Benny;
Are you using an external speaker with the radio? Does the speaker
have it's own ground return to the power supply? I found this
situation on a FT-900 and discovered that a ground loop can damage
the audio output. Make sure both speaker lines are kept away from
grounding except at the radio. Good luck.
