[amsat-bb] ao 85 telem help

I am traveling, so have not had a chance to use live data.  PowerSDR
attenuates the audio significantly below 300 Hz, but is not a brick wall.
You can hear and see the PL tones on a local repeater.  During pre-launch
testing, I was able to play I/Q files through PowerSDR and get fair copy of
telemetry, but not anywhere as good as through a program which does not have
low pass filtering, such as SDR#.  Dave, W0DHB suggested switching to I/Q
from PowerSDR to FoxTelem which _should_ bypass the filtering.  I will get a
chance to test it in a few days.

I found the secret of getting audio from the monitor is to turn it on.  :)
The button label is backward to my thinking.  You will need to uncheck some
of the filtering boxes to get full voice audio.

My set up is flex 5000 virtual audio cables I get good eye pattern when
signal is not if a fade. But have not been able to decode telemetry.

I also have no audio out on the monitor.


Any suggestions?
