This invention relates to a military radar- or radio communications system, in particular with mobile transmitting and receiving equipment, permitting a continuous change of a plurality of operating frequencies in accordance with a method of sudden frequency changes. In the periods when the transmitter is not required for the transmission of information signals, such as intervals in communication, the transmitter is used for jamming on those frequencies or frequency sub-bands which are not required for the transmission of information signals at that time. |
