Hi Nuts, Most of you have probably seen this before, but I ran across a great 1975-vintage paper on how to synchronize your clocks and frequency standards to WWV's HF broadcasts. The equipment needs are very basic - a clock, a radio, and an oscilloscope. The procedure is simple and far more reliable than the tone-detection method I attempted earlier.
NBS Technical Note 668 - The Use of National Bureau of Standards High Frequency Broadcasts for Time and Frequency Calibrations ( http://tf.nist.gov/timefreq/general/pdf/453.pdf) Yes, I realize that GPS is literally a million times more accurate, but if all you need is milliseconds, this will do the job cheaper than a GPSDO or it could serve as a backup. Plus it's a lot of fun to stare at the traces. They are quite hypnotic.
