Pinal County Sheriff on the YRCS, TG 1050?

I'm running a wildcard (GRE PSR-500) on the YRCS right now, and it sounds like PCSO is running a patch on TG 1050 on the YRCS, off of the South Mtn site. I haven't discovered what analog conventional channel they may be patching from.

Has anyone else run across this talkgroup?

I also heard YRCS talkgroup 1050 active this morning. I can receive all of the known Pinal county freqs from my location. The activity on YRCS talkgroup 1050 is not patched to any of the known freqs.

I am also noticing that Unit IDs on talkgroup 1050. There is a unit id for the dispatcher, and different unit IDs for the mobiles. This is not consistent with a patch as all would be on the same unit id. It seems that they may have been testing radios loaned to them by DPS. I just heard this broadcast:

“All units using the DPS channel for testing, please move your traffic to SO-2.”

YRCS talkgroup 1050 is quiet again. When it was active, it seemed like they were using it for info/record checks. This would be consistent with PCSO's use of their Channel 2.

It seems that 10xx talkgroups are DPS. There are several identified in the DB. In addition to what we have documented in the DB, I have also caught radio traffic in the clear on YRCS talkgroup 1096. It DPS motor officers testing radios on what they referred to as channel “7 Admin”. As we know DPS District 7 is motor officers. I think there are a lot more DPS channels out there then we have identified. I’m guessing 1050 is a DPS channel (Possibly a District 6 channel) that was being used by PCSO for testing. There have been rumors of PCSO wanting to go to a P25 trunked system. Maybe they are considering joining the YRCS/DPS system.

I also heard that "Switch to SO-2" transmission.
The transmissions I heard, most of the time, I couldn't hear the mobile unit, and what I did hear, had that "underwater" sounding audio. That's why I thought it was a patch, rather than a direct transmission.
I'll have to run my wildcard more often to try to catch more.

I've also gotten the TG 2002 in recent months. I don't recall what the conversation was.
Lots of encrypted in the 100, 200, 300, 600 and 700 range.
1100 & 1108 were two I have gotten in the past. 1100 had what sounded like surveillance on a subject who had a worker's comp claim the first time, and a contract barricade company employee checking in with the ADOT Phoenix TOC the second time. 1108 had a car-to-car conversation the only time I heard it.

BTW, "SO-2" is a descriptor for one of the Cochise County Sheriff's Office channels. I wonder if it was Cochise County that was testing?

John,

Exactly what I thought John, SO-2 is called that on the Cochise County conventional freq.

I'll have to give a listen and see if there is a correlation maybe to Cochise rather than Pinal ....

It was active again a few hours ago. I only heard the dispatcher giving back a 10-28. When the mobile unit transmitted, there was only a series of regular spaced beeps.
This has to be a patch or multicast of some kind.

I tried to edit my last post, but RR is being difficult.

I'm listening right now, 12:30pm local. It's Cochise County. I heard one call for a funeral escort in Sierra Vista, and another to talk to someone to attempt to locate another subject in Palomas(?). I've heard several other acknowledgements by the dispatcher, with time stamps.

I'm not hearing the officer/deputy side that often. Only in the call for Palomas did I hear the mobile unit. Other times I'm hearing just a series of beeps, if that.

Now there's a structure fire on Chief Rd that 541 has been dispatched to. I heard 541 acknowledge. The dispatcher also mentioned Wilcox Rural Fire was responding, or they were trying to get them to respond.

Fantastic John. I should be heading to Morenci from Tucson tomorrow morning, so I'll be looking for this.

Spent quite a bit of time in Cochise County and the surrounding areas.

CCSO is in fact testing/using TG1050 for their dispatch of their deputies. Not all deputies have the capability yet to use the AZWIN system, as some are still on the legacy analog VHF system. It does appear that they are having their radios (APX7000s) re-programmed for at least the short term ?

The CCSO radio system is undergoing maintenance/upgrades, so we'll see what happens

The only entity being simulcasted is the dispatcher. And it is being simulcasted on SO-1, SO-2, and TG1050.

If the deputy is still on the analog system, it is not being simulcasted on TG1050. The only deputies on TG1050 are the ones with reprogrammed radios.

I only heard them on Heliograph Peak, Texas Canyon, and Mule Mountain sites. They are not hearable on the Tucson area sites

They're on both the North Mtn and South Mtn sites in Phoenix. Maybe Thompson Peak as well?

I assume they're being carried up here for the radio technicians convienence.

Picked up a couple of sporadic hits on the Mt Lemmon Repeater.

I live in Tempe and hear them on Thompson Peak. I'm blind to South Mtn, so I don't expect to hear them there. I do pick up North Mtn, but haven't heard it on that site yet.
