I'm using an older version of GNU Radio. I don't have the exact version number right now, but it's 2.x something. I'm using Ubuntu Linux 32-bit on a Core Duo Dell laptop. I don't know the name of the USRP daughter board I'm using, but it receives in the ~1GHz range that I'm working with and

Hi, I'm trying to demodulate and decode a CPFSK signal generated by a non-gnuradio source. I'm new to gnuradio and RF in general. I know that GMSK is a form of CPFSK, so I started by trying that, but I haven't had success. I noticed that the gmsk code is in the limbo directory, so I'm not sure
