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 accuracy 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. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
