American Electric Power (AEP) P25 WACN 92715

[INDY72]

I will take another listen to the sites I can pick up near me now that I am back home. Will see what I can find this weekend if they are live or still beaconing test signal.

 

[firemantom26]

Site 109 New Concord, Ohio is on line now. Submitted to DB....

 

[INDY72]

Plainfield, IN still test signal. Checked with Pro96Com, and UniTrunker....

What's the license on this Plainfield IN site you are referring to?

OOPS wrong thread... LOL Please delete.. I was checking Duke's new P25...

Quanah, TX 1F8 93-93 is showing a new neighbor.
1F8 88-88 855.9375
Probably FCC Callsign WRMP502 (American Electric Power Service Corporation)

Thanks, Tom. I added 1F8-88.88 to 1F8-93.93's peer/neighbor list

Mike I'm able to receive the Abilene area this morning.
There are two sites licensed in Abilene.

Somebody (wasn't me) submitted site 55-55 to the DB but this appears to be wrong.
There is an EDACS CC on 856.2875 site 1 LCN 2 which matches the EDACS listing in the DB, and nothing on the other frequencies.

Also slightly OT The EDACS system shows a site 19 in Abilene with one freq 854.8125 CC which also appears to be wrong.

Hi Tom,

The Abilene info was submitted on 8-22-2020 by a person who appears to be a regular submitter of legitimate information. I'm not doubting you, but I'm not inclined to remove 1F8-55.55 from the DB unless somebody can get a copy on it from one of the other locations that happen to license all three of the same frequencies.

Rather than simply wiping Site 1F8-55.55 out of the DB, I'd rather see some people in Texas figure out what 1F8-55.55 really is. Surely there has to be some people in Texas that can do this.

The only licenses that I saw in Texas listing all three of the freqs that were submitted for Abilene are:

memphis        hall        856.2875    857.2875    855.6875
abilene        taylor        856.2875    857.2875    855.6875
abilene        taylor        856.2875    857.2875    855.6875

So maybe Site 1F8-55.55 is actually Memphis TX (Hall Co). However, if Memphis is 1F8-55.55, then one would expect 103 Wellington and 93 Quanah to list it as a neighbor.

No neighbors were submitted for 1F8-55.55 at the time of submission, and Site 1F9-43.43 Lawton was submitted by the same person at the same time (and it apparently is a correct site).

To add to my previous reply, I do agree there is an issue here -- and that 1F8-55.55 is likely not Abilene. In fact, the same person who submitted 1F8-55.55 as Abilene with 855.6875a, 856.2875c, 857.2875a also submitted, on the same day, a bunch of additional P25 channels for the Abilene Trunking System ( Abilene Trunking System, Abilene, Texas - Scanner Frequencies ), and that submission included:

Channel 0-498: 857.2375 SCC DATA
Channel 8-996: 857.2375-1 VOICE
Channel 8-997: 857.2375-2 VOICE

And I'd say its a pretty low likelihood that both the Abilene Trunking System and AEP P25 Abilene site would be both running 857.2375 .

So maybe i will remove Abilene for now. I don't _think_ anybody has reported talkgroups down in that area based upon listening to the Abilene site. Not sure what to do in this particular case though.

I'd be interested in what you and other think should be done in this case.

Don't hold your breath on that.

I can't receive stuff that far south very often.
I haven't been able to receive a site 55 on either the TX or OK systems and haven't seen it as a neighbor so I don't know what exactly is going on there. There are two sites with locations called "Abilene", one on a 180' tower downtown and the other on a 300' tower on the big hill south of town. They each have 4 different channels and 5 common channels. One is EDACS site 1 and the other is 19. I never figured out which is which. I don't know which one is the P25 site if it really exists.

As far as I can tell the Lawton site is accurate. I don't know if you as a db admin can look back at all the submissions but I think I submitted updates after it was originally added because it started populating more alt CCs or something else was wrong or changed.

I was able to run Unitrunker on the Abilene city system this morning and 857.2375 really is one of their channels. I got a VC hit on it this morning and I think it was the active CC a while back. Lately the CC has been 855.2375 the past few band openings. I'm not sure how often it changes.

The more I think about 1F8-55.55, the more I think:

1. It is possible that it is online and low power
2. It is possible it was online for testing but then taken offline
3. It is possible that they decided to move it to another location

When Ohio's part of the system was being built out, they brought a site online somewhere up near Cambridge OH (I forget which site it actually was). Then, after some time that site went down and the site came back up in a different location with a different site ID. But we knew it was the same site that was previously online in a different location because at the new location it was still listing all of the old site neighbors that no longer made sense at the new location.

And, @firemantom26 and @n8jsw can vouch for this, many sites came online with the CC advertising either a bad alt cc (not assigned to the site) or one more alt-ccs that were proven to still be active on the EDACS side during the transition. So we can only put so much stake into the alt cc's until everything is online for a given area and cut over.

So I'm not faulting the submitter of the original data a tall. Site 1F8-55.55 could have been on in Abilene, and it could have been advertising an alt CC of 857.2375 (that would normally conflict with Abilene Trunking System) but simply never had any activity occur on that freq (and thus no interference, no harm, no foul).

Still don't know what to do about the fact that 1F8-55.55 is in question now. Let's see if we can rally somebody close to Abilene to get the real scoop on whether it's currently online or not.

Yeah I'm not going to hold my breath. But, I'll try and reach out to the original Abilene submitter. I don't know if he is local to Abilene or if he pulled it in during a tropo event as well. So we may not get any satisfactory answer on the state of / location of 1F8-55.55 for a while.

I'll dig around on the forums and see if I can find a post by somebody who claims to run trunking/monitoring software and then I'll reach out to ask them if they are willing to help. There has to be somebody on RR who lives in Abilene. I mean I live in a county of 25,000 population and there is at least one of me here sleuthing. Abilene is 5x the size. One would think there has to be a couple of people living there who are capable of finding out for sure what is up

There are multiple P25 CCs on 854.8125.
I know one is in Quanah and the others are licensed at Shamrock, Memphis, Aspermont and both Abilene sites.
For a while I quit picking up the Quanah one and was getting at least two that appear to be coming from the SW but not able to decode them because of interference. Might have also been something else besides AEP.

It's a real PITA when that happens. I know @fiiremantom26 runs into that issue all the time up here in Ohio when trying to check for distant AEP sites coming online. He knows there is more than one active CC on a given freq, but the one he doesn't need is always the strongest lol.

Is it acceptable to just mark all the frequencies as voice channels until we figure it out?

Probably frowned upon somewhere down the line, but that's what I will do. We know 1F8-55.55 was online and existed so I would hate to remove it from the DB after it having been in there so long. I'll go ahead and just remove any suggestion of control channels on the site for now (but will note in the site notes what they were before I changed them).

You got that right Mike

Oh yeah, the same thing on 859.2875. I know one is probably Denton County but not sure if the others were AEP.

 

[nd5y]

I did this repeatedly and it is still trying to populate and delegate 1F8 or someting and crash.
I had something similar happen with one of the other western OK sites with a TX neighbor but it quit crashing because conditions haven't been good enought to receive it since then.

If I can't figure out what's going on and fix it then I will probably give up and stop providing updates.

I fixed this. When I start Unitrunker it always shows 1F9 delegated to 7FFFF-FFF. I have to manually select 1F9 and delegate it to 1F8 before I decode anything on either system. That makes Unitrunker behave properly but for some reason it won't save it.
