Having another go with the MRP40 decode software and replaying a recorded IQ wave file from yesterday I successfully decoded 80% of a full telemetry frame!
I also found this interesting pdf file detailing the construction of FITSAT-1 and discovered the 437MHz transmitter is only 100mW. So we have a flying metal cube measuring just 10cm x 10cm x 10cm travelling at approximately 4.5 miles/sec roughly 270 miles above the earth, transmitting with just a fifth of the power of one of those PMR446 hand held walkie talkies that in my experience struggle to maintain a contact over a few hundred meters! Isn't technology wonderful?
