 First call for ARISSat-1 audio recordings

   If you haven't already heard about it, ARISSat-1 will be activated 
while still inside the International Space Station. The transmissions 
are scheduled to begin around Monday 11 April 2011 at 14:30 UTC 
and continue until 10:30 UTC on 13 April 2011. 

   The satellite will be running off of the battery, so the transmissions 
will be only 40-60 second long. There will be a delay of about two 
minutes between transmissions. That is, about 40-60 seconds ON, 
then about two minutes OFF (silence).

   If you are able to make an audio recording of the signals from 
ARISSat-1, I would be very interested in obtaining a copy of your
recording. I would be most interested in recordings of the CW and 
BPSK signals, but if are able to record the voice and SSTV signals 
I would be interested in those too.

   If you can make an SDR recordings ( I and Q ) with a Funcube 
dongle, FlexRadio, or SDR-IQ, record at the highest rate that your 
hardware and software supports. If you are making a regular audio 
recording, set the sampling rate to the "highest quality." If you can 
choose sample sizes, for example between 8-bit and 16-bit samples, 
choose the largest size.

   If you get any recordings with any of the signals from ARISSat, 
I would be very interested in obtaining a copy even if the recording 
is huge.

   Save your recordings as .WAV files.  Don't use MP3 format and 
don't convert the recordings into MP3 recordings. Leave the 
recordings as big huge .WAV files.

   If you successfully record ARISSat-1's signals, please contact me
for details on how to get the recording to me.
