Welcome to iRV2!
You have come to one of the friendliest forums around...but you may not be getting as good a response as normal because you are vague on the radio description. You should post which brand/model it is.
If it is the Magnadyne...then RV Roamer may have hit it on the head...that is usually the ONLY problem that this <STRIKE>POS</STRIKE> radio has not had.
Good luck figuring out your problem...and again...Welcome to iRV2!!
PS.. Would you like some "Winnebago Karma" to go along with your "pogo1957" name?
