Yo All! I have a provisional fix for issue #62:
https://gitlab.com/NTPsec/ntpsec/issues/62 In the NMEA refclock (#20), when PPS is lost, the peer jitter was left at the low value calculated for PPS. This jitter is then used for NMEA. So the NMEA time is wrongly thought to be PPS precise. This caused the selection algorithm to wrongly pick NMEA over other better sources. The fix is to reset the jitter for the refclock to default when PPS is lost. A try at a fix is in commit 7d49f80d If you are using the NMEA driver with PPS, please test. I'll also test.
