In the meantime, some listeners in the Soviet Union and Eastern Bloc devised ingenious procedures (including home made directional loop antennas) to hear the Western stations with the sound. Since radio propagation on shortwave might be tough to predict reliably, listeners at times discovered that there were times/occasions once the jamming was especially ineffective mainly because radio fading (as a result of atmospheric disorders) was affecting the jamming signals but favouring the broadcasts (a phenomenon from time to time dubbed "twilight immunity"). On other times obviously the reverse was the case. There were also instances when jamming transmitters ended up (briefly) off air as a consequence of breakdowns or maintenance.
