I am having an issue that I just can't sort out....i have 2 VHF radios in my Kenworth and both have the same issue, whether i have either radio on or both at once. The indicator bar that shows I am sending or receiving are both bouncing around endlessly when I am neither sending or recieving. I have installed new supply power wire and ground, new coxial cables on both units, new antenna coils on both and substituted another radio as a test and still the interference and very poor range. I tried a capacitor to see if RFIs were the cause but it did nothing. It makes no difference if the truck is running or the key is off. I found that taking the antennas off eliminates the interference. Any help would be greatly appreciated
