Folks, could use a little help please. Comcast installed their VOIP phone sytem in my home the other day and they had to cut the SBC wires outside my home in order to get the system to work. Ever since they did that, my reception on AM radio thru my receiver has been hijacked by some religious station on all channels. I have tried moving the AM antenna around, no help. Do I need to ground the receiver and if so how do I do that? Any help would be appreciated.
