recommendations for a person / company that will do repairs on the 320. Thanks in anticipation.
