Hi

I’m a student and I’m really interested in understanding the FSK  
demodulation/modulation  
software techniques with GNURADIO and the USRP.  
I have a USRP with TVRX board and a DBSRX board. I’m very newbieto this  
SDR  
world. So I was wondering if somebody could share code (python or/and  
C++)  
so I can experiment and learn with my USRP boards. Also very interested  
in  
carrier tracker function on a fsk demodulator in case multiple carries  
are  
presents.  
I have a radio source of fsk so I guess I could start by receiving fsk  
with  
my USRP and then move on to the Tx side of the fsk.

Thank you in advance.

## David

Hi david 👋, Im having the same goal trying to get into the world of sdr  
( in college) so I set a target:  
Create fully functional wireless FSK immediate message system with 2 usrp’s (using gnuradio). Have you finished your project? If so can you help me? Thanks
