We can beat this topic to death, the MTR will do just about anything, MANY different setups, multiple channels, remote control channel change, etc. etc. etc....If the MTR units have a duplexer, and being used as a repeater, highly unlikely that they are multiple channels.
I suggest: Have a tech with MTR software (experienced with the MTR), look at the system and determine how they are setup and what frequencies are in them. Then you will know what channels are where, and if there is still a third channel out there, have a good old fashioned fox hunt.

Over the last few weeks, we have been trying to determine the location of our repeater. The place were it is listed on the FCC license paperwork does not exist. I know, I am pushing them to get it updated. But that is another story all together. I do have access to a "radio house" located at our high school football field and it has two MTR2000 in it, plus two different antennas. One connected to one radio and one connected to the other. One radio is marked with the description of KISD PD, which is our police department for the district and has the following frequency pair listed on it: VHF: RX 173.325 DPL 331 and TX 158.385 DPL 331 The other radio is marked the following: UHF: 451.725 / 456.725 There is no documentation with this equipment, the person incharge of them originally left the district some years ago and no one knows anything about them, expect where they are located, as far as these two boxes go and what frequencies that have listed. Which brings me back to our department, we can find out repeater located anywhere physcially. Our repeater pair is listed as: UHF: 451.750 / 456.750 That is according to FCC, repeater listing and other information I have been able to obtain and by listening to it on a UHF amateur radio to see which frequency they were on. That being said, it is possible that the MTR2000 that is marked with the one UHF frequency, might actually have both pairs programmed into it, but only one can run at a time, right? Is there a way to find out if there is more than one frequency is programmed into the unit and if so, how might we go about that? Another reason I am asking is that we might be upgrading our system in the very near future and I might be able to get my hands on these repeaters.

This could be for either amateur operation or commercial operation, but it relates to the repeater itself. Can a Motorola MTR2000 setup on UHF be setup to function as a repeater on more than one pair of frequencies? I know looking at the brochure on the website, it says that the NO. of Frequencies are upto 32. Does that mean it can handle two different sets of repeater pairs at the same time in the same radio? These are commercial frequencies I am listed at commercial, but they are for example purposes: Can the following setup work with the MTR2000? Frequency Pair 1: 451.725/456.725 Frequency Pair 2: 451.750/456.750 Can one MTR2000 handle both of these at the same time?
