Because radio propagation on shortwave is usually tricky to forecast reliably, listeners from time to time uncovered that there have been times/moments if the jamming was significantly ineffective because radio fading (because of atmospheric conditions) was affecting the jamming signals but favouring the broadcasts (a phenomenon in some cases dubbed "twilight immunity"). On other times certainly the reverse was the situation. There were also times when jamming transmitters ended up (quickly) off air because of breakdowns or upkeep.
