[amsat-bb] Fox high speed?

A few days ago the satellite switched from DUV to HS shortly before my 
LOS.  The program was set to "auto" and I was able to decode and 
uploaded my first six frames of HS data.  Using V:1.03-h, the s/w  
worked as expected..

Hi Ed,

That is what HS looks like.  There have been 2-3 other periods of HS 
telemetry over the past few days.
In the ones I saw or heard, my software did not automatically switch, 
and when manually switched
copied nothing.  There are known issues with HS in my station which I am 
working on, so that is not
entirely unexpected.  I was able to copy a few blocks on a much earlier 
test.  From other comments,
you do need a stronger signal than DUV, and depending on your equipment, 
a higher sampling rate.
