[time-nuts] Simple solution for disciplining OCXO with 1 PPS

[Dimitri.p]

Among Simple , analog, 1PPS
you'll have to pick two of the three.
The miller GPSDO needs 10KHz  it's simple and 
analog.  http://www.jrmiller.demon.co.uk/projects/ministd/frqstd0.htm

The IK0OTG is simple, uses 1PPS and is digital
