7.7 has been showing as a neighbor now for a while, so I would guess it is online. I cannot pick it up from my house or in Tulsa.

Here is the current neighbor list from 10.10 right now.

7.7 CC is reporting 856.3375
49.49 is reporting 855.6875

 

[wx5uif]

Sand springs is also now reporting a neighbor of 27.27.

27.27 is likely Nowata, but could be Hinton. Any other AEP sites with 855.7625 are too far away to be neighbors of Sand Springs.

The AEP/PSO EDACS systems in my area are used for SCADA in addition to voice traffic.
I saw a lot of data iCalls on Unitrunker.
When the Frederick and Comanche OK sites switched to P25 I noticed no iCall or data activity on the P25 control channels.
Instead each site now has two additional channels with some kind of steady data stream.

For example Comanche:
855.3125 P25 cc
855.5125 P25 cc
855.8875 ?
856.4125 P25 cc
856.9375 data
857.3625 ?
858.3625 data
858.9125 ?

and Frederick:
855.2625 P25 cc
855.6125 ?
855.7625 P25 cc
855.9375 ?
857.2875 ?
857.8875 P25 cc
858.3125 ?
858.8875 ?
859.2875 data
860.3375 ?
860.3625 ?
860.8125 data
860.9125 ?

I have not logged any activity so far on those sites so I don't know how many voice channels they really have and I don't know if the frequencies marked ? are used for anything.
DSD+ and Unitrunker don't recognize the data format. It sounds almost like OpenSky. That must be what the new 18 & 19 kHz emission designators are for. Are you guys seeing anything like this in the OH area?

Yes, I see similar. No actual data burst anymore, but instead "data" showing up on P25 channels. I hear ya about OpenSky -- if I look at the spectrum that was all used by local EDACS sites in the past, there are many 24/7 signals that are something else which is undetectable by DSDPlus or Unitrunker. Im sure it's the same signals you are referring to that sound like OpenSky. Clearly wideband signals (as compared to a C4FM or PSK signal). It's very intriguing.

If you run DSDPlus (Fast Lane at least), in my area, on any of the sites, there will be some red messages (I forget the message -- something basically indicating an unknown opcode or something else). I can't grab a screenshot because all my stuff is packed up for the "big move" to our new house.

if you run UT or DSDPlus for the purpose of doing full trunking (monitoring CC / playing voice calls), you will likely also notice that the radio IDs shown on the CC will be completely different than the radio IDs shown when tuned to a voice channel. And, in my area, all of the unit numbers and over the air numbering have changed. A lineman truck that used to be "7514" for instance is now something new. And it's the last four digits of the radio ID shown on the voice channel.

Looks like I need to update those sites in the DB. Are the " ? " frequencies also shown in UT, / DSDPlus or are you just noting them from the license as " ? " ?

It sucks that I can't receive Lawton all the time. The two sites I can receive most of the time are in counties that are served by Cotton Electric Coop and SW Rural Electric Assn. and never had much traffic.

 

[nd5y]

No. The ? are unknown. They are licensed but not used (yet) that I can tell. They might be voice channels but I haven't seen any use yet.

 

[nd5y]

I don't think these data channels are part of the trunked system, they just share the same license.

I'm in a rural area, and the AEP sites around me are rarely busy unless there is a major storm coming through. So I really don't get a chance for much "quality" monitoring of AEP.

Ok, that is what I figured. Thanks, Tom.

Lawton was full quieting this morning. I ran Unitrunker for over an hour and got several TGID & RID...
All the talkgroups with one hit were from one radio that appeared to be flipping through channels.



Also I could not find any data channels like the other two sites near me have.

 

[nd5y]

Lawton, OK has a new neighbor that came on line sometime this afternoon.
31-31 855.0125
Probably Clinton (or Weatherford if the site wasn't moved yet. See the pending app.)

I updated the wiki and my map (both reflecting Clinton as 31.31). Nice catch. They seem to be going full steam in OK.

Thanks, Tom

Any word on KY yet?

Any word on KY yet?

I haven't heard anything about any active sites in KY yet. Of course, that doesn't mean none exist. I'm dying to see if they are part of your I-M System ID or not, as I think we both suspect they will be.

@Remington12G is one of the guys who I think will be watching out for KY sites, either him or his brother. Between them I think they are watching KY and VA to some extent.

Since they started using the system in SW OK I have logged some talkgroups.
We need a wiki article for unidentified talkgroups.
Should I make a new unidentified talkgroups article for the whole system or should we put them in their own section on the site research articles?

Edit... just noticed the 1F5 page already has that so I'll do the same for 1F9. It can always be moved later if needed.

Personally, I'd suggest that you just add a section to the existing 1F9 wiki page, specific to unknown talkgroups. Such sections already exist on one or two of the other pages.

- Just edit the UNKNOWN TALKGROUPS ON 1F9 SECTION there and put your findings in between the two "pre" directives.

Frederick OK site 41-41 is showing a new neighbor now.
33-33 858.7875
Probably Mangum
