[time-nuts] Newbie looking for GPSDO kit or Project sites

[Luis Cupido]

Hi,

Depending how deep you want, to go you must
note that this one from ve2zaz (btw which is a great
design given it's simplicity) is a FLL not a PLL.
(unlike most of the others that really lock the phase of the
signal to the 10KHz or 1pps).
