Meanwhile, some listeners during the Soviet Union and Japanese Bloc devised ingenious methods (including home made directional loop antennas) to hear the Western stations with the sounds. Simply because radio propagation on shortwave is usually challenging to predict reliably, listeners from time to time observed that there were times/times when the jamming was significantly ineffective because radio fading (resulting from atmospheric disorders) was affecting the jamming signals but favouring the broadcasts (a phenomenon from time to time dubbed "twilight immunity"). On other times needless to say the reverse was the case. There have been also instances when jamming transmitters were being (temporarily) off air because of breakdowns or servicing.

The external omni-directional antennas be certain that the signal is evenly dispersed throughout the place, providing complete coverage.
In occupied Europe the Nazis tried to jam broadcasts into the continent from the BBC together with other allied stations. Along with expanding transmitter power and incorporating extra frequencies, attempts were produced to counteract the jamming by dropping leaflets around cities instructing listeners to assemble a directional loop aerial that may help them to listen to the stations through the jamming. While in the Netherlands these aerials had been nicknamed "moffenzeef" (English: "kraut sieve").[9]
