I thought FCC required all 700Mhz systems must be demonstrated Phase-II TDMA 6.25kHz spacing after January 1, 2017.

Maybe I misread the document but it says


Ventura County existing simulcast analog VHF system is currently at the mid-point of its
life expectancy. Ventura County has 28 allocated 700 MHz Phase 1 frequencies which
were approve by Region 5 California Public Radio Association to develop into our next
generation radio system. Ventura County hopes to bring along all City and government
users into a county-wide interoperable system. Funds will consist of capitol and grant
funding for each fiscal year of this plan.

That web page is out of date. On October 24, 2014 the FCC released a Report and Order (Proposed Amendments to the Service Rules Governing Public Safety Narrowband Operations in the 769-775/799-805 MHz Bands, et al., PS Docket 13-87, et al., Report and Order, 29 FCC Rcd 13283 (2014) (Report and Order) which eliminated the narrowbanding date for 700 MHz narrowband voice systems.

Any new TRS that will be implemented in Socal moving forward will be fully encrypted.

We knew this was coming down the pipe especially after PSEC went live.

Don't need a document to prove that encryption won't be implemented. It's a built in feature and any city or county that gets grant money from Dept of Homeland Security will flip the switch. Ventura County is no different than Orange County that flipped it 15 yrs ago, then Riverside County, and now San Bernardino is currently moving for full encryption.

Its a no brainer at this point.
