The frequencies are entered into the RRDB incorrectly, possibly making the radio inop if the ARC software only enters the two control channels marked in the RRDB. Since this is a Harris P25 system, it can use ANY system frequency as the control channel, thus ALL the frequencies must be programmed into the radio for it to work reliably - you should verify and enter any missing frequencies into the software by hand and reflash the radio. If you are so inclined, you can use some free software and a $25 SDR dongle and map the system and further verify the RRDB data. I will submit a note to the RRDB admin for your area to fix the entry.

In the ARC-XT Import window, under the Trunk Options tab, check the box to Import All Control Channels.
He will need to enter all system frequencies manually until the RRDB entry is fixed, but good tip.

In ARC-XT you have 3 choices: Primary Control Channels, Alternate Control Channels, and All Control Channels. Another member said that when he checked the box to Import All Control Channels, it entered every frequency as a control channel. It would be interesting for KD4DOB to try that and verify if that is true.
Might work, worth a shot. He should be able to tell if it worked before trying to load the programming into the radio.
Thanks for your help. I have attached a pdf of my set up. Of course this is only one of probably over a hundred I've done over the past two years.But if you can tell what's wrong wih this one, I'll know if I've tried what you suggest.. I did watch the Scanner Guys carefully (very good) and it was exactly what I have been doing to the "T". . I don't give up! I just might be a bit more determined this time though.

Just to clarify, while some Clearwater TGs are encrypted, there are many unencrypted, and certainly "listenable".
I would try making a custom entry into the software, add the CC's, and leave it on ID search. You wont get the names of the TG's but at least you'll be able to hear it and you can then add the TG names once you confirm it works.

The Clearwater system is not tagged as simulcast.
However, if you bore down into the Site 10 details, it does appear to be a two site Simulcast system.
Here's the map of the transmit tower locations:
Looking at the license, the frequencies are identical for both sites. While the majority of the simulcast systems we see in the database have more than two sites (some have a dozen or more), if the OP happens to have the bad luck to be in the wrong place, it could possibly be a factor.
Since it is a Harris system, any of the frequencies could be used as a control channel, at any time. All of the frequencies tagged as FB2 on the license should be entered for the site.
KD4DOB, look at the map and find your approximate location. If you are using the antenna that came with the scanner, set the scanner on a table, desk, or other flat surface. Then get a baking pan or sheet, any large metallic item, and set it beside your scanner, with the sheet or pan shielding the scanner from the farthest of the two sites, blocking it's signal. (Ot should be large and tall enough that the scanner's antenna does not extend above the signal blocking object.) See if that helps receiving the system. If so, then you may need to consider a directional antenna for use at home. Of course, that is not practical when mobile, but at least it would eliminate one possible issue when monitoring from a fixed location.
As already noted several times, some TGIDs are tagged as encrypted, so you would not be able to hear them no matter what was tried. But, as also suggested, running the system in ID Search, not ID Scan, would widen the pool of how many talkgroups you might be able to hear.

The FCC licensed emission type is 9K70D1W, which is Harris' flavor of P25 LSM for simulcast systems:
I'm hoping the reason why he is unable to receive this system is because the cch has rolled to another frequency that is not programmed in his radio. The RRDB has been updated which addresses that problem.

Wow! Finally making some progress after two years working on it myself. I really appreciate these last threads! I have reached out trying to make RR realize there is something wrong on their end. After Years of successful downloads on either of my scanners with no problems and finding that it also doesn’t work in my other scanner, I knew it wasn’t me! Whew. Now to try some of these last suggestions. Did you mean that the only problem was the two control channels?
You've been trying to load this system for 2 years?
No, we are trying to eliminate possible problems. I know there is a feed of the Clearwater system that works, so it is doable.
There are at least 11 system channels that should be loaded into the radio.

Try checking the box to Import All Control Channels under the Trunk Option tab on ARC-XT to see if that loads all of the frequencies.
Yes... I worked forever when Clearwater first changed to p25 (at least two years ago) Bought another scanner. . Revisited it probably ten times with varying degrees of obsession and this time, I was determined. Being a computer nerd, Ham and scanner person, I decided this was a way to spend my COVID isolation. That was a month ago! Perehaps a mistake. For the past two weeks it has been non-stop. Not only because I am a determined cuss but because I live here and it's the only System I can't have. The frustrating part is that not Butel, Radio Reference or Scanner M*(*((* wanted to help.This community is GREAT!

Adding the system manually doesnt work?
Edit favorites list -> click top "branch" -> green "+" > dropdown menu, click P25 X2 TDMA -> create site, department, check "ID search" ON

I live in Dunedin fl north of Clearwater the current active control channel is 855;96250 hope this helps!
