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

[Danny Milosavljevic]

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:

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

Pushed, thanks!

IMHO, the modules in gnu/packages are quite a mess. There are many
modules with only one or a few packages (less than 10). At some point,
we'll have to revisit this, and figure out a better organization.

Debian has a category for HAM Radio packages. So, I thought it's ok to
create ham-radio.scm for rtl-sdr.

I'll look into it.

I think the module categorization doesn't really matter that much. And
each time we shuffle them around, it's a big pain for people maintaining
branches other than the master branch. So I'd prefer if we don't do a
big reorganization just for semantic reasons.

Actually, I don't think I can finish packaging gnuradio on my own. So,
if you open a bug report for it, perhaps we can co-author it.
