10 kW Jammer on Shortwave

PKI 6640Print

Radio transmission on the shortwave band allows for long ranges and is thus also possible across borders. Whether voice or data communication, jamming these transmission paths with the usual jammers is only feasible for limited areas. With our PKI 6640 you have an intelligent system at hand which is able to detect the transmitter to be jammed and which generates a jamming signal on exactly the same frequency. This is as well possible for further individual frequencies. Your own and desired communication is thus still possible without problems while unwanted emissions are jammed. A user-friendly software assumes the entire control of the jammer. From analysis of the frequency range via useful signal analysis, the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way. Different jamming modes: Random noise, tone, sweep, binary FSK, etc. are freely selectable or are used according to the system analysis. This way, communication channels, such as propaganda broadcasts, are perfectly suppressed.
