I suspect no one has responded because people are not sure and don't want to lead you down the wrong path, Mark.
You need to make the circuit closures at your key that the M1 through M4 buttons do on the front panel. To do that with simple switches would involve paralleling those button contacts with connections to the switches at your key. First you'd have to dig into the front panel to make the connections and then there's a whole spectrum of problems that might occur with wires connected to those circuits. Noise radiation into the receiver, RF pickup that would activate those functions spontaneously, or activate some other Front Panel board unexpectedly when you transmit are just a few that come to mind. Bottom line, it appears to require some serious technical evaluation and testing of the installation. The better approach would be to command those functions via the rear panel RS232 interface, but that requires a lot more than a switch at your key. It might be done with a "black box" interface unit to produce the right data outputs in response to a switch closure at your key, but again that also requires a significant design effort.
