I'd say 99% of the issues of this type are from a dirty control.   It 
can be removed, it can be opened and cleaned and it can be re-assembled 
and installed into the radio.   I have pictures of the MULTI control 
which I opened, cleaned and put back in the radio.   It is still working 

The pictures are on the Eagle Groups.IO site under files.

You are making the issue much too complex.  It is the control.
