New Talkgroups Found on Charles, Prince William, and Stafford Systems

Hurricane Irene provided a chance to catch a bunch of new talkgroups on the various public safety trunked systems:

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.

Additional Frequency for Marriott Inn & Conference Center, UMUC

The Marriott Inn & Conference Center, University of Maryland University College appears to be using an additional frequency (461.2250 [ d311]) in addition to the two (461.7500 [ d311], 464.2250 [ d311]) previously found. The Marriott is licensed for a total of four frequencies.

Sidwell Friends School Frequency Confirmed

Sidwell Friends School has been confirmed on 461.3875 [100.0]. The frequency is licensed as mobiles-only, but is used as a repeater. It sounded like security was using the frequency.

Fannie Mae LTR Passport System

Fannie Mae's multisite LTR Passport system has been confirmed in use at another site: 3900 Wisconsin Ave. in DC. This brings to four the number of confirmed sites. According to its licenses, Fannie Mae has another site in DC, and one in Urbana, Maryland.
