[time-nuts] Lucent KS-24361 10 Mhz out success.

[paul swed]

On the output of the crystal oscillator you will want to buffer it and then
do whatever you like. Its a sine wave and as I recall of fair level several
volts. I did see a bit of distortion on the sine wave. It can be obtained
at J8 the unpopulated jack.
Now back to putting it in its case.
