I just posted a few talkgroups for Aiken County.

If anyone can confirm additional talkgroups for SCHP Troop 7, Augusta-Richmond County, Bamberg Co (they might be all conventional still), Orangeburg County, and Aiken County, that will be very helpful.

We have most of the Troop 7 sites identified, but it's always helpful to get confirmation that the active control channel frequencies are accurately indicated.

As others have indicated, it is probably reasonable to assume that Aiken County talkgroups are in the 20500-20999 range. Augusta-Richmond County is probably in the 55000-55499 range.

Brian here are TGIDs that I heard this morning:

  1. 20505 - Aiken County Sheriff (Possibly Warrants - Civil Paper Servers)
  2. 28501 - Transportation - Possibly Best Friends Express
  3. 28503 - Transportation - Possibly Best Friends Express

I heard no information to confirm that the 28501 & 03 are Best Friends Express, but they were discussing pick ups and drop offs.

Assuming the TGIDs are going up in numerical order, 20505 should be ACSO Channel 5.

All the traffic I previously heard on Channel 5 seemed to units out at the courthouse. It was labeled as DUI Enforcement previously on the Motorola system but I've never heard radio traffic that would suggest that.

As for all yes the entire system is converting to p25. Not just tg. The ENTIRE SYSTEM. The current Palmetto 800 is analog based with digital tgs on it. This is upgrading to completely digital.

Union County is in Troop 4, but for the purposes of this change, its radio tower is switching to P25 with Troop 2 September 25-29. The original dates listed that you referenced in your message are no longer valid.

And yes, all county Palmetto 800 towers are switching to Palmetto P25. All talkgroups changes as part of the transition. While it's fine for folks to continue submitting Palmetto 800 talkgroups and other information, it all changes with the change to P25.

I'm getting all the talk groups for the Aiken County sheriff's department and the SCHP, but I'm receiving nothing for SCE&G. Did they go to P2?

Also, on the Johnston tower, the only two analog talk groups I receive now are 48944 Greenwood SCHP and 45840 Orangeburg SCHP, none of the digital TGs that were there like the Edgefield County Senior Citizens Council. In fact the two SCHP TGs are the only thing I'm picking up at the moment.

I'll be glad when this is all over, but it has been fun getting and finding what I can.

Can the first post be changed to reflect the new dates? I'm curious about Spartanburg County and changes buried inside the thread confuse people when they see the first post and it's wrong.

Thanks,
Scott

Does anyone know if adding both site frequencies from the new P25 and Palm 800 sites for one individual site will make any difference in the amount of tgid's one could pickup?
Ex. Sumter site frequencies from the P25 and the 800 sites added into one P25 system.

It depends on how your scanner is programmed and how it handles selecting control channels. With the PRO-106 "family" of scanners, you can choose ROAM or STAT and that will determine whether the scanner picks the "best" control channel and sticks with it, or scans each active site during each pass. The PSR-800 family of scanners only have a "Roam" setting and attempts to pick the "best" control channel and stick with it. Programming each site as a separate system can mimic the "STAT" setting.

Other radios handle control channel/site selection differently.

To properly answer here: These are 2 separate systems and MUST be set up as such. When you set up the system type it will treat ALL sites programmed as that type for that system! Only in the oldest P25 scanners like the PRO-96 did you not set a system up as Mot and it also covered P25. Newer scanners don't work that way. With the exception of maybe the Uniden BCDX96T family? The XT ones you would set P25 standard for the new system and MOT for the Legacy Palmetto 800. But all scanners will only use the cc they find for the site programmed first. If it finds an legacy cc it will track the legacy system. If it finds P25 it tracks that. That is why you never put both in same system if they are standing both up side by side.

Milf....I think another notation that's needs to be added to the database is the County Simulcasts (as part of the State core) vs the actual state system carry different talkgroups. I can predict that a lot of people are going to have issues if they just download all sites from Sentinel or EZScan and try to monitor SCHP even in the County they are in. I've brought this up before that in Charleston for example, there are two separate cells (one County and one State) all part of the State core. So if you program in both and the scanner locks on that control channel for County you will not hear SCHP...you will have to build two separate Palmetto P25 systems in your scanner. So knowing what sites carry what traffic may be helpful.

I completely agree with this, and as such I've tried to identify sites 10, 11, 12 and 13 with "Charleston County" tag in the site name, whereas sites 9, 58 and 59 have a "State" tag. If you have a better suggestion, I'm open to it.

At this time, there is no way that I'm aware of to tag a talkgroup group with particular sites.

I have noted this weekend that talkgroup 9611 (SCHP Berkeley/Charleston) is carried on site 10. Beyond that, there doesn't seem to be much overlap.

I'm not sure that all simulcasts fall into this "separate but same" scenario like Charleston. Beaufort does, perhaps. But I'm not sure yet about Sumter and Florence. When I passed through Sumter County a few weeks ago, its Palmetto 800 site was still active as a 3600bps control channel - it's not supposed to change until the end of August. Some have reported hearing more talkgroups on the Sumter simulcast P25 site, including Lee County. So maybe the sites in Sumter will "merge."

I haven't had any confirmation that the old Effingham site in Florence County is on the air as a Palmetto P25 site. It didn't show up as a neighbor site to Kingstree as I would suspect when I passed through there a few weeks ago. So perhaps the Florence site has also "merged" with Effingham.

I expect the simulcast sites in Richland, Lexington, Spartanburg and Greenville to transistion to P25 just like any other single site, much like Georgetown. Anderson will be another interesting one to watch in about 7 weeks.
