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
|
|
|
|
Asynchronous mode is NOT currently supported on OpenBSD; some programs
|
|
have been modified to force synchronous mode, the following are not yet
|
|
available:
|
|
|
|
rtl_adsb: simple ADS-B decoder (aircraft tracking)
|
|
rtl_tcp: provides a network server for remote access to an SDR
