When listening to AM on my 47-1230 chassis I notice there is more static and hum than I think there should be and I also seem to only recieve stations around the middle of the tuning dial the stations on both the high and low ends do not come in. When listening to FM everything seems ok there I get stations all the way through the dial and I dont seem to get much static or hum. The SW bank I havent picked up any stations. Anyone have any ideas on why I am not recieving stations on AM in the high and low portions of the tuning band, or nothing on SW, but FM seems pretty good?
