It's not confusing. Oakland PD is noted to be using the EBRCS on the Alameda County page. It's been like that for sometime.
I think the confusion comes from your understanding of the system NAME vs the modulation type.
"Oakland P25" refers to the system name. That system is no longer being used by Oakland Police/Fire and channels previously used by Oakland Police /Fire have been marked as deprecated.
When I first monitored the EDACS system about 10 years ago, there were three dispatch positions and two service positions. "Service", "Inquiry", "Records" and other channel names are often used interchangeably in law enforcement to refer to a dispatcher whose job it is to run drivers license checks, call towing companies and assist on-scene officers with other non-urgent requests. Since OPD was pretty short staffed the years I monitored, everyone calling service would request a place in line, and they would be called back by the dispatcher one at a time. For example, "1A26 can I get on the list?" "904 1A26 on the list." That list seemed awfully long at times!
Originally the patrol channels were broken up as follows:
Patrol 1 - West Dispatch (West Oakland to Lake Merritt)
Patrol 2 - Central Dispatch (Lake Merritt to around High St, Fruitvale area etc)
Patrol 3 - East Dispatch (East Oakland)
Patrol 4 - Car-to-Car
Patrol 5 - Car-to-Car
That system persisted on the Oakland P25 system for a while, and I think west took patrol areas 1 through 3 and east took areas 4 and 5 (on the OPD beat map).
I haven't lived in the area for quite a while so I can't verify what talkgroups are currently being used for what on EBRCS. I hear they might have moved back to option 1 (which made a heck of a lot more sense to have dispatchers on 1 thru 3 and freed Patrol 4 and 5 both up as car-to-car channels), but they may still be stuck on option 2. Radiobern could tell us for sure.
As a previous poster also said, there should be Tac 1 through Tac 15 waiting to be found on EBRCS.

I empathize with Stingray327, trying to program OPD is not that easy for the novice user. I've been trying for about a day now and it still eludes me. I have a HomePatrol 2 and a BCD536HP. I've tried the Sentinel for the HP2 and I see the EBRCS, Oakland with the Patrol 1 - 5, etc. I've programmed those into my HP2 and occasionally I hear some radio traffic, but not what I expect from such a busy city. I go to Live Audio on the Radiorefence.com site and I hear much more radio traffic from OPD, so I know I've not done this correctly.
And, according to my Sentinel Favorites List I also see the ALCO NW Simulcast Site with radio frequencies in the 7xxxxxx. ranges. According to the previous posts on this thread, I think this is where the OPD radio traffic will be found. But, somehow, those aren't getting copied into my HP2. I've been on Youtube and watched the instruction clips on how to set up Favorites.
So, I hope someone would post a few simple instructions for the novice user on how to program OPD into a HP2. I've not yet tackled the BCD536HP, but may move onto that today.
What I did was lock out Contra Costa Co since Alameda Co. and Contra Costa Co. are both on EBRCS and lock out the Contra Costa Co. groups and left the Alameda Co. groups in. Maybe someone here could explain this more in depth and detail for us in simple terms easier to understand? Hope this helps.
I live in Richmond and I pick up OPD Patrol 3 just fine using my HP2 with the tiny stock antenna. From my location I can receive BPD, UCPD, and EMERYVILLE PD as well. I think Patrol 3 is East Oakland because I heard a call being dispatched to Fruitvale so I thought I would be able to hear the West Oakland channel. I don't think the ALCO NW Site is in the HP2, but could be wrong. I tried to manually search for that on the HP2, but maybe it is not visible that way.
My BCD536HP has better reception and I'm working on programming that one right now.
