Stationary jammers are more expensive and powerful. They usually have a larger jamming radius and wider frequency band. Strong jammers can require additional cooling as they can overheat. Stationary jammers usually have a range of 100 meters and require a power supply of 230 V. Self-made jammers are low-power devices that work over short ranges ...
Radio jamming in China is a form of censorship in the People's Republic of China that involves deliberate attempts by state or Communist Party organs to interfere with radio broadcasts. In most instances, radio jamming targets foreign broadcasters, including Voice of America (VOA), Radio Free Asia , the BBC World Service , Sound of Hope (SOH ...
A Chilean national was arrested in Texas after a burglary, during which he was able to interfere with arresting officers' communications by using a radio jamming device.. Ignacio Castillo ...

The R-330Zh Zhitel is a mobile truck-mounted electronic warfare jamming communication station, manufactured by NVP Protek and fielded by the Armed Forces of the Russian Federation (AFRF). [1]
Radio frequency jammers are devices that interfere with communications systems, usually by sending out competing radio signals to confuse nearby electronics. It is a decades-old technology that ...
Limiting unsecure radio communication concerning the jamming and its effectiveness is also important. The jammer could be listening, and if they know that a certain technique is effective, they could direct more jamming assets to employ this method. The most important method to counter radar jammers is operator training.
Once the target frequencies were identified, radio frequency jamming could easily be employed to degrade or completely disable communications. The Have Quick program was a response to this problem. Engineers recognized that newer aircraft radios already included all-channel frequency synthesizers along with keyboards and displays for data entry.
The ALQ-99 is an airborne integrated jamming system designed and manufactured by EDO Corporation. Receiver equipment and antennas are mounted in a fin-tip pod while jamming transmitters and exciter equipment are located in under-wing pods. The system is capable of intercepting, automatically processing and jamming received radio frequency ...
