[time-nuts] Trimble Resolution T versus Motorola Oncore UT+

The old Motorola Oncore UT+ is a good value.  They go for $15 on ebay
and have 50 nSec one sigma error on the PPS.

Both newer GPSes have better specs but I wonder if it matters if you
are building a Shera design GPSDO?

More important than all of this is the antenna location.  Make sure it
has a good view of the entire sky and is far from anything that can
reflect radio waves.   This pretty much means it is one  pipe mast of
some kind.
