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_sdr: tunes the device and captures raw data to a file rtl_test: check the possible tuning range Asynchronous mode is NOT currently supported on OpenBSD. rtl_sdr and rtl_test have been modified to force synchronous mode, and the following are not yet available: rtl_adsb: simple ADS-B decoder (aircraft tracking) rtl_fm: general purpose analogue demodulator (narrow band FM, wide band FM, AM and SSB) rtl_tcp: provides a network server for remote access to an SDR
