Nice! I wondered whether TDMA = phase 2 and FDMA = phase 1. All this time I just assumed I wouldn't be able to pick them up. Appreciate the responses, thanks!

Yes, T Next to the site name means it is a TDMA control channel, just as T in the mode column of the talk groups indicates it is a phase 2 talk group. At this point in time it seems most phase 2 systems have an FDMA control channel, with the rare exception of a few wide area power systems built with L3 Harris hardware such as AEP and Duke energy

Read the waiver attachment.

FCC approved their waiver request and issued their license.

Imagine an outage in an area not covered by the TRS, where you can't predict the outage and location 10 days in advance (which is basically any/all outages).

(7) At least 10 days prior to operating, AEP must notify all co-channel licensees within 113
kilometers (70.21 miles) of those areas in its service territory where use of the waiver
may be required

LOL.

You guys over there a very lucky that AEP are going P25 and building it out whilst still making it monitorable here in South Australia SA Power Network formerly ETSA Utilities migrated from their straight analogue VHF high band system which included crossband UHF high band channels about 7 years ago to the SA-GRN and have 28 allocated fully encrypted talk groups for their communications

That is a shame. Very useful to be able to know what is happening during an outage. at least I think so. There is another multi-state Utilities system here in the states, Duke Energy -- they switched to P25 Phase II (or are still working on it) over the course of the past couple of years, and everything thus far is 100% encrypted.

Definitely very handy to keep track of then when they were on VHF especially during outages when my father was alive he use to do contract electrical work for ETSA before retiring he had a 10 ch scanner in his work bus that consisted of the local emergency channels as well as etsas work channel so he had an idea of what was happening if called up

A lot is done over data terminals now, so even though AEP has such a huge system, there isn't as much activity as there was years ago. and even years ago when they were on an EDACS system they used data terminals. But once they switched to the p25 system the typical voice traffic went down quite a bit. But during an outage, the trouble talkgroups are definitely active and linemen/etc are always verbally confirming with dispatch when a circuit is about to be brought online again after an outage. So, fortunately, there is still enough activity to determine what is causing the outage in my area (fallen tree took a line down, vehicle hit a pole, transformer blew up, etc).

When SA Power had their VHF system operational prior to going fully p25 encrypted they would be communicating with their linesman and patrol vehicles to see which line had a fault or was damaged this was relayed onto their depot in Mount Gambier to allocate resources however voice traffic was short and sweet not consistently active like it would be over there

SWEPCO Talkgroups Shreveport Area

5191 submitted as Shreveport Trouble (had to call their linemen out at work, saw the radio) even though it covers Bossier City.

5292 sounded like transmission trouble in TX (called "Western", then no answer, called "Dispatch", they answered and said Carthage PD reported a broken pole). Not sure what "Western" is.....

5203 sounded also like transmission trouble in Shreveport. I know it's in the db as the Lieberman PP, however they're talking about busted poles held on by a drop. At an address in Shreveport City (far away from the plant in Mooringsport).

Anyone else in the area monitoring?

Any able to confirm that they can see Harris aliasing?

It is active here in Ohio

Alias is set up as OHXXXX

So Ohio radio id 2004567 shows up as OH4567

You will need a Harris radio to decode these.

I would the two digit state code will follow to other states ex WV,KY,TX etc…..

Yep, I see them for both AEP Ohio and Appalachian power and it’s probably the case for all of the systems

DSD plus, SDR trunk we’ll pick them up. I think DSD-FME also does

We also need people in the following areas to confirm these sites as being online (we know they are based upon what neighbor peers say but do not have actual realtime monitoring confirmation. I'm sure there are probably a couple of other sites in the various states online, or at least I imagine so.

If you are near one of these sites it would be great if you could check with DSDPlus or something like that to verify the site online, it's SystemID, Site ID, NAC, and active frequencies.

1F7 63.63 Chatham / Blairs / Dry Fork VA
1F7 69.69 Buchanan VA
1F7 91.91 Asher KY
1F7 92.92 Hyden KY

1F8 39.39 Throckmorton TX

1F9 8.8 Cheyenne OK

I got a RTL-SDR V4 last week and running SDRTrunk. Now I can decode TDMA CC.

I don't think I was ever able to find Cheyenne OK site (before they went TDMA) because too many others on the same freqs.

Awesome. I just worked your Throckmorton submission. Great to have that elusive one marked. I took the opportunity to update callsigns and locations on one or two sites and to update the 1F8 wiki stuff.

There are still "licensed" sites for 1F8 territory that haven't been discovered online, but they are sites for which I hadn't seen any FCC activity for some years now and likely will never be on / were replaced by other sites.

I remember a few years ago something wierd in Abilene TX area sites. Then I noticed today this one apparently moved from Abilene to Hawley. Check the location in the callsign link.

I'm aware of that one having been one that was going to move. In fact that was on my radar when I was in the DB a few days ago. But some of the freqs are diff on the new license, and somebody really needs to copy all the active freqs from that site from scratch again.

I did update the location in the RRDB to reflect Hawley. But despite it moving to Hawley, it looks close enough to still be called Abilene and I'm betting they probably still reference it as Abilene, so I left it as Abilene in the DB.
