AVR PSK31 on Flickr.
Encoding PSK31 with an 8-bit AVR doing analog waveform generation through a resistor ladder network. The phase-shift occurs after cosine-ramping down to DC, then back up on the new phase to reduce bandwidth. The FFT shows the primary spike at 500 Hz, the audio carrier frequency; I’m not sure why there is a second spike at 750 Hz. Source code.
