    PSPS Event 10/11-10/12
    Last updated on October 10, 2021 by The C.A.R.L.A. Team | Permalink

    Due to high wind possibilities, PG&E PSPS (Public Safety Power Shutoff) events are planned
    for 23 counties in CA on Oct. 11th and Oct. 12th.

    Please listen for “On Battery” announcements from repeaters that are likely to be affected
    by these planned power outages and limit talk times to help preserve battery usage during this time.

    We have also created a one second “long tone” which will activate when CARLA is in
    power conservation mode due to multiple repeaters on battery backup.
    You’ll hear this tone when you unkey as a reminder to keep it short.


    CARLA 8 & 13 updates
    Last updated on August 29, 2021 by The C.A.R.L.A. Team | Permalink

    CARLA 8 is on generator power as of 11am Sunday 8/29/21.
    CARLA 13 was paid a visit by a RRFT team on Saturday to effect repairs on the hub transmitter, SB
    link antenna as well as fire mitigation around the property.

    Lake Shasta Before/After
    Last updated on August 28, 2021 by The C.A.R.L.A. Team | Permalink

    The Watts New articles usually cover whats working and whats not working on the Carla network and some
    related technical info. But we thought you might be interested in this article showing a Before and After of
    the water level at Lake Shasta in the North.

    These pictures were taken several years apart from the same general location. The first picture was taken
    several years ago. The second picture was taken in August 2021. The haze in the second picture is from
    several on-going fires in the State.

    CARLA 24, 18, 8 work
    Last updated on August 1, 2021 by The C.A.R.L.A. Team | Permalink

    -CARLA 24 is back on the air after repairs were effected to the TX VCO. We also found a bent link
    antenna that was likely hit from falling ice and that was replaced as well as a fan issue.

    -CARLA 18 required a visit to transition power from one generator to another as well as a couple of
    other modifications and updates needed to be performed on the Allstar IP link port. Power lines are
    still down in the area due to the Tamarack fire and we expect to remain on generator power for a
    few more weeks.

    -CARLA 8 had its link courtesy tone adjusted so it should respond like expected now when keying up
    with the link pl.

    BOTH CARLA 27 (Quincy, CA) and CARLA 18 (Topaz Lake, NV) are on stable generator back-up power
    now. We can lift the restricted mode we were in and thank everyone for their cooperation and
    understanding. Both sites were in the middle of their respective fire zones (Dixie and Tamarack
    fires) and both sites experienced some burn over on their respective mountain tops. We tried hard
    to keep both sites on the air by asking users to greatly limit transmit times to keep battery run
    time up in case the sites were needed for local comms. Fire crews worked hard to keep all the
    comm sites from burning for which we are very grateful.

    CARLA 30 in special operating mode
    Last updated on March 27, 2021 by The C.A.R.L.A. Team | Permalink

    CARLA 30 has been re-configured for a special mode of operation. The site is 100% solar and has a
    weakened battery string which may cause intermittent DC power outages. It may be a while before
    work can be done to mitigate the problem. Therefore, in an effort to reduce DC current consumption,
    we have re-configured the default operation mode of the repeater. It will normally remain off-link
    and in standalone mode only unless someone keys up the link PL. If the link PL is engaged, the
    repeater will connect to the link but disconnect after 30 seconds of inactivity from the repeater's
    input. This is regardless of ongoing link traffic in the background. CARLA 30's site is also a
    relay site for the path to/from CARLA 31 in SoCal. That will remain on-line unless power drops or
    we need to disconnect it.

    New CARLA & LVRA linking arrangement
    Last updated on January 6, 2021 by The C.A.R.L.A. Team | Permalink

    We’re pleased to announce a trial test run of a linking arrangement with a repeater system
    based in the greater Las Vegas area; Las Vegas Repeater Association (LVRA). They are a long
    time, established club that has been around for many years. https://www.hxo.radio/

    We plan to do this via an Allstar connection (which we currently use on a handful of CARLA
    repeaters internally, along with the RF links as back-ups).

    We have spent the last couple of months talking to each other on the phone, listening to each
    other’s networks and meeting via Zoom to make sure we are compatible with each other’s
    operation and were able to put a face to the names. Both groups feel confident and comfortable
    with the other and moving forward with a trial run.

    This will obviously expand coverage for both systems so please be cognizant of the fact that we
    are marrying two networks together which will take some getting used to. Be respectful of the
    fact that each time someone keys up, they are adding another handful of repeaters in Southern
    NV into the mix with our existing 30+ systems and visa versa. Please use good operating
    practices in general and don’t quick key, tailgate, rag-chew, tie up things for prolonged
    periods and leave plenty of breaks in-between as well as letting things cool down often. We
    realize there will be an up-tick in traffic with all the new callsigns and locations being
    heard out there and it will increase interest in more conversations which is great. Just be
    respectful to everyone and both systems and the amount of resources that will be tied up with
    each key-up and duration of your conversations and feel free to remind others of the same.

    LVRA has a couple of nets each week on their system but will disconnect prior to them as we
    don’t normally conduct nets on CARLA.

    Both group’s leadership teams have done a fair amount of due diligence in getting to know each
    other and making sure we are compatible with one another. We all agree this feels like a good
    fit and will be a good endeavor to pursue. Things should go into effect within a couple of

    Please extend your warmest welcome to any new contacts from the Las Vegas area that you may

    Interactive Map is impaired
    Last updated on January 6, 2021 by The C.A.R.L.A. Team | Permalink

    Due to some changes by Google and their Map site, the CARLA Interactive Map is not functioning as it should. We are
    working to resolve the problem but it has been a very slow process. Sorry for any inconvenience.
