[time-nuts] HP-106 and Sulzer Quartz Crystals

[Bob Camp]

Hi

The  interesting thing about cross correlation sources is that they don't need to be tuned. A fixed frequency device works just as well as one that's at exactly this or that frequency. There are a number of issues that creep into an OCXO based on the need to tune it. Simply put - the more stuff in the circuit the less likely it is to be quiet and stable. A source designed solely as a cross correlation reference *might* well do significantly better than a tuned OCXO.
