Re: [time-nuts] WWVB Dephaser Question

The additional article John sent us is a pretty good read. Having soldered all the little wires together with heat shrink, I can see the advantage of the epoxy approach. A consideration for the discussion. So far its been about the various tried and true methods for a RF frontend. But the real cha

A general comment on the use of Schmitt-trigger and counters on a conditioned analog signal: You will likely run into issues with missing counts or additional counts when the receiver experiences fadings or glitches (lightning, etc.) If this happens, the 60 kHz signal will jump in phase. Ole

For my little WWVB project  I used the table saw to cut off the upper 3 inches of a 5 gal bucket from Lowes (having removed the handle first). Then I wrapped that with about 30 turns of enameled wire from an old TV flyback transformer.  I then measured the inductance and added the required capa
