Re: [time-nuts] Have 10 MHz need 19.2 MHz

Since the actual crystal frequency appears to be 19.2 MHz rather than
19.5, my original suggestion of injection locking it would have to be
modified. For example, you could divide the 10 MHz by 25 ( a single
74HC390 could do it) to make 400 kHz, so 19.2 MHz could sync to the
48th harmonic.
