I use the 10 mhz signal from a simple GPSDO for this application. I suspect that doppler shift would prevent you from consistenly getting the accuracy you are looking for from the carrier of WWVH at your location.

Due to technical "improvements", the 4.43361875 MHz colour subcarrier which is available on the analogue TV system here in New Zealand, is no longer referenced to a Rubidium standard, and can be about +,- 1Hz in error. I have a communications receiver, and have been thinking of using this with Lyssajous figures on an oscilloscope, with the receiver tuned to WWVH in Hawaii, but a GPS might be a possability, if there is satellite coverage here in Invercargill, southern NZ. Bearing in mind I don`t need extreme accuracy, what is my best option, please?.................................................Don. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
