Russ,

I see there is a TT560 reflock in the current codebase at 127.127.41.x .

I also see the TT560 is listed as an IRIG-B refclock card.

Did your setup work before and recently stop working?

3.5 is kinda old - http://support.ntp.org/Dev/ReleaseTimeline .

If you have the source code then debugging this shouldn't be too painful.
Even so, I'd be inclined to see if a more recent release worked better for
you.

Can you update this to the lastest version of ntpd?
