Most of the traffic will be heard on the main Livermore Lab site, 300 and LBL. Radio Site 3 is located at both Site 300 and rebroadcasted at DLA Tracy. The other sites are fill-in sites that restrict a lot of traffic; i.e., only important stuff like Security or FD will come over the Mount Diablo site though many LBL TG's do too. Crane Ridge is regularly active with traffic that's roamed off 300; it's located South of the Lab off N. Mines Road. Site 8 is/was located on the property of the Defense Distribution Depot (now DLA) San Joaquin in Lathrop.

LLNL Security is encrypted 98% of the time. Once and a while they'll intentionally go into the clear and do roll-calls, then go back to secure. Supposedly radios are rekeyed via OTAR. The OTAR frequency is unknown.

Private Call (aka I-Call) is used a lot by what sounds like Project Management people at the LLNL main site. ALCO Dispatch (located at the LLNL main site) typically MSEL's a bunch of groups in its dispatches (Usually 496, 560 and 1008) so make sure you have them all in if you are in ID Scan or Closed Mode. During normal business hours the Lab site is pretty busy but outside of that you'll probably hear/see just the facilities guys chasing alarms, FD, or Site Security.

This network has backup sites for Site 1 and 3. Since changes in communications management have occurred the sites are no longer cycled for redundacy testing.

There are a two fire stations on the Lab property; as of the ALCO contract agreement they are known as County Fire Station 20 and 21 (formerly 1 and 2 respectively). They can often be heard on ALCO Trunked TG Control 2 and Fire Tac 6 in addition to the Lab's Fire TGs. [If someone could provide more detailed unit numbering it would be helpful!]

DLA Tracy has a Federal Fire Station on-site. Their vehicle numbers are Chief 26-2, Engine 26-2, HAZMAT 26-2, Ladder 26-2 and Truck 26-2. DLA Sharpe is assigned Engine 26-3 and Truck 26-1. Both departments are dispatched via a DLA unified 911 comm center for on-depot operations or for off-depot operations thru LIFECOM on San Joaquin County Fire South channel. In the DB see San Joaquin County Fire, specifically South Dispatch and Command.
