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

[Skip Withrow]

There is a crystal in the sa.22 that will determin what output frequencies
are available for output.  On the 9.8MHz and 10MHz versions it is 6X the
nominal output frequency (58.x MHz vs 60MHz).  The sa.22 can be programmed
to output xtal freq/2N for n up 2^16 (IIRC, it's in the manual).

Thus, you can change 15MHz units (found on telecom boards) to 10MHz (n is
changed from 2 to 3).  I have done this.  But, you can't change 9.8MHz
(found on different telecom cards) units to 10MHz.
