Is Phoenix AZ PD Encrypted Now?

[zerg901]

The database only shows 2 encrypted talkgroups for Phoenix PD. (2 tac channels at the airport). Posts in the forums seem to indicate that tac & detective & car/car talkgroups are encrypted. Can someone clarify? Peter Sz

I believe the color coded chart is a better example of what is and is not encrypted. Basically anything white on the chart isn't encrypted. Plenty of talkgroups to monitor in the clear.

Scanner Frequencies: Regional Wireless Cooperative (RWC) Trunking System, Phoenix, Arizona

Take a look at the Mode column of talkgroups. Anything with a "D" you will be able to monitor. This included all the standard Phoenix dispatch talkgroups and HOT dispatch talkgroups.

Anything with an "E" in the Mode column is encrypted and cannot be monitored.

There are also a lot of talk groups not posted in the database because they are encrypted and a)can't be ID'd b)would be kind of pointless to post since you can't monitor them anyway.

The chart doesnt seem to match the listed talkgroups very well.

Apparently the bottom line is - dispatch channels and hot channels are not encrypted. (IIRC, Phoenix PD assigns a "hot channel" for any crime in progress.)

Questions -

Is G15 the same as OS?

Is G13 the same as OS1?

What is Air Ops? - talkgroup? conventional?

PPS1 thru PPS6 - what is that?

SPTAC 1 thru 4 - what is that?

MUNZPD - ???

ITac vs INTER vs IMS - ???

PD TECH - ?

Fire West & Fire East - ? link to fire dispatcher?

Thanks for your help - Peter Sz

Ok, I have a question for those who listen to the RWC TRS.

Shall I delete the old mapping grid that was initially pushed out when the system first came on line? I hesitated deleting it as a reference, but this is not the first time that someone has pointed out that they don't match. The system has of course migrate to other areas.

Thoughts?

Hi Peter,

To answer some of your questions, the chart that is listed on the RWC page is very old and should be used as a loose reference. Many of the channels have changed. Also, “G” and “H” deck channels seem to be inconsistently programmed in different agency radios. Long story short, there is not any solid information on a lot of the rarely used channels. We all learn by listening.

Is G15 the same as OS?
-unconfirmed. DB lists G15 as “Event Security 2843”, SWFD lists as “Air Operations 2883”

Is G13 the same as OS1?
-unconfirmed. DB lists G13 as “Event Security 2844”. I have also monitored G13 as 2844 during Fiesta Bowl monitoring. SWFD lists G13 as “OS 3 2885”

What is Air Ops? - talkgroup? conventional?
-There are several Sky Harbour Air Ops talkgroups:
1182
1199
1188
Again, the usage descriptions of these talkgroups vary depending on sources.

PPS1 thru PPS6 - what is that?
-These are mutual aid or interoperability channels. Unconfirmed as:
G1 PPS1 2904
G2 PPS2 2903
G3 PPS3 2902
G4 PPS4 2900
G5 PPS5 2899
G6 PPS6 2898

SPTAC 1 thru 4 - what is that?
-These are also mutual aid or interoperability channels. Unconfirmed as:
G7 SPTAC1 2897
G8 SPTAC2 2896
G9 SPTAC3 2895
G10 SPTAC4 2888

MUNZPD - ???
-I think you are referring to MUN2PPD 2901. This is a mutual aid talkgroup for city services to be able to contact PD. Unconfirmed.

ITac vs INTER vs IMS - ???
-ITac are simplex and repeated frequencies that are used nationwide for interop. Channel names do not match exactly to the link below, but here are the frequencies.
Common Public Safety - The RadioReference Wiki
-INTER are interoperability talkgroups. All are unknown or unconfirmed.
-IMS are Airport “Incident Management” talkgroups. All are unknown or unconfirmed.

PD TECH - ?
F13 Radio Technicians 2908. Unconfirmed

Fire West & Fire East - ? link to fire dispatcher?
These are encrypted and no way to monitor. Most likely Mutual aid talkgroups between PD and Fire

All of the talkgroups that you are asking about are very rarely used and there is not a lot of solid information. Phoenix has been using this radio system for 4+ years and there is still very unreliable information about talkgroups other than A, B, and C Decks. Tempe and Peoria who have only had their new systems online for just a few months, and their channels are almost fully mapped! I would like to see some more accurate information for Phoenix.

Fire is now starting to use “K” and “L” deck talkgroups that are also unconfirmed. If anyone has any solid information about D to L deck talkgoups, please submit to the database for updating.

I don't think you should delete it..it's still a great reference to look at. I got a look at an updated version of the grid a couple weeks ago and it wasn't that much different at all. A few channels were different and some of the encryption was different, but overall it was very similar.

Thank you,

Too bad it wasn't possible to obtain a copy to update our version

Yeah I saw it hanging up at PPD communications.. maybe somebody could contact the department and see if an updated version is available. Seeing that most of the PPD stuff in the SWFD books are provided by the department, it doesn't seem impossible.

Apparently it would be correct to say that the Dispatch / Primary talkgroups, and the Chase / 'in progress incident' talkgroups are not encrypted - but the car to car, detective, SWAT, info channels are encrypted.

Some of the interop channels are encrypted - some are not - or some have not been IDed yet?

How about conventional mutual aid channels? 851.0125 - 851.5125 - 866.0125 - 866.5125 - 770 Mhz ??? Any use heard there?

Just wondering. Peter sz

PS - there seems to be approximately 20 "sites" listed for the system - but some are "simulcast". Maybe there are 30 to 40 repeater sites overall?
