Future of OKC radio

[JStemann]

Just looking around, trying to figure out what OKC has planned. I know the EDACS system is at or near end of life, but I haven't seen anything on here about what's next. I ran across a RFP from over a year ago for a P25 Phase 2 system from OKC government, but haven't been able to find any further details.

Has anyone else seen/heard anything on their plans?

Jeff.

Don’t know their intentions but there’s the new OMACS system starting up.

Oklahoma City P25 Upgrade

Just looking around, trying to figure out what OKC has planned. I know the EDACS system is at or near end of life, but I haven't seen anything on here about what's next.

YES, there has been significant activity in regards to that original RFP.

On Mar 28, 2017 the OKC City Council passed (9-0) a "Joint System Purchase Agreement with Harris Corporation, P25 Phase II 800 MHz Trunked Simulcast Radio System and Microwave Network, not to exceed $13,114,808.20."

Upon clicking on this simple line item in the City Council minutes there are over 12 exhibits of the contract with Harris that includes: a full system overview, interoperability using the VIDA Core, full color coverage maps, site selection, microwave network, and an equipment list describing a "Thirteen (13) site 20-Channel P25 Simulcast System."

The schedule in exhibit 4 indicates the total overall project should take 598 days but that includes the decommissioning of the legacy system. The project should be wrapping up the "Customer Design Review" and starting the manufacturing process. Actual "User Migration" should be about two years away.

This detailed info and the color maps can be found at the following City of Oklahoma City website:
https://agenda.okc.gov/sirepub/mtgviewer.aspx?meetid=4155&doctype=MINUTES

Look for agenda item OCMFA C-2 and click on the link for the supporting documents.

Also: TUSA Consulting in Louisiana had their contract extended into 2018 for implementing and monitoring the city's P25 upgrade. (from the 12/5/2017 minutes)

I haven't had my 536hp very long so I am wondering will it receive this new system? Will the new system still use provoice?
Thanks..

The new system will be P25 phase 2. Your scanner will receive it but may have simulcast distortion problems and not receive it well depending on your location.

Will the new system still use provoice?

No. Only EDACS systems have ProVoice.

I receive Okc good now in Edmond so hopefully I can get the new one as well.

lets hope they do not encrypt.

I also didnt see portable radios listed on the equipment list. I wonder if they will be keeping their existing radios.

Several FCC license modifications filed yesterday.

It looks like they added 20 new frequencies.
P25 control channels will probably show up on these first but I could be wrong. They could resuse some of the existing EDACS frequencies first.
851.1875
851.9875
852.4750
853.2000
853.6000
853.8625
851.1000
851.8625
852.2625
852.5625
852.9000
853.3000
851.3875
851.7375
852.0375

Going to make a WAG and say that they will stand up the new system on these pairs first, migrate everyone to the new system, then either abandon the old pairs or integrate them into the new system.

Guess we need to start listening to them.

That's what they did here in 2016. Wichita Falls had a 5 channel EDACS PV simulcast system. They got 3 new channels licensed about a week after the new P25 control channel went on the air. After several months they gradually moved 2 channels from the EDACS to the P25 system then finally shut down the EDACS system leaving the remaining 3 channels dead for about a year now. I thought maybe they would add them but so far they haven't, unless they are reserved for telephone interconnect or some other use or reason.

Some other things to bee on the lookout for:
Here they use the existing EDACS decimal talkgroups with extra numbers added to the beginning. 3 digit TGIDs got a 10 and 4 digit TGIDs got a 1.
For example EDACS 791 became P25 10791 and EDACS 1041 became P25 11041. They were patched between both systems for several months.

The first radio IDs used for system acceptance testing were 99800xx range.
The first talkgroups were 6400x, 6405x, 6410x, 6415x ranges (only a few TGIDs in each range).
After a few months I never saw those RIDs or TGIDs again.

I don't remember who the vendor is in OKC. This might be the standard Harris way of doing things. There have been other posts of similar things in other states including a county document with Harris documentation that listed the RIDs and TGIDs for acceptance testing.

I found this in the city council link posted earler. Looks like the same thing I saw for another system in KS.
Go to

and click on

Then find Talk Group ID and Radio Lid in the document.

Glad things are moving along. I just hope we can get these added to our APX 7000's at work.

 

[peterjmag]

This is all good news. Like it's been stated I hope they don't get crazy with the encryption. Seems to be the norm for many nowadays.

 

[plaws]

A little surprised, given our propensity for let's call them "wind storms", that they chose microwave over fiber. ¯\_(ツ)_/¯

........

Apparently the new P25 system will re-use 11 frequencies from the EDACS system

Also the schedule seems a bit confusing to me as far as months/year goes. They have it listed as quarters. Does anyone know where at on the schedule were currently in, or should be in assuming there were no delays?

 

[GeoFenceFound]

This system appears to be somewhat active and is currently being tested. I am hearing bits and parts of a male voice. I have all the data recorded and will take a look at it later today and report back. If anyone has this system in their scanner might want to start listening.

 

[GeoFenceFound]

TGID 324
UID 500951
UID 500941
UID 9989120

A lot of test counts, I’m only searching tgid’s so not sure what cc they were using.

 

[GeoFenceFound]

Add TGID 327, 328 captured today.

 

[GeoFenceFound]

Testing emergency alert tones on TG 530 today.
