I can't imagine that it would hurt to try, certainly. Uniden scanners aren't that difficult once you come to appreciate how they operate but since I haven't owned one for a long long time now since I had a BC246T I wouldn't think they have changed all that much. If you create a new system and just use the CC Only capability and use that 853.9000 frequency for the CC it should get you going - you may not see all the TGIDs labeled since they'd need to be added manually (maybe?) - I was thinking that altering something in Sentinel before uploading it to the scanner would cover that but perhaps that's not how Sentinel works but again my lack of having a real actual physical scanner nowadays precludes me from such experience.
The Home Patrol is something I have zero experience with so that makes it even more difficult to offer assistance so hopefully someone else that owns one and is more familiar with it might be able to help with this situation.
I saw some activity from HPD on both the 853.9000 and 859.9375 frequencies/sites earlier - I wasn't actually monitoring for audio, however (didn't have DSD+ running), and I just checked again with Unitrunker and I still see activity. As soon as I fired up Unitrunker and enabled the Signal receiver wham (on 853.9000), I picked up several calls on HPD Main Dispatch (TGID 3603) and HPD Information (3609), now I'm seeing some hospital traffic as well which I've never seen on the P25 system, specifically UMC Trauma (2755) which until today I've only seen on the analog SNACC system. Now seeing NLVPD South Dispatch (2293) as well.
Switching to 859.9375 I see a lot more activity on the NLVPD South Dispatch as well as HPD Main Dispatch activity as well - I'm sure there's a lot of other stuff as well but as I mentioned earlier I just don't have everything properly labeled at the moment.
One thing I don't see on either of the sites: any Fire Department/EMS activity whatsoever, from Clark County, Henderson, North Las Vegas, or Boulder City so like I mentioned earlier they could have wanted to get the PD traffic moved over and solid before they start in on moving those aspects over. Not one call or attempt at a radio joining the system so far on any of the fire related TGIDs.
It'll work itself over time I'm sure, but it does seem odd if you can get NLVPD traffic that the HPD traffic isn't happening either, I'm going to leave it to someone more knowledgeable about those scanners to figure out.
