To address the one question Ref1s have no 10 Mhz. Just 15 MHz. I have reversed out the various paths but it seems so have others. Must have missed that thread. I do see the 5 to 10 doubler is in the q200-q203 region. I can't speak to the qualities of the signals and still have not found the magical X+Y= 15 Mhz. So what are folks doing that just have ref 1s? Is this the discussion on buffering the 5 Mhz and doubling? Regards Paul
