The Soviets (and most of their Eastern bloc allies) utilised two different types of jamming transmitter. Skywave jamming covered a big place but for The explanations explained was of limited effectiveness. Groundwave jamming was more effective but only in excess of a little space and was thus utilized only in/around big metropolitan areas all over the Jap Bloc. Both kinds of jamming have been a lot less helpful on higher shortwave frequencies (higher than fifteen MHz); nevertheless, quite a few radios bought over the domestic market within the Soviet Union didn't tune these larger bands.[13] Skywave jamming was generally accompanied by morse signals as a way to permit (coded) signal jammers identification on the jamming station as a way that Soviet checking posts could evaluate the success of every station.
