I drove thru Calhoun Franklin Gulf Liberty (FL) counties didn't see anything on the P25 side. I did see 1 TG on the analog system (Tallahassee).

random neuron firings here... but.
we have a "new" control channel up on 860.3875 and one on 857.3875 -- monitored in east central florida.
neither DSD+ nor Unitrunker will decode these CCs. Suspect they are in "test pattern" mode or (??)
just keeping an eye on them for now -

btw - a good start on the Duke Energy Florida licenses are:
WRJI625
WRJH815
WRHZ715
note, I had to search XXX.XXXX MHz in >>NORTH CAROLINA<< (Duke HQ) because the FCC website won't let you drill down and search via the transmitter location. All of those licenses above have florida locations in them and they are relatively current (~1 year old)
also worth noting that these are (from my quick look) -- all 800Mhz licenses for Florida... not 900.

I went to the counties I travel thru and found 800 a month ago I added the 900 to see any digital pops up when I go thru certain areas. I'll find out next month see if anything pops up on 800/900 for digital side.

Duke Energy P25 System
That's a form of beaconing. Once the system is live, that switch to the FCC CWID burst usually. Yes the timing changes etc. Beaconing is almost universal on systems from what I have seen. Like that NXDN system Lutheran has, the Indy site for it is still just beaconing with no cc of any kind...
The PDF in this post has all of the call signs, frequencies and locations for each site that should be broadcasting a 'test' signal.
The system will be fully 800 MHz and will consist of a zone for each geographic area that will all be tied together for systemwide roaming.
INDY72
Monitoring since 1982, using radios since 1991.
The actual answer is, and not being a smart azz, "Until they are ready to take the site/zone/region live." I have seen systems like the Entergy conversion to P25 have sites testing for only a week or two, and other sites in that same "zone" bee testing for months, then the whole section went live. I have seen sections on the VIPER, and SAFE-T P25 conversions that took only a couple of months, and other parts of those same systems need to be shut off and redone due to connectivity issues, then back to testing for a while before going live.

I believe they are still in the build out stage of the microwave back haul system so until that is all connected they will likely run a 'test' signal on the P25 sites as they come online.
They requested an extended build for this system and part of that is showing that they are making progress, these 'test' signals are showing the progress.

Here is an updated list of the sites being reported as built so far.
just FYI ---- the Duke Energy site in Christmas, FL (somewhat near me) >>> 857.3875 (WRHY215)
has been confirmed as a TDMA Control Channel - currently not decodable with DSD+/Unitrunker/OP25 ... and not trackable with any scanner (yet)

Slowly making progress.
Duke TDMA CC site in Florida:
Duke Energy P25 Trunking System, Various, Multi-State
Duke Energy P25 Trunking System Profile
www.radioreference.com
This will be a multi-state interconnected network so I recommend dropping Florida from the name on the P25 system in the database.
i really was on the fence with this one and made the name reflective of the current Duke analog system; but I'm always open to ideas. I'll edit the Florida out of the name.

How were you able to determine the WACN, or Sys ID?
Take a look here:
P25 TDMA Control Channel decoding -- requesting help from experts
Ok, was finally able to figure out the base frequency and offsets so I can help verify the site summaries. I still haven't figured out the CRC, so this summary has an X at the end of the line if it occurred multiple times in the file, or (not confident) if it wasn't consistent. I've also...

Analog already is interoperable.
So this whole TDMA control channel thing, does that mean they can run separate different control channels on the same RF frequency?
It means the CC can also have a voice slot on the same frequency as the CC. Not two CC's on the same site/frequency. Think like Trunked DMR CC's only P25 instead. (2 slots)

Understood. I do find a lot of P25 systems seem to have gobs of excess capacity (too many frequencies) for how much activity on average.
Being pretty close to the low level stuff and looking at earlier documentation, I will say the new control channels could also easily support 2 separate voice channels simultaneously on the control channel frequency in addition to the new control channel bursts. To answer your question, it does not look like multiple control channels. It looks like some new information (control channel) added to the TDMA channels that have been there from the beginning. The new information is handling the job that has been previously done by phase1 control channels only.
