That's interesting. I hadn't thought of the overlapping comms issue. I took a class in Salina some time back and we were testing the system. I was using an MBITR on 39.700 and we patched it to 800. The system sounded great but the fact that there are no low band repeaters and the 800 was nearby might have prevented the issue you mentioned.
I do notice you can key up several of the Uhf interop repeaters with a hand held all at the same time. They end up sounding like 10 Meter ham during a band opening.

When you use any of the call channels to contact the KHP Central Dispatch- it keys up every call transmitter in range. What you end up with is complete jibberish. The only way I have successfully arranged for a Motobridge patch was via cell phone- and even then the process was painful.
The audio quality you get even when the patch is up (the exception is on 800) is poor. I was within a mile of one of their tower sites and could not get a clear signal to them on any mutual aid channel due to the overlapping repeater signals.
I would not rely on this system as your Mutual Aid comms answer.
