I hope so, as that's how we're planning to hook-up a Rubidium oscillator, using refclock_atom! Without kernel/hardpps, i.e. flag3=0. Note that we expect to have to alter the fudge regularly to track Rb aging. -- Ronan Flood <[EMAIL PROTECTED]> working for but not speaking for Network Services, University of London Computer Centre (which means: don't bother ULCC if I've said something you don't like) _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
