Meanwhile, some listeners while in the Soviet Union and Japanese Bloc devised ingenious methods (such as selfmade directional loop antennas) to listen to the Western stations throughout the sound. Because radio propagation on shortwave may be tough to predict reliably, listeners occasionally identified that there were times/moments if the jamming was notably ineffective for the reason that radio fading (resulting from atmospheric ailments) was affecting the jamming signals but favouring the broadcasts (a phenomenon from time to time dubbed "twilight immunity"). On other times of course the reverse was the case. There have been also instances when jamming transmitters were (quickly) off air as a result of breakdowns or maintenance.

Delicate jamming is jamming during which no sound is heard within the receiving equipment. The radio isn't going to receive incoming signals; nevertheless anything seems superficially standard for the operator. These are often specialized assaults on modern day equipment, including "squelch seize".

Jamming units could be recognized from the motion they accomplish on radio frequencies. Each time a radio frequency signal is transmitted in excess of a particular band, it is actually captured because of the antenna and amplified from the amplifier present in the jamming machine.
