Maricopa County Community College District

[Kars10az]

It's sounding to me like it's an EAST/WEST gig, and not a school-specific thing as far as the TGs are concerned, but I haven't sorted it all out yet. The unit numbers seem to be school specific, but not the channels. I've been listening and building a spreadsheet, but I haven't had the time to just sit here and listen. I'm listening from Tempe

I've heard the following TGs

TG 4552 off North Mtn
TG 4554 off North Mtn, South Mtn and White Tank
TG 4555 off South Mtn, Thompson Peak, F and B
TG 4557 off South Mtn, Thompson Peak, F and B

4555 and 4557 seem to be East or South Valley and 4552 and 4554 seem to be West or North Valley. I haven't heard anything that I can say for sure is a specific school, but I'm not all that familiar with the schools.

I was able to listen a little more tonight. Here is a summary of what I can confirm, what I suspect, and what is unknown:

-Glendale = 4552 (4xx Units)
-South Mountain = 4554 (7xx Units)
-Gateway = 4555 (3xx Units)
-Scottsdale = 4555 (11xx Units)
-Chandler-Gilbert = 4557 (1xx Units)
-Mesa = 4557 (5xx Units)

Suspected:
-Estrella Mountain = 4552? (2xx Units?)
-Paradise Valley = 4554? (6xx Units?)

Unknown:
-Phoenix (2 campuses "Main Campus" & "Osborn Site") = ?
-Rio Salado (15 Buildings throughout the Valley) = ?

From what I can see from this thread and the RR DB, it looks like the first 6 are confirmed and in alphabetical order:

100 Chandler
200 Estrella
300 Gateway
400 Glendale
500 Mesa
600 Paradise Valley

The rest either don't follow suit or are possibly wrong.
700 shows up as South Mountain but I would think 700 would be Phoenix and 800 Rio Salada, and South Mountain would be 1000.

Scottsdale is apparently 1100, but should fit into the 900 slot.

OK, done rambling, back to listening. Maybe I can track down or confirm some of this.

The DB has all of the talkgroups and colleges that are currently using the RWC identified. Please also note that I am seeing patches between talkgroups at times, so this will throw you off if you are using a Uniden scanner as they do not follow patches on the RWC.

Currently 4555 is patched with 4557 so Uniden scanners will hear all schools assigned to both 4555 and 4557 only on 4557. Please note that talkgroup patches change on a regular basis.

I am hearing a new call signs "800 Base", 8xx units on 4557/4555 patched talkgroups. 8xx units are dispatched by "800 Base". I haven't identified a campus yet. All I caught was "North parking lot patrol".

I am also hearing a new call sign "900" that is dispatching for multiple campuses. There are two dispatchers for "900" with what look like console Radio IDs 705001 & 705002.

From recordings on 6-25:
At 8:00pm "Gateway" called "900" stating that they were 10-7. "900" broadcast that all 300 units should now report to "900" and stated they were taking over radio and phones.

At 11:00pm "500 Base" broadcast that 900 would be taking over all radio and phones.

Around midnight "1100 Base" broadcast that 900 would be taking over all radio and phones.

After midnight 4552/4554/4555/4557 were all patched talkgroups and all units were dispatched by 900. I think it is a safe assumption that "900" is their new consolidated dispatch center.

I just caught talkgroup 4556 Encrypted on Thompson peak with MCCC Console ID 705002 and another 705xxxx radio ID. It looks like they have some encrypted talkgroups.

I'm guessing that 4553 is also Encrypted, but I cannot confirm as I have never caught that one.
