Catholic University Using Capacity Plus System?

As a follow-up to a previous post, I'm getting more confident that Catholic University is using 462.1000 and 463.5500 as a MOTOTRBO Capacity Plus system. The signal strengths of the two frequencies are the same, and also seem to be about equal to the signal strength of 464.5750, which Catholic is using as a conventional TRBO repeater. Also, 462.1000 and 463.5500 were both licensed recently, and the chances that two recently-licensed frequencies are for different systems seem nil. Finally, the Capacity Plus data burst is present on both of these frequencies, but at different times. (It will be on 462.1000 for a few minutes, then switch to 463.5500.) That seems to be a strong indication that the frequencies are part of the same system. I'm guessing that the Capacity Plus system is used for engineering/housekeeping. If my theory about Catholic using a TRBO conventional system and a TRBO Capacity Plus system is correct, it's interesting that the University didn't simply build a three-channel Capacity Plus system.
