    Default P25 on Amateur in Orange County, California

    I have looked a bit but I do not see any 2m or 440, P25 repeaters in Orange County.
    Does anyone have some updated information?

    I am bringing up a 900Mhz P25 in a few months, more information to follow after testing.
    I'll post frequencies after that.

    The 446.640 and 449.500 analog repeaters have P25 but you would have to contact the owners for NACs and see when they use P25. I'm told there is a P25 only repeater on 445.380 but I've never heard any traffic.

    Most of the P25 machines are in LA county up in the San Gabriels. I know a few on here were working on adding a few voting sites, but not sure where they stand with that.

    Maybe they'll chime in.

    The SPARC 446.6400 repeater will pass P25 traffic, ask on the air and someone should contact you with the NAC info (it is split). They do ask that P25 users limit use to after prime time hours (10PM) as that repeater is quite active. And to add to what LA_XTS said, the CCC repeater on Mt. Thom has excellent coverage in OC. Jim the repeater owner is a good guy, and just asks you listen in mixed mode as the analog side is private.

    There are a handful of UHF P25 machines on Santiago Peak. 448.040 has P25 and the owner is a good guy. I don't know of any on VHF.
    I've got 900 P25 gear - so please keep us posted on the progress of your build.

    Side note: I see a good number of MMDVM repeaters in and around Orange County logged onto Brandmeister servers for DMR (only, it seems). It would be great if they'd also check that P25 Enable box

    i have 2 P25 mix mode uhf repeaters one on oat and one on Mt Harvard

    they are connected to allstar and the rest of the system.

    if you go in P25 you come out P25 on that repeater only and analog thru the rest of the system, the courtesy beep is analog and the rest of the analog system comes thru analog

    oat is 446.800 PL 103.5 repeater rx nac 293 repeater tx nac aaa (best to run digital carrier squelch on you mobile / ht)

    Harvard is 446.100 PL 100.0 repeater rx (your transmit) nac 293 repeater tx nac aaa (best to run digital carrier squelch on you mobile / ht)

    on 900 oat has changed to p25 full time, and it simulcasts with a medium level site in the valley to get better coverage up the 5 to the 14 and seems to work works good (only been on the air for a week in this configuration and more testing needs to be done, and there is an intermittent receive at oat i am replacing one part (module at a time to resolve)

    oat 900 is also using a odd split in order to get a way from the input noise, as i add more 900 repeaters (both multicast and simulcast) they will all use a common input in order to allow them to voter when there is overlapping coverage.

    oat input 902.025 nac 293 out output is 927.5875 nac 293

    there will be more 900 added as time permits, and in the future the uhf may become p25 full time

    Just programmed Harvard and it seems to work great in the LA Harbor on a hand held. Thanks!
