As we used to say in racing, "Speed costs money. How fast do you want to go?"
CRDs are not particularly expensive, especially when you consider the
performance and what it would take to achieve that performance with
other solutions -- assuming you need/want that performance (and what
kind of time nut would you be if you didn't?).
However, I'm not convinced that a cheap (or even free) 26 MHz
oscillator plus a downconverter will be less expensive for a given
level of performance than just buying a decent 10 MHz OCXO in the
first place -- I've bought quite a few very nice ones on-line in the
$20-50 range. Mark Sims has suggested some as well (check the list archives).
Best regards,
Charles
