HI Marcus, I see your point and also saw the schematic. The previous owner told me that this particular board was modified to have 10 MHz be brought out to the outside connector. I did verify it with the scope and indeed saw the 10 MHz coming out. I don't know if it's one of the standard factory options or just some custom modifications (the board has Olifantasia label on it). Will take a closer look at pins 3 and 1 of U103 as you suggest. If they are bridged indeed then I guess simple removal of GPSDO would do the trick.


That is NOT a factory-standard option.

    Dear Sailor Jerry,

    I'm not sure I'm following here: The 10 MHz connector is hardware-wise
    connected only to inputs, not to anything that can output anything;
    compare the schematic[1] on page 1. So, I'm pretty certain your device
    can't be condigured to have the 10 MHz connector be an output for
    anything.

    Can you maybe describe the problem you're having?

    Best regards,
    Marcus
