Thanks Clayton, I didn't take it as demeaning at all. I was actually pleased to see others following the project. I am convinced there are avenues to HEO that may be affordable to us, but they probably won't be like any of our previous HEO sats. I saw lots of cool and exciting technology at the Satellite2014 show
in D.C. last week. I also think that a bunch of coordinated, linked LEO sats could give us the equivalent of a HEO at a fraction of the cost. I think the AMSAT board has been doing a great job in taking the steps required to reach such a goal by fostering cooperation with anyone that has a launch opportunity. I think the $50sat team proved that it doesn't take allot of money to launch a working satellite. Maybe of we had six people instead of three on the project we might have found a way to put a transponder on board... most innovation is evolutionary, not revolutionary and the only bad idea is the one you don't consider...

The satellite uses an RFM-22 transceiver and receives FSK, not AFSK, data signals. The packet must be formatted to the RFM-22 specification, it's not AX.25. All the required information for doing this is outlined in the $50sat communications document available from our dropbox account. The dropbox can be accessed through a link at www.50dollarsat.info. The MO-76 team will even award a Certificate of Technical Achievement to anyone that can confirm the two way QSO with the satellite. Hey, it's the best three guys working from their hamshacks can do in a 2" x 2" x 3" satellite.....at least until next time :)
