Digital modes like PSK31 use an incredibly small amount of bandwidth for communication. I wrote an audio modulator for the AVR that generates the waveform. At the time I was also working on a DSS SSB modulator and succeeded in transmitting a very short distance with signally just from the digital output pin.
