2.) Combating enemy transmitters (a) by jamming transmitters, (b) by means of measures on radios. (a), Combating interference transmitters. The English longwave transmitter Droitwich (200kHz, 1500 m) is effectively disrupted by a large German longwave broadcaster. In the near future, a strong longwave transmitter in the Protectorate will be used in addition to the interference, which will completely cover up the sometimes still audible English transmitter in most of the protetorate. On the 3 English medium waves, which spread propaganda, lies a number of European jamming transmitters, whose effect in the protectorate is not sufficient. Effectively disturbs the -English wave 8o4 kHz, 373,1 m in the whole of Bohemia and in a large part of Moravia the transmitter Prague-Straschnitz. waves 1050 kHz, 285.1 m and 1149 kHz, 261.1 m, which are of lesser importance, will soon be effectively disrupted by some small stations in Bohemia and Moravia and against Enda of the year by the radio stations in Iglau and Budweis under construction. b The disturbance of the English shortwaves is a difficult technical task, due to the large number of enemy transmitters sl and their transmission waves as well as the peculiar propagation conditions of the shortwave, which become audible only at a greater distance from the transmitter location with considerable volume. The Italian stations in the 49 and 41 m band have special significance for the Protectorate from the numerous European shortwave radio stations egeT, besides the stations of the Reich for the 49 m waves. The important waves at 25 and 31 m, on the other hand, are almost undisturbed. Therefore, since autumn 1941 in Prague and later auch in Brno numerous small jamming transmitters - local range were put into operation, which effectively disturb all enemy broadcasts on short wave within a radius of 8 - 10 km. (.eb This is the result of currently about 290 O00 radios in large-prague and large-brothers. For these purposes, 5o shortwave transmitters are being built in post workshops, which are also being installed in Moravian Ostrava and Pilsen. More than 350 000 radio equipment are being covered by this action.
