The receiver with the Goertzel algorithm is about 2/3 through.

What we call Goertzel mode on the P2 does not actually use Goertzel's algorithm. https://en.wikipedia.org/wiki/Goertzel_algorithm It's clever algorithm. It can also be used in reverse to efficiently generate a sine wave.

    Thanks, James. That is pretty neat. That's the kind of stuff we like to think about.
