[arm-allstar] Pulse-Back & Building a Repeater

I don't have an MSF5000 in front of me so I can't tell you exactly what 
pins these signals are on, but you need to run a wire jumper from RDSTAT 
to TX PL STRIP inside the station controller and this will cause the 
5000 to encode PL only when the receiver signal is valid.  (COR + valid PL).

It's a really easy modification on that station.
