Hi Miuel,

I notice your different systems are using different mode bits - it looks
like both units are processing $GPGGA, with one defaulting to 4800 baud
and the other explicitly using 4800 baud.

This should make no difference, but I noticed it.

http://support.ntp.org/bin/view/Support/TroubleshootingNTP#Section_9.4.
describes the tally codes ('o', '*', etc), and I wonder if it might
be that one machine is seeing the PPS signal and the other is not, or
perhaps NTP is only seeing the PPS signal on one machine.
