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.
