Majority of the communication equipment of an average and higher power was imported from Soviet Union, Poland and Hungary. In some cases, they used the types produced by Soviet licence. It was namely the case of the radio stations of ASTRA series, i.e. R-105 type and its successors R-108 and R-109. R-105 radio station was developed in Minsk on the basis of timeless German war-time radio station of Torn.Fu.g. Type. German designers of Telefunken and Lorenz corporation, displaced to U.S-S.R. at the end of WWII, played an important role at its development.
