Got a chance to listen to the PSAT PSK beacon this morning on what was to be
the 1246Z pass.  I used HDSDR controlled by SATPC32 to get the passband.
HDSDR ot Digipan through a virtual audio cable to decode.  The Doppler was
off which makes sense with the Keps that are off from what was posted.  Saw
some initial short transmissions with gaps in between and then a rather long
run of transmissions.  I never saw any other PSK31 activity besides the data
beacon.  Someday soon I will give transmissions a shot.

Attached is a file with the data I decoded this morning.  Approximate time
stamp of first beacon is at the head of the file.  

I know you have made some reference in BB emails as to what some of the
parameters generally mean.  Will there be more details or a telemetry
decoder soon?

I love the PSK transponder idea the University has created and look forward
to giving it a try.
