Evaluated 7 approaches for multi-channel CB radio monitoring on
Raspberry Pi 400. Top candidates: RTLSDR-Airband (existing software,
quick setup) and custom C with librtlsdr + liquid-dsp (~950 LOC,
meets all requirements exactly). Ruled out SDRTrunk, SDRAngel,
GNU Radio, rtl_fm, and Go-based approaches.
