Somehow I think I might be in sync with wrong edge of PPS.
Why?
That would put pps out, but I'd have guessed by only 100ms
if that's default.
Yes, David, according to the Technical Specifications the default is

A few us isn't bad from PPS unless I'm supposed to use the -350 ms

Note that the PPS via serial and parallel are both converging to

You're confusing me even more here! Is a summary:
1 - PPS connected to DCD (serial) - low offset
2 - PPS connected to DCD (serial) and NACK (parallel) - low offset
3 - GPS to serial, PPS to par

Next experiment is to try type 22 atom driver without type 20
nmea driver and have the three ntp servers for giving the
correct second. I'll try with parallel pps first since I was
unable to get this to work on desktop downstairs and it is
already wired up for that.
