I received the encoder and yes it is a pretty easy job to replace it. Just a bunch of screws to pull out for the top, bottom and front covers, fold the face down, pull the front circuit board and the knob and replace. I had read on a few posts that the IC may be the issue, but when I get it back together, I'll know if it was the encoder itself or not. Unfortunately it is a sealed unit so I couldn't clean the old one. Now I'm trying to find a trim pot for the mic gain. The mic gain was bent and wouldn't turn easily. I tried to straighten it a bit and the shaft snapped right off with almost no pressure. That's pot metal for you. Once I find a replacement and solder it onto the board and find a power cable, I can start looking into a power supply and antenna and all the other fun stuff to use it. Thanks for the reply.
