As far as I know the early Maxtrac did not implement "Channel Steering" (Motos' name for binary channel selection). You needed to use a late Maxtrac (more precisely one with the late logic board), a Radius LRA series or a GM300 to get that feature, and then you had to do some very careful programming of the radio to get 4 bits of channel steering, a RUS pin, and a transmit PL encoder on/off pin.
Be careful what you program into your remote base even if you are the only one at a site. I found out the hard way that 147.51 takes out a repeater with a 442.525 input (do the math). If you have a busy site it gets even worse. Radios with plastic cases (i.e. leaky synthesizers) have gotten a few friends in hot water with various site managers. Remember that something that passes spec for type acceptance can still leak enough to be heard in an adjacent rack.
