this can be done very simplistically in an almost grab-and-go way,
even including i/q logs because an rtlsdr uses only 8bit samples and
has a smaller sample rate.  software already exists. [uhhh i patched
rtlsdr some time ago to store i/q logs with timing information, which
can be run with an existing wideband scanner like rtl_power or the
alternative cli one that uses soapy-sdr.]

[for bigger equipment, the first solution to the
bandwidth-to-storage-media issue should simply be downsampling, lossy
compression, and/or intermittent recording.  this moves priority
towards getting things running and working, rather than obsessing over
perfection.]
