    Hello Timm,

    Could you send the firmware me too.
    I have my up4dar down fron repeater site those days as I should add a remote reset and as in last time the tx modulation was very digitalized.

    Hello Bernd,

    many thanks for your quick reply.
    I put the same item yesterday in my eBay basket :-)

    I think is best solution and more reliablr, for sure I will buy 2 remote switch as my idea is to replace the old D-Star controller of my second repeater with an UP4DAR ... it works much better of any other modem in commerce, especially with weak and fading signals.

    Hello Denis,

    in last 4 month I get UP4DAR locked two time.
    The problem is that repeater works ine but network get locked, UP4DAR do not comunicate anymore and I havo way to reboot it by configurator.

    I need to drive to the repeater then is enough to reboot the board by softkey.
    There is a way to reboot it from RF via URCALL or could you take in mind that for further release ?

    Hello Denis,

    as you know I'm a fun of UP4DAR and I use it in my main repeater.
    In those days I'm playing with some professional instruments from R&S and I set deviation (from remote :-)) to get a perfect constellation, the RX deviation is fix around 1240Hz so I believe is fine too.
    By reading the manual I found that the "time shift" is displayed and should be less than 10ppm, but I'm not able to found it in the display or I did not understand something, could you please highlight to me into attached image ?

    Best Regards
