Welcome for your first post

LLNL 
https://www.radioreference.com/db/sid/6781
actually has 10 known (reported) Sites, the main site with 8 frequencies

Site R-001 S-009 has only 4 known frequencies, what did you find for a 5th
transmitter frequency?
https://www.radioreference.com/db/site/18851 

BTW the NAC for that TRS has a unique NAC per Site with 3B0 being the SysID

TG 120 was reported as P25 but not ENC, is it Full Time ENC or Part Time ?

P25 stuff from San Francisco
Here is what I heard.  Hope this is useful.
Lawrence Livermore system
NAC=3B0 for the Trunk system 
NAC=3B9 site 1.9 channel is 4-1971 407.1875MHz
TG=120 RID=705xxx enc
TG=120 RID=705xxx enc
Looks like this site has 5 transmitters
