[time-nuts] KS problem

Hi Charles,
These hiccoughs match the ones I was getting comparing the KS to my homegrown GSPDO, so I don't think there's any chance it's the PRS45A.  I was wondering if it might be the antenna.  My homegrown unit uses the same antenna via a GPS Source MS-14 splitter, but the LEA-6T in my homegrown is probably a better receiver than the UT+.  I'll have to pull the splitter out of the circuit to see if the KS doesn't like it.  Maybe I'll just try a different port first, as that's easier.

Assuming the hiccoughs were the KS and not the PRS, it looks to me 
like you recorded two periods where the KS lost tracking.  Did you 
have a good, outdoor antenna with clear view of the whole sky?
