I have just purchased a Thunderbolt GPS receiver. I hope to use this
to discipline an oscillator on 66.66666 MHz so I can use it as a LO on
my Software Defined Receiver (SDR-IQ).
Building such an oscillator is a little over my head so I thought I
would ask the group if anyone knows where I could buy the missing link
of this project. I have put a drawing of my project on the web showing
the specs of what I need. The oscillator is shown in the blue box.
Any help or suggestions would be greatly appreciated.

---------------
One option, although perhaps a bit bulky as it's a 3U 19inch rackmount
unit, would be to use something like a PTS160 synthesiser, or Wavetek 5120A
which is similar, which can be driven by an external 10MHz reference and can
provide outputs between 100KHz and 160MHz with resolution as fine as 0.1Hz
depending on number of incremental modules fitted.
