Hi Guys, Does anyone have a multi-day (at least 5 days) timelab file comparing the 1PPS from a GPSDO to a Cesium standard, with a run of the mill rooftop antenna using at least an HP 5370A quality TIC?  I'm running a 7 day test like this, and I'd like to have something to compare to.  If you have one, could you send me a copy off-list? thanks, Bob Stewart ---   bob at evoria dot net   ----------------------------------------------------------------- AE6RV.com GFS GPSDO list: groups.yahoo.com/neo/groups/GFS-GPSDOs/info
