Magnus, Here's a quick test you can do to decide if your problem is more on the OCXO side or more on the GPS side. Disconnect the GPS antenna and then see how the 10 MHz looks. You should see a 10 MHz that is as stable as any other 10811 you have. There should be warm-up drift, but no noticeable frequency jumps. /tvb _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
