First thing to check with any GPSDO is the number of sat’s in view. If it does not typically run 
6 or more, the survey will take a long time.

> Hi,I have been trying out my True Position GPSDO, and I have a few questions. I have been running the survey for about 32 hours, and the figure of merit  goes between 2 and 4, usually 3 or 4, (range of 1-7). I have been monitoring the frequency adjusting voltage, and it varies between  2.1800 and 2.1900 v( 0-4v range). My unit has the Bliley oscillator.
