comms/rtl-sdr 2.0.2p0 OpenBSD

DVB-T dongles based on the Realtek RTL2832U can be used as a cheap SDR (software defined radio), since the chip allows transferring the raw I/Q samples to the host, which is officially used for DAB/DAB+/FM demodulation.

RTL-SDR provides some tools to work with these devices:

rtl_eeprom: EEPROM programming tool rtl_fm: general purpose analogue demodulator (narrow band FM, wide band FM, AM and SSB) rtl_sdr: tunes the device and captures raw data to a file rtl_test: check the possible tuning range rtl_biast: turn the RTL-SDR.com bias tee or any GPIO ON and OFF rtl_power: simple FFT logger rtl_adsb: simple ADS-B decoder (aircraft tracking) rtl_tcp: provides a network server for remote access to an SDR
