Uniden made the conscious decision to have Sentinel ignore trunked systems that didn't tick all required boxes. No talkgroups was one such condition, as was the lack of LCN info for other system types where that's a thing. The reasoning was that there is no way to enable ID Search mode in the full database for the HP/x36/SDS scanners, and so they intentionally chose to keep things dumbed down. I recall Paul once explaining that they made that choice in order not to have people wondering why a particular system was found in Sentinel, but wouldn't scan anything. I know many times over the years it was requested to have the systems included so that they could be easily appended to a favorites list, which could have ID Search enabled, but obviously that never happened (and almost certainly never will).
In any event, it's a pretty simple process to create a favorites list, create a new system within that list, add a few control channels, and enable ID Search to start listening immediately. Once the talkgroups are populated in the Sentinel db on Monday, the entire system can be pulled down into that favorites list.
Many of us were doing this back in the day before we had scanners/receivers capable of computer programming, and we'd have to spend countless hours sitting on the couch programming everything one keystroke at a time directly into the scanner. That was tedious enough with a 100 channel scanner when all you had to do was enter frequencies, then along came 1000 channel scanners with alpha tags that had to be hand-programmed...a real mixed blessing! Kids these days are spoiled with automatic database pulls and 1 million entries instantly available on a microSD card!
Oh yeah and...get off my lawn!
