I have a 1994 Ford Ranger truck. I just installed a brand new cb and antenna. I have the power hooked stright to the battery and the ground to the ground on the battery. I can receive perfect, I can transmit perfect with car only idling. When I drive and try to talk, all that others can hear is a high pitched squeal. I tried a friends cb in my car with the same results. I have installed cb's in the past and not come accross this situation. Any help would be greatly appreciated.
