Hi David and BB,

We hope to release a development version of the BPSK/CW decoding software 
next week. We don't have the schedule specifics of the 12 April 
transmissions yet. These will be posted on the AMSAT and ARISSat1 web sites 
when available.

The transmissions on the 12th will see ARISSat-1 in low power mode, this 
means 40-60 secs on, 2 minutes off.
It should be a challenge to find and tune the CW signal then decode some 
BPSK data during the short on times. This mode was developed to be used when 
the batteries are low or the satellite is in eclipse. We will be collecting 
data and information to improve the BPSK demodulating, decoding and display 
software.  FUNcube Dongle users are encouraged to capture and record the 
downlink signals, then send us the files for examination. More information 
on where to send the files next week.

Additional information should be available later next week on the AMSAT and 
ARISSat1 web sites as well as the AMSAT BB.

Gould, WA4SXM
