" summary

A $30 USB SDR dongle plus open-source decoders yields concrete outcomes: 50 experiments in a week, including decoded NOAA weather-satellite images (first attempt noisy, second usable), measuring Doppler shift to estimate satellite speed ~9 km/s, receiving a weather-balloon telemetry stream and riding trains to its predicted landing (balloon not recovered), FM/shortwave reception from overseas stations, and using an NFC library-book tag to send Morse between phones — the NFC trick actually works.
