Watch the thread on this list about the Arduino based GPSDO. I think
you can get the price down to $50. If all you need is something to
calibrate frequency counter then all you need is 9 to 10 digit
I'm going to do this just to prove it can be done for a low two figure
price. But first I have to find a decent crystal oscillator that does
not use up 1/2 of my $40 budget.
If you want ultimate precision that you need a good GPS antenna in a
good location, A high-end timing mode GPS receiver and a high-end
double oven quartz oscillator. The cost adds up. But I think if you
relax the specifications and shoot only for 9 to 10 digits you can
greatly reduce the price.
