OKWIN encrypted Talkgroups

[bbpowers92]

I've been hearing some talkgroups "2018,2019,2021" lately with radio ID's 9611, 95135, 8054, 95083. Was curious if anyone had an idea who it might be. These have been heard on Weatherford tower, Elk city tower, Geary tower and OKC tower.

I don't know if you already did this but sort the db page by talkgroup and see where they fit in the numbering gaps. Then see if they are in the wiki. Oklahoma Wireless Information Network (OKWIN) - Unconfirmed or Unidentified Talkgroups by Site - The RadioReference Wiki

Yep, did all that before posting and didn't find anything in the DB.

I don't show any hits on those Talkgroups on the OKC site, but the radio ID's are all EMSA radios.

Interesting, did a little further digging and two of the talkgroups comes back to, MWC Mutual Aid-1 TG: 2019, and TG: 2021 comes back to MWC EM-1.

Just heard TG 885 with ID of 8061 off the Elk City site, encrypted so I couldn't tell who it was.

That ID comes back to an emsa radio. Not sure why that ID would be on an elk city site and encrypted unless they changed the way they do their long distance transfers and how they communicate.

All of a sudden since before the first of April I am not picking anything up on the Elk City or Weatherford tower. I keep getting error messages about unrecognized OSP OPCODE. @bbpowers92 are you seeing the same?

 

[bbpowers92]

@kawilliams, nope, hearing everything fine on my end.

They sounded just fine to me yesterday.

I have discovered some weird USB issues. If I unplug all but 1 dongle the frequency is spot on. But when I have more than one plugged in the two trying to tune to the p25 system can’t get a lock on the signal and is off enough it can’t correct it. This is something that started around the first of April. Up until then I had 7 RTL-SDRs working no issues. Now the two I am using for the OKWIN P25 system are having issues.

I have used several brands of SDR dongles. Some have short life spans. Replace that one and see if it works. You should be able to adjust each dongle too for frequency correction.

They are all RTL-SDR v3s. However I can’t narrow it down to one because they all work when plugged in one at a time. I’ve tried different hubs, computers, even different OSs. So I think it something with the SDRs and since they were all purchased at the same time they’ve all got an issue.
