For lucid insights into exotic weak signal data modes perhaps check fellow Kiwi Murray Greenman's esteemed site => www.qsl.net/zl1bpu/
Well for distances to a balloon of circa 250kM, even the humble RTL DVB TV dongle should be able to pick up FSK RTTY at 10mW.Just thought that another advantage of the $50SAT communications approach would the ability to receive data using low cost rf receivers, that do not normally support the SSB mode normally used by UKHAS flights. However, no reason why $50SAT communications technology would not be compatible with the existing international tracking network at a lower entry cost.
Not really, not enough voltage for long enough to power the transmitter, which takes around 85mA.Would a super capacitor have been able to 'fit' the requirement?
Works for me.The Dropbox link is broken
Excellent presentation.The presentation went well, there was a great deal of interest in our little PICAXE powered satellite.

Despite the fact that the battery and solar cells are seriously degraded, it just wont give up.
