I have a RTTY flow graph that you may find useful as a starting point.
It's transmit only (I was just using it to test the RTTY decoder on the
ICOM IC-7300 ham transceiver).

And a program to generate a baudot test file from a text file.

Check out the FSK : Digital section of
https://wiki.gnuradio.org/index.php/SignalProcessing Shows you how to set
up some variables you'll need. Freq modulator and quadrature demodulator
are important. So is filtering.

Hi,
I would like to build an FSK modulator/demodulator. I'm using file
sink/sources for the moment. I need to be able to specify the two
frequencies, baud rate and sample rate (ideally at runtime).
I started with the gr-tutorial for qpsk, hoping to replace the
modulation/demodulation with gfsk blo
