Transmit or receive any radio signal from 30 MHz to 6000 MHz on USB power with HackRF.

HackRF is an open source hardware project to build a Software Defined Radio (SDR) peripheral.

SDR is the application of Digital Signal Processing to radio waveforms. It is similar to the software-based digital audio techniques that became popular a couple of decades ago. Just as a sound card in a computer digitizes audio waveforms, a software radio peripheral digitizes radio waveforms. It's like a very fast sound card with the speaker and microphone replaced by an antenna. A single software radio platform can be used to implement virtually any wireless technology (Bluetooth, ZigBee, cellular technologies, FM radio, etc.).

Digital audio capabilities in general purpose computers enabled a revolution in the sound and music industries with advances such as hard disk recording and MP3 file sharing. Today's computers are fast enough to process radio waveforms in similar ways, and the radio communications industry is going through the same sorts of changes. One critical advance is finally taking place now, and that is the availability of low cost tools enabling anyone to take part in the revolution.

Wide Operating Frequency Range

HackRF operates from 30 MHz to 6 GHz, a wider range than any SDR peripheral available today.  This range includes the frequencies used by most of the digital radio systems on Earth.  It can operate at even lower frequencies in the MF and HF bands when paired with the Ham It Up RF upconverter.

Transceiver

HackRF can be used to transmit or receive radio signals.  It operates in half-duplex mode: it can transmit or receive but can't do both at the same time.  However, full-duplex operation is possible if you use two HackRF devices.

Portable

You don't have to carry an external power supply with you when taking HackRF on the road because it is powered by USB.  It is small enough to fit easily into a typical laptop bag.  Your HackRF will be slightly smaller than the beta unit pictured above and will protected by a full enclosure.

HackRF is designed primarily for use with a USB-attached host computer, but it can also be used for stand-alone applications with Jared's HackRF PortaPack, an add-on that gives HackRF an LCD screen, directional buttons, and audio ports.

Low Cost

HackRF was designed to be the most widely useful SDR peripheral that can be manufactured at a low cost.  The estimated future retail price of HackRF is $300, but you can get one for even less by backing the Kickstarter project today.

Wideband

The maximum bandwidth of HackRF is 20 MHz, about 10 times the bandwidth of TV tuner dongles popular for SDR.  That means that HackRF could be used for high speed digital radio applications such as LTE or 802.11g.

Open Source

The most important goal of the HackRF project is to produce an open source design for a widely useful SDR peripheral.  All hardware designs and software source code are available under an open source license.  The hardware designs are produced in KiCad, an open source electronic design automation tool.  You can download the Jawbreaker (HackRF beta) design and build your own HackRF today!

How to kill UAVs ! La sécurité des drones en question

The UAVs have two alternative systems for communication.

Line of sight radio :
In the military C-Band  500 - 1000 MHz that can be jammed with simple spark-gap radio

Satellite communication :
In the Ku-Band between 10.95 - 14.5 GHz, and  the satellite can be jammed.
The Uplink-Band to the satellite is 13.75 - 14.5 GHz
The Downlink-Band from the satellite is 10.95 - 12.75 GHz
And you should jam the Uplink frequencies with a jammer directed at the satellite.

 As you can see in the specifications, the satellite link system uses the same civilian commercial technology as television broadcasting companies.

If you jam the communication, then the operator becomes blind and the UAV will fly around until it crashes or the fuel is gone. But you must kill both links of communication to kill any rescue.

There are a limited number of satellite channels available which means that the satellite link becomes a bottleneck. The satellite is therefore used as a backup and jammer-rescue channel and for single special operations from far away from the target, while C-band radio is used for multiple simultaneous operations from near the targets. Every military base have their own UAVs that must be operated through the C-band radio. C-band radio is also reported to be used for take off and landing. Which means that the C-band radio is your primary target. The C-band radio is also easier to jam.

Diplomatie helvétique interceptée en ondes-courtes

Des transmissions de la diplomatie helvétique ont été captées, ce soir, en ondes-courtes sur 7673 khz. Les modes utilisées étaient l'ALE (http://en.m.wikipedia.org/wiki/Automatic_link_establishment)en mode chiffré (AQC), et le MIL-STD 188-110A (http://en.m.wikipedia.org/wiki/MIL-STD-188).

Des machines à écrire comme technique de cyber-défense

Après les révélations de l'informaticien américain Edward Snowden, l'un
des services spéciaux russes a décidé d'acheter des machines à écrire
pour taper des documents secrets, écrit jeudi le quotidien russe
Izvestia. Le FSO, Service fédéral de protection, issu de l'ancien KGB, a
lancé un appel d'offre pour l'achat de 20 machines à écrire.

Cette décision a été prise «après les scandales de WikiLeaks, les
révélations de Snowden ainsi que les informations selon lesquelles le
Premier ministre Dmitri Medvedev avait été écouté lors d'un sommet du
G20 à Londres», explique au journal une source au sein du service.

«Il a été décidé d'utiliser davantage de documents papier», selon la
même source. Interrogé par l'AFP, le service de presse du FSO s'est
refusé à tout commentaire. Selon d'autres sources citées par le journal,
les services spéciaux ainsi que le ministère de la Défense utilisent
toujours des machines à écrire.

Utiliser les signaux WIFI pour voir à travers les murs

Des chercheurs du MIT et du Laboratoire d'Intelligence Artificielle ont
récemment développé une technologie qui permet de voir à travers les
murs. Le système baptisé Wi-Vi, repose sur un concept similaire à
l'imagerie radar ou sonar, à la différence qu'il utilise les signaux
Wi-Fi pour suivre le mouvement d'une personne.

Cette technologie permet donc d'avoir une sorte de vision à rayon X et à
faible coût pour l'utilisateur. Il part du principe que lorsqu'un signal
Wi-Fi est transmis à un mur, une partie pénètre à travers et se reflète
sur les personnes se trouvant dans la pièce. Ainsi, les scientifiques
ont mis au point un système composé de deux antennes de transmission et
d'un récepteur. Ces antennes émettent des signaux identiques dont l'une
émet en sens inverse de l'autre, créant ainsi des interférences qui vont
s'annuler. Au final, seuls les mouvements effectués derrière le mur sont
perceptibles.

Selon Dina Katabi, un professeur du MIT : « Si la personne se déplace
derrière le mur, tous les reflets des objets statiques sont annulés, et
la seule chose enregistrée par le dispositif est l'humain en mouvement
».  En utilisant un seul récepteur, le système suit les déplacements
d'une personne, offrant ainsi la possibilité de la localiser en fonction
du temps de rebondissement entre les signaux.
