Re: LF: Re: GPS pulse timing

[Wolfgang Büscher <dl4yhf@freenet.de>]

Hi Stefan,

No significant improvement if the soundcard really supports 96 kHz 
sampling or more,
and if the standard deviation in the GPS-based pulses is already below 
100 ns.
That is displayed on the SR panel as 'StdDev60' (standard deviation in 
the recent 60 1-second pulses).
But it's a nice tool to compare the performance of different GPS 
receivers (and soundcards).
73,
 Wolf .
