DMR on 800...

[kg6nlw]

Okay, this time I got a SOLID hit on a signal but it is giving a SITE 1 to it... @mlangeveld, maybe you can hear this?

2021/11/15 12:35:55 Freq=851.487500 Current site: 1
2021/11/15 12:36:03 Freq=851.487500 DCC=13 Found rest channel

The two LOCAL at the time, I was in Petaluma, references in the FCC database would be...WNWX384 (University of California) in Oakland or WPBH651 (UC Berkeley). There is a State of California license but that is in SoCal.

Regards,

I don't have any contacts at UCB, the guy I knew there retired a few years back.

But that frequency does belong the UC system. When UCB migrated over to EBRICS and shut down their old Motorola Type 2i system, those frequencies probably sat unused for a while. Likely they added the DMR repeater to support some non-critical campus operations that didn't require the cost of being on EBRICS.

WNWX384 is used for the mobiles/portables statewide.
WPBH650 is for the actual repeaters used at the UCB campus. Their license is still showing the old SmartNet system emission designators, though. No DMR yet.

Would be interesting to know if they have any other stuff on the other 4 channels:
851.9875
852.4875
852.9875
853.4875

Thanks for that. I'll have to log those into my search query. I think I was just lucky to catch that. I was scanning around the 800 band and came across the signal. It was just enough to pull those two lines I copied in my OP.

That matches up with what I saw. Interesting I could hear it from Petaluma...

If they are using the same transmit site as their old SmartNet system, which I think was on Sproul Hall, they have a really good view up and down the bay. It would make some sense reusing the site.
I used to be able to receive the old system from Mt. Hamilton down above San Jose really well.
