hanishkvc/prgs-sdr-kspecanal

a simple spectrum analyser which uses rtl-sdr dongle to scan the airwaves. It provides a zero span and full scan mode. Also supports masking out a previously saved siglvls. Done after forgetting fft theory ages back, so take it with a pinch of salt, but can still be better than nothing ;-) as relative is good enough many a times.
