What do you mean by "totally different results"?  What were the readings or 
the differences?

Subject: [time-nuts] Different Survey Results

> Hello,
> I'm new to the list and to the themes at all. I'm running a V3 Thunderbolt 
> using the great Lady Heather Software (thanks for this).
> Setting up the tbold for the first time I made a 48h survey.
> To compare the results I also started a SirF III GPS using VisualGPS
> software and after the 48h period I got totally different results.
> Knowing my real geografic coordinates very well I saw that the tbold
> obviously calculated wrong data.
> So my questions to the group are:
> 1. For getting best disciplining results out of the tbold: Do I better
>    put in the coordinates manualy or using the survey function?
> 2. Is it necessary to modify DAC and temperature settings using
>    command line options (or using the heather) or does tbold work best 
> with
>    factory settings?
> 3. Is there any "How to.." pdf or book on the net which comes with more
>    informations about the tbold experiences than the well known
>    official pdf from 2003 ?
> Thank you very much for help.
