Frontier Silicon: Home of world-class digital multimedia solutions. RTL – Software Defined Radio. RTL2832U - SpenchWiki. From SpenchWiki Introduction This page details information specific to RTL2832U-based DVB-T USB dongles. The information applies to using it with GNU Radio (using gr-baz), and on Windows with the ExtIO plugin for HDSDR.
News I have created a new discussion forum on Google Groups as a place to discuss this code. Supported devices RTL2832U-based USB DVB-T adapters (non-exhaustive list, see here for how to install device driver on Windows). The following are the names of some common devices, but others not listed here will work if their USB ID is the same: OsmoSDR. OsmoSDR is a 100% Free Software based small form-factor inexpensive SDR (Software Defined Radio) project.
If you are familiar with existing SDR receivers, then OsmoSDR can be thought of something in between a FunCube Dongle (only 96kHz bandwidth) and a USRP (much more expensive). For a very cheap SDR (with limited dynamic range), you can use the DVB-T USB stick using the RTL2832U chip, as documented in rtl-sdr. It consists of a USB-attached Hardware, associated Firmware as well as GrOsmoSDR gnuradio integration on the PC. The first generation hardware (1.2 MS/s) was available to interested developers from We are currently doing a re-design for the second-generation hardware, featuring higher sample rate and other goodies. Christian has posted a detailed status update to the osmocom-sdr mailing list, describing his progress with enhancing the sample rate from 500 kS/s to 4 MS/s (at 14 bits ADC). Spring news in the GNSS and SDR domain. I have been following in the last few days interesting developments in the GNSS and SDR domain. 1. NV08C-CSM and dual constellation RAW measurements It's recent news that NVS has lifted the constraints on the firmware with RAW data for GPS and Glonass on L1.
In my opinion this is one of those rare times that the rules of the game are changed by one of its players. Essentially the NV08C-CSM provides real-time kinematic capability at 10Hz, with a price point as low as 35EUR/piece in small quantities. For once, the group of innovators is European. I had to buy one! The Realtek RTL2832U demodulator uses a 28.8MHz crystal by default.. which has too poor accuracy for a GPS receiver.. but a SDR acquisition algorithm can easily handle 100+kHz of apparent Doppler shift in the frequency search :) So for a nominal sky plot as the one below: And a signal looking like as follows: I could acquire the following birds: 3.
Stay tuned, GNSS is evolving rapidly! RTL-SDR compatibility list v.2 [work in progress, please help!] : RTLSDR. USRP Interfaces - SpenchWiki. From SpenchWiki If you are new to this... To jump straight in on windows: Download the self-contained installer Install (enable HDSDR to be automatically installed too - no separate download necessary) Launch HDSDR Select "ExtIO_USRP.dll" to be used as the ExtIO (this will attempt to automatically connect to a USRP via UHD) If you want to connect to another device (FUNcube Dongle, RTL2832-based USB DVB-T receiver), see Device Hint table below. For example: For RTL2832: add RTL to the Device Hint in the "Device control" window For FUNcube: add FCD, etc. Click "Create" to create your newly specified device Lastly, in the main window, click "Start" and you're off! You only have to do that once; for subsequent runs it'll auto-load everything.
News in brief Version 1.5.1 is available for download. Interfaces Although USRP is mentioned everywhere, you should read this as USRP+FCD+RTL2832 (since all those devices are supported through the same interface). Help Videos External resources. Rtl-sdr – OsmoSDR. 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. The possibility of this has been discovered by Eric Fry (History and Discovery of RTLSDR).
Antti Palosaari has not been involved in development of rtl-sdr. Specifications¶ 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. 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. Supported Hardware¶ People over at reddit are collecting a list of other devices that are compatible. This is the PCB of the ezcap-stick: More pictures can be found here. Software¶ Much software is available for the RTL2832.
