[bug#28133] [PATCH] gnu: Add rtl-sdr.; and gnuradio

[Danny Milosavljevic <dannym@scratchpost.org>]

Hi Arun,

LGTM!  But are we sure about the new module?  I've used rtl-sdr in a professional non-HAM setting before.  I guess it's OK, though :)

Back then I put "volk" into (gnu packages engineering) and not into ham-radio.scm - we might want to revisit it?

Also, just in case you are working on it as well, I have work-in-progress for gnuradio (something fails so I didn't submit it yet).  It might save some effort in that case:
