hi all,
I'm using gnuradio companion to perform fsk modulation using CPFSK block .in that we don't have an option to set the carrier frequency.so can anyone please tell me how can we set the carrrier frequency.I'm not using USRP.Also how can we perform FSk demodulation in GRC
Thanks in advance

Anju,
If you aren't using a USRP, are you using any radio hardware system? If not, there's really no such thing as a "carrier frequency."
For FSK demodulation, I recommend starting with the GMSK mod/demod block (in gr-digital/python). You can use a similar technique for FSK with different filtering and parameters.
