Count me as another vote with Eric and Morzh... clean the switch. You are getting one station, even if weak.. that's good news. Clean the switch. You can go to a hobby store and buy an "eraser pencil"... it is like a regular pencil, but instead of lead, it is full of eraser material. You sharpen it like a pencil, then use it on the switch contacts. It will shine them up like new. And you'll be in business.
