Site 4 is still being built but it's planned coverage area is Albany. I think only the Glen Dyer location is active.

I can't get over how HUGE that Patterson Pass tower is. For the area it definitely sticks out. The adjacent site/tower where Sandia Labs has their repeaters is dwarfed in comparison. Across the street is an amateur site where the LARK repeater is at I believe.
And in the photo you can see they're using a panel antenna so the RF is focused toward the Tri Valley area (and so us Valley folks get basically nothing).

Which tower is on the south side of the freeway going up the grade on 580 at Patterson Pass that has the blinking white light?

So here's a couple things I need flushed out.
1. Does anyone know if we're going to have to listen to every cell site in order to hear ACFD or EMS or will they simulcast several cells on different cell sites.. I'm assuming (maybe I shouldn't) that it will be sort of like how it is now where the local PD's will be on their respective cells and not simulcasted while ACFD, ACSO or EMS will be?
2. PDF for NOV says cutover date of DEC 11, 2011 and finish date of June 12. Does that mean they will be using the system and majority of traffic will be on the system next month and in order to listen we need to listen to EBRCS or can we still listen to the current 800 system and COCO conv. channels until June?

The December 11th, 2011 cut-over date is only for the dispatch console systems Ben96cal. The system is due to be live in June 2012. So all you would hear on the system now is radio techs.
Well if we are hearing the control channel, shouldnt we be hearing all of it?

So in your opinion if I want to listen to fire in Coco and Alco I will have to be able to pick up all Cells ie. Alco East, Northwest and Southwest, Coco Central, West and East? Doubtful that let's say Alco East would transmit Alco Southwest's traffic....
My guess would be wide area talkgroups, like sheriff, county fire would transmit on all sites.
Kind of like it is now on current system. You can only hear San Leandro on the local sites. But you hear fire/AMR on the wide sites.

That's for the high KV DOE/WAPA power lines. The Patterson Pass site isn't visible from the freeway. Maybe once you pass 205 heading toward I5 would you maybe be able to see it.
So you're saying you hear Site 2?kma371 said:
Hearing AlCo Fire & EMS traffic will depend on how the system is configured. You ask about 'simulcast' (multiple sites on the same RF frequencies acting as one large cell) but the context of your question relates to 'multicast' (same information transmitted across multiple sites on different RF frequencies).
In most larger systems, talkgroups will not be transmitted (anywhere) unless there is a user radio affiliated with that particular talkgroup registered in that particular cell, and that talkgroup is permitted in that particular call.

Lots of testing chatter on the east site for Alco this morning testing TG's 1-7
I'm hearing that as well here in Fremont. Radio ID's being used: 4319002 & 16777207. BTW seems like the RR forums time stamp is off by two hours. Appears that it was set ahead instead of behind re standard time last week.

Sounds like they've got 7 radio's side by side doing multi site TG testing...
Hayward
Question about Hayward... did they decide to leave the EBRCS?
Based on this:
Hayward City Council - Tech Apps Comm Report on EBRCS 11-19-2008
Hayward had good reason to stay out of EBRCS. After review of those documents and recent EBCRCS newsletters, there appears to be a conflict of information. The EBRCS site lists Hayward as a participant, but the newsletters do not list Hayward as receiving dispatch console upgrades or installations. It does appear as if EBRCS got their installation on Hayward's Garin Water Tank and possibly Hayward PD, however.
Hayward... are they in, or out? I can't tell...

Hayward PD is in as it uses Alco trunk currently for such things as NARC... HFD is out as it plays by it's our rules and is actually redoing it's frequencies, ie. adding tacs....
Hmmmm... HFD had serious reservations about going digital per the 2008 report (audio quality), so it makes sense that they are not joining.
How is HPD supposed to move to EBRCS without a dispatch console upgrade? Forgive me, but I don't see how HPD using ALCO narc channels means they are moving to EBRCS.

This is only conjecture but if the municipality is already on the existing trunk system it would seem unlikely it would leave. HPD won't use the system as primary comms but it will be on the system.
