_______________________________________________MurrayMany thanks,I started with the gr-tutorial for qpsk, hoping to replace the modulation/demodulation with gfsk blocks, but I didn't get the result I was hoping for. I don't fully understand the gfsk module or how to change the frequencies after the modulation. I tried the fsk burst modem example, but it's not what I want. I would rather not use PDUs and I don't want to transmit in bursts.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 would really appreciate if someone could point me to a tutorial or example on this. These are the resources I have read so far:
