    I have built a new precise OCXO clock reference for QO100 according to the open source development by DJ0ABR, for the portable station in my caravan.

    It takes the clock from a 100MHz OCXO and divides it into 50 MHz for my Pluto and 25 MHz for the LNB reference.

    I have connected a GPS, but in general this is not really required since the frequency is already very stable with the OCXO only, at least after a few days of operation, after the run-in phase of the OCXO.

    Additionally I am experimenting with a mixer designed by IU8CRI to receive QO100 not only with Pluto but also with my Yeasu TRX.

    The description of the clock reference is here:
