So in other words: talk groups on trunking (or otherwise organized systems) which no one has as of yet identified, validated, and submitted to RR for inclusion in the database? That makes sense to me, so hopefully you (or someone) will validate that understanding.
This is something that has been kicked around before. The original Home Patrol scanner was promoted as one that someone with zero radio monitoring knowledge base could hook up to power, set their location, and update the database, then turn on the scanner, and listen to their local systems. Systems without talkgroups weren't included in the Home Patrol's database, since there was noting to listen to. Yes, those of use with some knowledge of how systems work would know to flip the system to ID Search,and let it find active talkgroups. But we're not the original target market.
Another category where a system would not be included were those that had no LCN's (logical channel numbers). When the HP-1 came out, that mainly would have been LTR and EDACS systems. (That was well before later models, starting with the x36HP series, had firmware upgrades to allow reception of DMR & (later) NXDN systems.) With few exceptions, DMR and NXDN systems need correct LCNs to be monitored, so, at present, those are not included in the databases provided for Sentinel.
As has been discussed in a different thread, the suggestion has been made to Uniden (via Jason Houk) to see if those 'unmonitorable' systems could be, somehow, included in Sentinel's database, to enable those of us with an understanding of how things work could more easily load those systems, and work on filling in the needed information using ID Search, and the LCN Finder utilities in the x36HP & SDS series scanners. (The HP-1 & HP-2, if they have the "Extreme Upgrade, also have an LCN Finder ability.)
