• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Did you trying looking at the RR Database? I live west of the Dublin/CV grade but haven't monitored Caltrans in some time. The database shows Alameda and CoCo counties (800mhz) with a voting site in San Leandro. Here is the site that I'd expect would cover your area of interest:

I don't believe that trunked system covers the tri-valley. It's more for the 880 corridor (East Bay coverage).

Go to the CalTrans page and look for district 4.

The page I linked to for the OP says District 04 - South. Although looking again. the other option was District 04 - North and the page notes that the repeater is in Marin. Is there another page that you're referring to?

Yes. You linked the trunked system. You would need to go to the state page and select CalTrans for the conventional listing.

Ah yes. I didn't see that page. That should answer the OPs question just fine. I noticed the Sunol Ridge site/frequency. Right where he's needs. Thanks, kma371. I learned something new today too. I always thought they were trunked only.
