Would anybody be able to determine why I'm seeing such high offset and
jitter times from my GPS 18 LVC? As well as, why its now listing as
a fasltick? Below is my ntpq output along with my server/fudge configs
and syslog outputs. I also threw in some (gpspipe -r) data below.
Thanks to anybody that can help me get this Stratum 1 server tweaked.

xGPS_NMEA(0) .GPS. 0 l 67 16 360 0.000 -844.13

xSHM(0) .PPS. 0 l 3 16 377 0.000 -852.96

A value -0.844 etc. suggests that you might be synching on the wrong edge
of the PPS signal. What OS? Is it a GPS 18 LVC or a GPS 18x LVC? there
are firmware issues with the 18x.
Why the type 28 driver? I use just type 20 on my FreeBSD system:
