Hi Joe
Great, sounds like you should be all set. The 'source' command might not produce
any output (no news is good news in this case). You probably won't be able to do
much though without SDR hardware such as a USRP. However you should be able to run GRC
which enables you to create flowgraphs for simulation and analysis purposes... If you
have any disctap'ed receivers you could use them with OP25, (although you should not
expect LSM quality reception)
