[amsat-bb] AO-85 9k6 data

[Scott]

Do I recall correctly that in order to receive the higher data rate, a wider 
RF and/or audio bandwidth might be required?

I often have the audio bandwidth narrowed a bit (high end only) to better 
hear the voice traffic, which of course has no effect on the DUV as long as 
the low end of the audio filter is left at zero.  Ditto on the RF bandwidth 
if it makes the voices easier to copy on a given pass.

Steve,

9k6 data is not used very much on AO-85 since it is not required for any of 
the experiments, and its
use turns off the repeater.  It is turned on, rarely and briefly, for 
testing or other purposes.
There is usually an announcement on Twitter, Facebook and/or here in 
advance, though not always if
they are doing a quick look.  The Auto mode will pick it up, assuming 
everything else is working
correctly at your station.  It has been reported that the signal threshold 
to copy 9k6 is somewhat
higher than for DUV.

Expect to see much more when Fox-1Cliff and Fox-1D fly.
