The Soviets (and many of their Jap bloc allies) employed two forms of jamming transmitter. Skywave jamming protected a considerable space but for The explanations described was of confined efficiency. Groundwave jamming was more effective but only about a little space and was Consequently used only in/around major cities through the Eastern Bloc. Both of those sorts of jamming were significantly less efficient on greater shortwave frequencies (earlier mentioned 15 MHz); on the other hand, lots of radios sold around the domestic market place during the Soviet Union didn't tune these greater bands.[thirteen] Skywave jamming was usually accompanied by morse signals as a way to permit (coded) identification on the jamming station in order that Soviet monitoring posts could evaluate the performance of each and every station.
