That Happy Moment When

the demodulator you’ve been working on starts outputting meaningful data instead of gibberish (T7RPUR WIDE1 WIDE2 are valid packet radio strings).

I’m writing the demodulator in C++ and it uses the Goertzel algorithm.  Need to continue to flesh out the framer, and hook up STDIN to accept sound from rtl_fm and my new SDR dongle.

The goal: automated reception of Space Station packet radio, powered by Raspberry Pi.
