this is where something smaller and lighter (RTL-SDR + rpi) would be preferable to larger and heavier :P

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.]
