• 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:

The Golden Gate Bridge District seems to have completely reconfigured their sites/frequencies. Normally I receive Site 1 off Mt. Tam, however I am currently not receiving anything on those frequencies. I am receiving a control channel on 771.33125 (formerly a Site 2 frequency) which is showing as Site 1. All voice traffic is on 773.99375.

This new Site 1 is showing only one peer, Site 2 using control channel 770.25625 (formerly a Site 1 frequency). I am not receiving anything on that frequency from my location in Kentfield. There is also currently a test tone on 774.24375.

Maybe part of the work described as Project 1711 in the 2018-2019 budget?

Is 773.38125 still used by the District? I have it assigned to Santa Clara County by the Region 6 700 MHz RPC and also licensed by SVRIA for the Coyote Lake ASR. Not likely to cause any interference, but that's the only one of SVRIA's frequencies that has a nearby duplicate assignment.

Good find, that would explain it. Site 1 seems to be a larger simulcast cell incorporating most if not all of the original repeaters. I'm still trying to figure out the location of Site 2. Could be Sonoma Mountain or Bald Peak (Berkeley Hills). Site 2 CC has switched to 771.15625.
