Thank you Don and Dave for your replies.  I tend to agree with you Don that these are two seperate problems, but I don't know.  In answer to your question the XIT button does work as well as all other buttons.  I did forget to mention that the antenna tuner is a KAT2, which is installed.  

My elmer did suggest that if the wire had become broken or possibly came into contact with the side of the travel trailer (ie. metal) it could have experienced RF feedback which would cause it to lock up and if it were strong enough might have fried the menu.  I don't know, nor do I know how to test for this.  I did disconnect the long wire and ground.  Reconnected another wire not in contact with anything and the both problems persisted.

Bill, Check to see if the XIT button works and report back here.  I believe
you may have a bad solder connection on the front panel board.
