Future of OKC radio

[toad99]

There is so much crazy stuff I hear on the dispatch channels that I won't miss the Tac channels. Heard one discussion this morning about a guy that said "I am a warrior and intend to die in battle with the police". Plus all the people that are not taking their "meds", there is plenty to hear on the dispatch talkgroups. Hope they leave the FD Tac talkgroups alone.

Radio programming/swaps appear to be continuing. Based on the last few weeks of data, there have been 1442 radios utilize the PD talkgroups, and just judging by radios they affiliate with the new system, they are nearly half-way finished. Last count, I have 686 radios that have affiliated with those same groups. It does not appear many fire radios are setup yet (patches aren't active either). There has been some activity on the "private calls" similar to the old system for station alerting. I wouldn't say it's setup fully yet.

If you have two radios (one capable of PV, and one P25), its interesting to listen to one talkgroup...you can hear which systems the units come in on based on the audio delay.

It appears all PD Tac channels are now encrypted. Looks like we won't be able to listen to funeral processions anymore.

I have yet to see the actual TAC channels 1-9 on the new system yet. Right now it appears whatever is encrypted on EDACS is encrypted on P25 II. Have you seen any TGID's show up encrypted on the new system that wasnt on the old?

Just a few of the PD TAC channels, namely TAC 3 and TAC 4. There look to have been a few "non enc" transmissions on them. Maybe those are linked from the old system?



It also appears all the channels are utilizing the same encryption key. Not that I'm saying this should be decoded, but it would seem with this fancy radio system, there would be multiple keys in use! AES algorithm.

What are you using to monitor the system? Those screen grabs dont looks familiar. I use dsd fast lane and unitrunker

Same...and then some fun analytics with excel/powerbi on top of the data logs.

Another change from the old system...PD Training 1 is encrypted on new system (except for the console), where it wasn't encrypted on the old system. PD Training 2 continues the setting from the old system.

Only thing different I see so far today is an encrypted TG of 430 thats not listed in the DB.

 

[GeoFenceFound]

Add TG 568 thats encrypted but not listed in the DB.

 

[mam1081]

Add TG 568 thats encrypted but not listed in the DB.

...and neither 430 nor 568 seem to have links to the EDACS system. I noticed some testing on EDACS (in clear provoice) the other day on a different talkgroup...in the 900 range (one I didn't have tagged).

Now that apparently the system is "online" and live, anyone want to list on here how are various scanners working with the simulcast in different areas of town?

I have 1520 total radios that have used the PD talkgroups in the last few weeks - and 1200 radios have affiliated, so it appears they are continuing to add radios to the system.

Still not much fire...52 radios have used the fire talkgroups, 79 have affiliated on those groups.

I have downloaded the latest data and made a favorites list for the new OKC system on my 536. Most of the audio on the new system is pretty muffled, compared to the ProVoice favorites group I have. Are there any settings that I might need to change to help this audio not be so muffled?

Unfortunately some scanners do better than others. I personally have a 536 and 436 and it sounds bad no matter what trunked system I listen to. I have better luck with other means i.e SDR.
there are some settings in my 536 that made it noticeably better but im not home at the moment and its been a while so I cant remember what settings. Also I dont know what is officially on the new system or not. Also as everyone moves to the new system the techs will likely adjust things so expect it to change. How does the fire alert TG sound on it?

I agree that even ProVoice isn't perfect on my 436 and 536, but it sounds tons better than any of this new traffic. I have not tried it yet on my 436, just the 536. The fire alert TG sounds pretty bad too.

If you get a chance to share those settings that made improvements, I would much appreciate it!

are you close enough to reach the norman system? If you can try that too and see what results you get.

I will try that here in a while. Probably cannot reach it as I am on far NW side of OKC.

I have gotten some LightHorse P25 in past and it sounds great.

It does not appear I can pull in Norman from here.

I am in far NW OKC and listen to both the Provoice and P25 OKC systems on a 436, 536, SDS100, SDS200, and a 996P2. The new and old system audio is all over the place in quality. The audio is still overloaded a lot of the time (usually the dispatcher), and the fire alerts are some of the weirdest sounds I've ever heard. I think a lot of the audio issues for OKC are the consoles and poor microphone usage on both ends (the mobile units can sound like they are talking into a pillow). I can pick up the Guthrie site of OKWIN and the P25 sounds vastly better than their OKC site, which suffers from horrible multipath distortion in my area, and the Guthrie site has all of the Logan County stuff, OHP comms, and statewide stuff, just not Edmond. I have not found any settings on any scanner that will improve the OKC audio.

Just to clarify are you asking about the Norman P25 type 2 system or the OKWIN P25 site 41 in Norman? Thanks

I have logged 1,974 radios that have used PD talkgroups in the last few weeks - and 1,693 radios have affiliated on those groups. Looks like almost 500 more radios programmed this week. Still not much additional logs on the FD radios.

Funny if you look at affiliation by day, Sat and Sun are always low...are the radio shop guys doing that much affiliating? It also looks like no additional work occurs on Monday (same numbers roughly as Friday - except for March 23):
