Yes I have the Extreme Upgrade Grade I heard one channel on analog one day talking in the open it sounded like school radio traffic about which kids missed or where on the wrong bus. I left it on LTR system analyze for 24 hours no hits. I then tried it again on a conventional analog system got 15 hits with the CW ID only on a Friday night. I tried putting the frequencies in order and giving them LCN numbers 1 though 8 with one being on the lowest freq and 8 the highest freq. Any other suggestions would be very welcomed darn wish the HP2 had NXDN going to have to upgrade to something else this is getting too expensive.
At this point, you still don't know exactly what system type is in use. See the attached file. I zipped it to meet forum requirements for attaching a file. Download the file to your PC. Once you've done that, use Windows Explorer (File Explorer on Windows 10), or a file utility such as WinZip or 7Zip to extract Cibola County.hpe from the zipped file.
Import the file into Sentinel for your HP-2. I would leave it, for now, as a separate Favorites list, instead of adding to an existing list. Download to the scanner so that you can try them.
I have used the FCC license information to create three systems using those frequencies. The first is Conventional. If you can at keast hear some occasional voice transmissions, than that would mean that, at least, they are not using NXDN. That would be good, since the HP-2 cannot do NXDN. Listen to the conventional system & see if you are getting some activity. If one of the programmed frequencies has a steady noise, resembling an idling diesel engine, then they may be using a P25 trunked system. The third system in the file is set up as a P25 system. If it is indeed that system type, you do not need band plans. The scanner gets whet it needs from the control channel data,
The second system in the file is set up as LTR. You would need to go through the Advanced Options & Advanced Menu on the scanner to activate the LCN Finder. Leave the scanner in the LCN Finder mode as long as possible, to give it the best shot at finding them. Since you were hearing comments about 'who missed the bus', the main user on the system may be a school district. If that's the case, then likely you will hear little to no traffic over this holiday weekend, nor much at night. Try running it starting Tuesday morning, when school activity should be much more frequent. More on using the LCN Finder can be found here:
More details on the Extreme Upgrade are on Uniden's website:

You can find the online manual for the Extreme Upgrade here:
Note that while Uniden's documentation tends to reference the HP-1, the screens & capabilities are exactly the same for the HP-2.
I set both the P25, as well the LTR trial system, to ID Search, so that it can receive anything that's active if they are using LTR or P25.
