[Due to the loss of this info in the database, I bring you this...]
The Lawrence Livermore National Lab operates a Motorola 3.x SmartZone system (3600). All transmissions are digital only [IMBE]. The system does employ encryption but it is commonly used on the complex security channels (eg., 720, 736, 752, and 80). Site security is normally encrypted but will go clear once in a blue moon; usually to do roll calls.
The network is comprised of six sites not including the backup sites which are duplicates of the primary sites. They are for failures of the primary sites. Each site is linked via microwave forming a ring. This is for redundancy in the event of "service disruption." (Below, the site numbers in brackets are the secondarys)
The main site is located south of Sandia near Tesla Road. The next site is "Site 300." Site 300 is where they conduct explosive testing. To get to Site 300 you take Tesla Rd into the hills as if you were going to I580 or Tracy. The Lab system can be heard throughout Livermore and parts of Pleasanton. Site 300 is tough to receive though certain areas such as at the top of the Altamont Pass or in the vicinity of Camino Diablo & Los Vaqueros Rd. These two sites are the main traffic sites and are where most of the activity occurs. All sites are Quantar IntelliRepeaters.
There are four outlying sites with two using SmartZone's "Voice On Control" (VOC). VOC allows the control channel to become a voice channel temporarily; once the voice call is completed the channel reverts back to control. VOC is only used for low activity fill-in sites due to its nature. The two VOC fill-in sites are Crane Ridge, which is off Mines Rd, and one other site I have yet to identify the location for. It is most easily heard in the Altamont/Tracy area. Crane Ridge and the unidentified site are two channel VOC sites. Mt Diablo, which was once a single channel VOC site, is easily heard everywhere as it is located at the Navy Communications site on the West side of the mountain. Crane Ridge can be heard throughout Livermore and into the hills south of it. Since the three of these sites are low capacity sites their activity is restricted to specific talkgroups with higher importance. Additionally the radios are programmed with the Lab or Site 300 as the preferred sites so as soon as they can receive either they will roam off. Mt Diablo is actually a rather quiet site. Sometimes a stray electrician, security, or fire radio makes its way over causing some activity.
If you choose to listen to the Lab site you won't find much interesting activity but it's the site primarily used for Lab Fire if that's your interest. In addition to Lab Fire you have their security, encrypted of course, the shuttle and escort people, facilities, project management, and individuals that call themselves what sounds like WAHOO##. They seem to be related to Fire admin in that they do a lot of inspection related to hazmat and fire prevention. The people that sound like project management are one of the slim few who use private call (radio-to-radio or what Uniden stupidly named "I-call"). Outside of normal business hours the system is dead (excluding Security). I have yet to listen to Site 300 for long periods of time but it is quite busy with traffic which is NOT repeated on the Lab site. If you are looking for something interesting Site 300 would probably be your best bet.

IIRC, Project management people were in the 1100s and/or 1500-1600s. They're more active on private calls.
Last note: ATGs are used frequently during the day by Lab Dispatch. Fire Dispatches are MultiSelects a majority of the time so the ID the dispatch goes out over can vary. Sometimes it's Fire 1, or 2 or Fire Admin.
I'll update this as needed. I've got an article somewhere that talks a bit about the beginning of the system.
Lets all thank Clarence, the system's manager, for basically spurring me to make this information available. Thanks Clarence! :twisted:
