For anyone who might be interested...Today's mailshot from Elektor magazine
features a low component count MSF receiver and display based on the Raspberry
Pi Pico board, and an even lower component count if a suitable antenna is
already available
That NIST news is from 2014; is your clock running a bit slow ;-) Still,

There are two short videos on that page. The first is only 5 minutes

Hi Erik,
Mathematically, no, a GPSDO cannot have a lower uncertainty (ADEV) than the
minimum observable uncertainty (ADEV) of the combined oscillator
(disciplined clock) and PPS (disciplining clock) from the GPS receiver.
Unless there is some magic trick to remove the uncertainty in a clock that
