Got a old Cobra 2000 GTL late 1978 model. Been fully electrolytic recapped. It has a low air blowing sound coming through the speaker when the volume is turned all the way down. I attached a video explaining this issue with it. The sound is still there even with squelch turned up and rf gain fully counterclockwise. The 2000 used to have a roger beep board in it. I removed that and corrected the wiring to the mic jack but maybe I have the wiring wrong cause this problem. It used to receive with the mic unplugged. Thanks for any help or suggestions.
