All the Zodiac messages use scaled integers for their values.  Lots of places for limited precision and round-off to sneak in...

When the survey completes, it goes to position hold mode.  The survey data area turns grey and shows the values the survey used as a reminder of how it got the position.  On a GPSDO with a configurable PLL,  the survey data area reverts to showing the PLL settings.

Thanks, yes probably better if one wants a precise elevation, although a rounded isn't going to make a hill of beans then add the elevation mask through the serial port using the binary word statements.

I see the Jupiter-T has a one satellite mode. For a user such as myself who suffers from a ground level north view on the 49th parallel would this option give me better precision when it comes to frequency.

Maybe a little bug in LH 5.0. Using the Jupiter-T receiver. Go to [S] for the Survey options. Select [N] for 3D Navigation mode and it brings up the heather.cfg file in the text editor. Not sure if the Jupiter-T actually has a 3D Navigation mode, but think the wrong shortcut key is being assigned?.
