Yes, I have about come to the conclusion that it is HEI interference due to hooking the radio up at the batter and it works fine. Yes, I am looking for a way to lower this interference. I think it would not take that much shielding of some type to do it but have never really had to do this type of shielding before. I seen some different types on the internet but do not know the best kind to try. I hate not be be able to use this option on the radio.
