[time-nuts] Cheap 9.8Mhz Sa.22c's

[Chris Albertson]

What are you planning to do with the 10MHz signal.   In some cases you can
simply use 9.8304MHz.  For example my plan to drive a DDS chip.  Nominally
the DDS wants 125MHz but iif I put in some odd-ball thing like 119.6MHZ all
that means is I have to change the binary word I load into the DDS chip.

In fact that could work.  Use the 9.8305 to drie a DDS then have the DDS
synthesize what you really want.  It will be as stable as the Rb. but as
accurate as 1/2 the step size of the DDS.
