Max, Thanks so much for your quick response. As it turns out, I'm already part of the op25 yahoo group, and I've seen the good work the op25 group has done. However, like you said, I am looking for an implementation that's entirely USRP based. I am only looking to be able to get the demodulat

[Discuss-gnuradio] FSK4 Demodulation on the FPGA

Hey all, Has anyone attempted to implement a C4FM demodulator on the Altera Cyclone in the USRP1? Right now I'm hoping to do this to read P25 encrypted packets on the FPGA instead of on the CPU, and I wanted to know if it was possible. If so, could anyone could point me to any sort of example
