A fair amount of the RF-specific resources there are textbooks I don't have access to, though it's probably a transmission issue, honestly. However, the code consists a modified version of gr_sig_source_c (saved under an alternate name) and usrp_siggen.py, with hard-coded values for all wave properties save for the sampling frequency removed from usrp_siggen, and the new block assigning pseudo-random numbers to them within a range that should be tolerable. I'm not finding glaring problems, and it should be at least mostly working, but is not. Code here:
