As someone else already posted, Zone 1, channel 1, is the repeater enable/disable command. If the controller is set for default operation, the command 100110 will turn this channel off, and it won't repeat until you turn it back on with the command 100111. That's about the only command you really need to memorize.
If you set the receiver to require PL or DPL, that will keep most of the foolish users off when you're not able to listen. In practice, you'll get very tired of turning the repeater on and off. Get more people interested in it and they too can be control operators. Eventually you'll just leave it on all the time (like 99.999% of all the other repeaters in the world). I have three of these controllers, and two are running with MaxTrac/Radius radios, all via the front panel RJ45 MIC jack. I added a COR circuit (one transistor, one resistor) inside the receive radios which comes out on pin 1 of the MIC jack; that simplifies the wiring considerably as you don't need the accessory jack at all. The wiring is very straight forward. Remember that the GM300, like all of Motorola's mobile radios, is not meant to operate continuously as a repeater transmitter, so don't run it at full output power and definitely add a high volume fan blowing on the heatsink.
