:mellow:Im hoping someone can give me some advice on this one..
i have a president lincoln wired in my car. both Linear RM KL200p (100watt) and radio run directly from the battery. on the roof of the car is a Sirio 4000pl
Every time i go to key up the microphone (Astatic Minitueman) i get nasty RF burns off of the metal parts of the microphone. it really hot with or with out linear, of course its worse with the linear but still burns with out it on 5watts.
can anyone point me in the right direction at all? when i use the radio in my house on my homebase powersupply and same microphone and same linear amp i get no RF burns at all.
could this be something to do with grounding of the radio unit? or could it have something to do with the grounding of the Antenna on the roof of the car?
Hope someone can help me!
Cheers
