Hey guys, I've been having a blast figuring out my local LTR systems since I got my new Pro-97 a month ago, but didn't want to post incomplete information to the database until recently. In addition I wanted to share it here for everyone to check it out if they wanted. It's been a really interesting process, because none of the systems seem to be licensed (or span a huge amount of multiple licenses) in the FCC database and it's been challenging waiting for just the right peaks in system activity to determine what a "TO" channel is by band-scanning for it long after I noticed the first "trunk-out" on the screen and was aware which channel I was looking for. It can be pretty maddening at times but a totally entertaining challenge (especially IDing the users) and I'm happy to share my findings with you all!

(This system was already in the database but it appears a lot of the freqs are from other systems, so until I can verify each one this is an independantly confirmed version of it.)

There is also a CH12 TO! There may also be a CH02, unless it's related to CH09 and 09 turns out to be a different system.
461.600 CH09 H is either part of this system or the one above. It's sole talkgroup is 0-09-005, a Tow Truck company. The sound quality is identical to this system hence why I've put them together.
Talkgroups:
0-14-007 - Tow Trucks
0-14-008 - Probably a 2nd channel for the above Tow Trucks
0-15-014 - Tow Trucks (Marin Co)
0-15-019 - Unknown Base
0-15-051 - Unknown (Perhaps a Mobile w/ -056 & -057?)
0-15-056 - Unknown Mobile
0-15-057 - Recycling Truck (Possibly same channel as -056 and -019)

0-15-071 - Garbage Trucks in Richmond Ch 2
0-15-079 - Unknown (database says SS Comms?)

0-15-085 - Shuttle Buses of some kind. Airporter? Marin Door-2-Door vans?
0-15-111 - Spanish Speakers
0-15-117 - Tow Trucks
With the amount of users, and knowing that the system is incomplete, I'm really looking forward to figuring it out.
Here's a totally unknown one, extremely strong repeater and sound quality would appear it's also on Big Rock Ridge in Novato.
