SDR = software defined radio

Not sure how to organize this stuff, so I'll start putting notes for individual projects, and go from there.

Signal Decoding

Gnuradio/Wav to Waterfall - the first step to signal identification and decoding is being able to play back known signals in gnuradio from wav files. This is a basic flowchart that takes a wav file and runs it through a waterfall spectrum visualizer.

Gnuradio/Frequencies of Interest - the next step to signal identification and decoding is being able to narrow in on the interesting frequencies. This is a basic flowchart for narrowing in on a particular frequency for a particular signal.

Gnuradio/2015-08-17 - still working on trying to understand this satellite signal.

Gnuradio/2015-08-18 - think I got the baud rate of the satellite signal.
