![]() The rtl_fm program is a command line tool that can initialize the RTL2832, tune to a given frequency, and output the received audio to a file or pipe the output to command line audio players such as the alsa aplay or the sox play commands. The rtl-sdr codebase contains a basic FM receiver program that operates from the command line. These command line tools use the library to test for the existence of RTL2832 devices and to perform basic data transfer functions to and from the device.īecause most of the RTL2832 devices are connected using USB, the librtlsdr library depends on the libusb library to communicate with the device.Īt the user level, there are several options for interacting with the hardware. This codebase contains both the library itself and also a number of command line tools such as rtl_test, rtl_sdr, rtl_tcp, and rtl_fm. Most of the user-level packages rely on the librtlsdr library which comes as part of the rtl-sdr codebase. Much software is available for the RTL2832. If you find a device that is not yet in the device list but should be supported, please send the VID/PID and additional info (used tuner, device name) to our mailing list. People over at reddit are collecting a list of other devices that are compatible.

Terratec NOXON DAB/DAB+ USB dongle (rev 1) The following devices are known to work fine with RTLSDR software: VID Realtek never released a chip marked as RTL2838 so far. Note: Many devices with EEPROM have 0x2838 as PID and RTL2838 as product name, but in fact all of them have an RTL2832U inside. Tunerĥ2 - 2200 MHz with a gap from 1100 MHz to 1250 MHz (varies)Ģ2 - 1100 MHz (FC0013B/C, FC0013G has a separate L-band input, which is unconnected on most sticks)ġ46 - 308 MHz and 438 - 924 MHz (gap in between) The frequency range is highly dependent of the used tuner, dongles that use the Elonics E4000 offer the widest possible range (see table below). A stable sample-rate of 3.2 MS/s without lost samples is only possible with the Etron EJ168/EJ188/EJ198 series of host controllers due to their specific maximum latency. The RTL2832U outputs 8-bit I/Q-samples, and the highest theoretically possible sample-rate is 3.2 MS/s, however, the highest sample-rate without lost samples that has been tested wit regular USB controllers so far is 2.4 MS/s. Antti Palosaari has not been involved in development of rtl-sdr. The possibility of this has been discovered by Eric Fry ( History and Discovery of RTLSDR). DVB-T dongles based on the Realtek RTL2832U can be used as a cheap SDR, since the chip allows transferring the raw I/Q samples to the host, which is officially used for DAB/DAB+/FM demodulation. ![]()
