Now I got your heart beating.An interesting story on radio noise.The dealership sold a new car probably in the late 50s.The owner brought it back with an occasional POP in the radio.We checked all the usual stuff and found nothing.Being about 30 miles from the delco radio plant in Kokomo In. we took it over there. They concluded static electricity was build ing up on the curb feelers the owner had installed.Took them off and the pop was gone.By the way I bought several CB radios from this plant that they decided not to market.Probably made by some one else but had a big GM on the face.
