GNUradio works well on CentOS 7, but it is a bit of an adventure to get 
it built.  Marcus Leech's build-gnuradio.sh script works fine, and I've 
used it several times to build GNUradio on C7, both on x86_64 and on 
aarch64 (although I haven't performed that build on any of my ODROID C2s 
in some time and it really was a pain due to EPEL not being available 
for aarch64 at the time).  I tried the PyBOMBS build, but it wasn't 
successful for me, so I reverted to the build-gnuradio.sh script.

GNUradio supports a number of SDR dongles, including the RTL-SDR.

An old version of GNUradio used to be in EPEL, but it's no there as of 

For general-purpose SDR work GNUradio is fine, but if you need 
deterministic latency you may be disappointed.
