Does anyone know if the S20R had to have jumpers on the acc jack on the
back.

Yes. The octal socket on the back is designed to allow the radio to be
operated from a vibrator power pack, and for AC operation a plug with
one or possibly two jumpers is required. Unfortunately I don't have the
information on which pins need to be jumped handy -- I'm sure someone
will come up with that information.
