If you are thinking of using a VCXO then you are not thinking of building a high-end GPSDO. This means you can use cheaper parts all around. A $2 micro processor and you can use the ADC and DAC that is built into the micro controller. There was a schematic posted here some time ago. I got it and was able to build a GPSDO for under $8 total. The trick is to do everything with the uP. -- 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.
