    TX Link at Bakersfield to L.A. is down
    Last updated on June 20, 2021 by The C.A.R.L.A. Team | Permalink

    The link transmitter at 30 to L.A. is down. Audio coming North from L.A. can be heard but traffic going south from 30 cannot be heard in L.A. No ETA on repairs yet.

    Recent work at CARLA 4 & 29
    Last updated on June 1, 2021 by The C.A.R.L.A. Team | Permalink

    The RRFT concluded a 2 day trip to both CARLA 4 (Greenfield) and CARLA 29 (San Luis Obispo) this
    last weekend to take care of a number of needed things. Between the two sites we replaced some
    fans, made firmware updates, installed some new batteries, worked on an intermittent PL issue,
    replaced a bad tx link cable, re-tuned a couple of duplexers and a myriad of other tasks. We took
    care of the path fade issue between CARLA 4 and 29 and also troubleshot the bursts of white noise
    heard on 29’s inbound link channel from the north. We were unable to mitigate the intermittent
    white noise issue but have a plan to work on it on a future trip. It appears to be an on-channel
    mix from the trunking channels on site. As it was, we spent over 11 hours driving and 16 hours of
    work between the two sites and there was no more time or energy left to do more. We’ll send any
    updates as they become available.

    Network experiencing constant key-ups
    Last updated on March 28, 2021 by The C.A.R.L.A. Team | Permalink

    We are experiencing a scenario where the network is keying constantly with cycling key-ups after it
    gets hot from long conversations. We are trying to troubleshoot while this happens which may
    include taking systems off-link to isolate the problem. If it stops, DO NOT KEY UP as it will start
    the cycle over again. Sorry for the inconvenience.

    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.
