SDR - Software Defined Radio

A software defined radio powered by GNU-Radio and Qt. Garage door signal hacking using RTL-SDR and TI Chronos watch. Students Ido Livneh and Gil Freidlin from Tel Aviv University have been experimenting with garage door opener signals using the TI Chronos watch and RTL-SDR dongle.

Their technique involves using the SDR along with HDSDR software to acquire and record the signal, which is then analyzed using Python based tools and encoded for loading onto the Chronos RF wristwatch. The project report is available as a 23 page PDF download. Installing and using HDSDR - g4zfqradio. Click "Start" or press F2.

Look at Read the mouseovers. Also keyboard shortcuts, see an HTM file link in the Start Menu, actually located in the program folder. The keys affecting tuning can be particularly useful. Look at all the Options. Make sure that the IQ Swap is set correctly. Winrad - GNU Radio + RTL2832 DVB-T USB stick = $20 ultra-cheap Software Defined Radio Source code: Also for Windows: HDSDR with Wine on Linux & Mac OS X: For discussion, head to new Google Group: This video features the same device used with Winrad/HDSDR/WRplus: Compatible devices should be: ezcap, Hama nano & Terratec NOXON (get the first two as it has a better tuner – the Elonics 4000, same as FUNcube Dongle, broadest frequency range: 64-1700 MHz).

BladeRF now supports SDR-Radio, and headless mode (FPGA auto-loading) We have added many new exciting features and improvements to bladeRF in the past couple of weeks.

bladeRF now supports SDR-Radio, and headless mode (FPGA auto-loading)

By upgrading to the latest FX3 image ( ) you can now store FPGA images on the SPI flash by running `bladeRF-cli -L hostedx40.rbf`. This will allow your bladeRF to read an FPGA image from flash and program the FPGA without the need of a host computer. Software Defined Radio.

J'ai finalement décidé d'utiliser un arduino en mode analyseur logique low cost avec la methode donnée par al1fch. J'ai ainsi pu comparer la différence entre une trame envoyée de la telco et une autre envoyée du spoofer. Résultat, seul le délais entre deux trames émise à la suite diffère. En modifiant la valeur de 4*H_TIME (=9,6ms), par les 23,8 ms observé sur les captures de la telco toutes mes prises (Home System / Liveez) réagissent cette fois-ci à tout les coups !

/* Envoi un bit de stop par RF */inline void send_footer(void) { SIG_LOW(); //delayMicroseconds(H_TIME*4); delay(23. A voir avec bidle si ça marche mieux avec ce correctif. D'autre part, concernant mes problèmes de porté de l'émetteur seeedstudio (pour rappel, j'avais du l'alimenter avec du 12V), j'ai suivi le conseil de barbudor : j'ai acheté les mêmes chez LedSeeIl faut mettre une antenne 17,3cm Maintenant, même avec le 5V de l'arduino mon émetteur fonctionne très bien.

Merci pour votre coup de main ! A Software Defined Radio in C# 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.

rtl-sdr – OsmoSDR

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 so far is 2.56 MS/s.

The frequency range is highly dependent of the used tuner, dongles that use the Elonics E4000 offer the widest possible range (see table below). Supported Hardware ¶ Note: Many devices with EEPROM have 0x2838 as PID and RTL2838 as product name, but in fact all of them have an RTL2832U inside. The following devices are known to work fine with RTLSDR software: This is the PCB of the ezcap-stick: More pictures can be found ​here. Usage ¶ Hardware. Users are asking, which receiver we would recommend.


The answer depends on many factors amongst application, environment, antenna and price. A radio that's out of this world! List of software-defined radios. BladeRF - USB 3.0 Software Defined Radio by Nuand. As wireless technologies become ubiquitous, Software Defined Radios (SDR) are gaining popularity.

Unlike most radios transceivers found in phones, WiFi devices, remote controls, etc. that can only communicate using specific wireless modulation schemes, Software Defined Radios are completely software based, which allows them to communicate with devices across the RF spectrum. Besides interacting with existing wireless devices, SDRs allow for the development of new wireless systems and protocols using intuitive software tools and APIs. bladeRF is a platform designed to enable a community of hobbyists, and professionals to explore and experiment with the multidisciplinary facets of RF communication.

A Software Defined Radio platform should not end at the hardware, which is why there is such a strong emphasis on documentation and tutorials. The bladeRF is a fully bus powered device that does not need to be plugged into an outlet for normal operation. HackRF, an open source SDR platform by Michael Ossmann.
