Talking Pinal TRS Coming Alive :)

Well, well, well, looks like we will have some work for the Pinal County listeners. On the way home yesterday from the Phoenix area I picked up the Pinal County TRS with two transmitter sites active - Sacaton Peak, and one I called Red Rock. The license says 19 miles SE of Eloy, and I plotted it just west of Red Rock on the other side of I-10.

Neither is transmitting anything but the primary and secondary control data and the channel data frequencies, which are in line with the FCC license WQYN844.

No Neighbor sites are being referenced, indicating, this is a very young stage in this development.

Two more sites will become active, one near Stanfield and one near Queen Creek.
Stanfield - 851.5875mhz, 852.925mhz, and 853.7125mhz
Queen Creek - 851.375mhz, 853.125mhz, and 853.70mhz

Let us know when you see those two sites active and of course, any other new activity.

Pinal County P25 System Trunking System, , Arizona - Scanner Frequencies

Thanks,

Here is my take on this, with no real proof, other than under the documents submitted when this county, and Maricopa County submitted bids. "AZWIN" was referred to in the documents without further clarification. I too believe that there will be a link into AZWIN.

But probably only for a small number of TG's, and only for cross agency communications. This was referenced earlier by others about four TG's, one for LE, Fire, Public Works, and a catch-all.

Time will tell

Yeah agreed but now with the political outlook changed, pinal and Maricopa S.o. may not play nice anymore.

I am receiving Sacaton site and there have been keyups on talkgroups 10001-10016 that sound like testing. The talkgroups I heard were P25 Phase 2 in the clear with "Radio Service" testing. The Sacaton site is showing no neighbors at this time.

In addition to Stanfield, and Queen Creek that FLANO listed, there is another callsign associated with the system:

WQYJ635 (PINAL COUNTY) FCC Callsign Details

Listen for activity and control channels on these sites too:

Florence
851.0625
851.4500
856.9625

Casa Grande
851.2000
851.3500
853.8625

Kelvin
851.6500
851.8000
856.9875

Mammoth
851.1750
852.2125
853.0375

Mt. Lemmon
851.4000
853.0625
853.9500

Globe
851.9875
852.8625
853.7500

Excellent Joe ! That makes ten sites and fits in with what is known so far for site numbers.

I notice that some of these frequencies are shared with Maricopa's legacy system. Why aren't they 700MHz?

I'm not sure anyone has an solid information on why they are using 800mhz (other than those on the inside). It could be licensing related? This is why the State is using 700mhz and not 400mhz or 800mhz for AzWins. It could be preference of the system admins? This is why the RWC moved everything from 800mhz to 700mhz. The City of Phoenix was struggling with interference on 800mhz from other systems like Nextel.

It might be the same reasons newer systems like Pima County, Marana, ASU, and Gila River are also using 800mhz if anyone has any information on why these systems chose 800mhz as opposed to 700mhz.

Could be cost and geographically of the area.
Rws is not as wide spread as pinal system is, Marianna is a older system, alas asu and gila.

From what I understand, as long as the licenses are re-banded from 866-868Mhz to the newly allocated 851-85(?)Mhz public safety block then its fine. Nextel/Sprint is grabbing the upper block.

I identified two more sites up ... Mt Lemmon and Stanfield.

Curiously, I receive excellent coverage for Mt Lemmon on I-10, just outside to the south of Phoenix. Once I hit Marana in Pima County, I basically lost the Mt Lemmon signal. Anything south of the range is extremely weak to poor signal quality

Stanfield is hearable south of Phoenix along I-10, to just south of Marana in Pima County.

The Sacaton site is showing a neighbor site 104 with control channel 853.0375. This should be the Mammoth Site. If anyone is in that area, see if you can hear it.

Sacaton is also showing a neighbor site 169 with control channel 853.96875. This is not a licensed frequency for this system, and the site number is odd. This might be a test freq/site.
