[time-nuts] WWVB remodulator seems to work fine on 3 V But

[Brian Alsop]

Reminds me of the FT-243 xtal controlled transmitter Novice days.  Xtals 
of the frequency you wanted were hard to come by.  We would grind xtals 
a bit on a bed of very fine abrasive to raise their frequency.

The other trick was taking a pencil and adding graphite to the xtal 
faces to lower it's frequency.  You couldn't add too much or it would 
stop oscillating-- forever.  Never did understand the forever part. 
Removing the graphite didn't bring it back to life.
