    From Richard Menedetter@2:310/31 to All on Fri Feb 19 10:37:56 2016
    Hi All!

    Has anybody played around with the DRA818 modules?
    Available for 2m and 70cm.

    Propably available for much less on aliexpress or ebay.

    Those are 70cm or 2m (DRA818V) transceiver modules.

    Colleague is building a PCB with it.
    (Including a 72 MHz MCU, an ESP8266 WiFi module, and GPS and OLED capabilities)

    In the meantime I got myself this demoboard: https://odroid.ricsi.priv.at/sunrise.jpg

    Hmm, sounds interesting. :)

    Yepp ... it is ;)
    He has already the first PCB made.
    And it seems only one additional wire was needed (bug in his layout).

    But the MCU is very, very dumb at the moment.
    So much SW needs to be written ...

    Not a bad first effort. :)

    Usually the case until there's software! :)

    Have to check it out (again). :) Maybe when I'm on the road and accessing the BBS via NNTP (where I can click on links easily).

    At the moment he wrote a very minimal base system.
    Similar to AT commands. (at the moment freq and volume)

    Interesting thing to see is if he develops GPS/APRS functionality, before he gets bored with it ;)))

    We will see ...

    Cool,that's a good way to do it.

    Who knows. :). I was looking at building a mini IRLP node, perhaps with
    cross band repeat. I was looking at adding a local frequency or two and possibly cross band repeat.
