I have not seen a whole PSK31 modem implemented. Looks like there is a decoder here: https://github.com/bitglue/gr-psk31
and here: http://sdradventure.wordpress.com/2011/10/15/gnuradio-psk31-decoder-part-1/ I experimented with an encoder here: https://www.youtube.com/watch?v=7IzxZKL2uUE It would be allot more work writing the GUI front end than the actual GR portion of the modem; probably why it has not been done.
