yes and moved that around to see if that was it and it's not a scream or feed back. it's when you key the mike and it has a whirl,but if you hold the mic wire and touch the radio it gets less and thats what makes me think it is rf. |

how about changed or added finals, or something that altered the chassis' floating ground? or some other add-on not properly grounded? the chassis is not normally grounded to the dc ground. |
