Rövid tartalmi összefoglaló angol nyelven
The year had brought several incidents that could have motivated Tomcsányi’s suicide. Imre Geiger, the managing director, had been condemned to death in the Standard trial on February 21, while Zoltán Radó and several other engineers had received prison sentences of 13-15 years. On July 18, the international court in the Hague dismissed the Western powers’ charges of religious persecution by Hungary, Romania and Bulgaria. April 4 (Liberation Day) and November 7 (the October Revolution) were declared to be national holidays. Most conscientious members of the generation of engineers bom at the beginning of this century went through similar troubles. Some emigrated, some were imprisoned, some were exiled to the provinces, some were placed in demeaning situations, and some yielded their places to ‘cadres’, some trained and some not. History had dismissed the first generation of Hungarian broadcasting engineers by the end of 1950. Those who stepped into their shoes had different ideas and a different sense of mission. Dr László Falus: The decades of the transmission industry The almost seven-decade history of the transmission-engineering industry is worth examining in terms of the various types of transmitter. Production began in the 1930s. Three years after the 28 kW transmitter at Lakihegy had started up in 1928, the Hungarian Post invited tenders to deliver further transmitters. The winning tender came from a Hungarian factory, Standard Electric. Standard built the 120 kW medium-wave transmitter at Lakihegy and four lower-strength provincial relay stations. The main transmission station, completed in 1933, was the pride of Hungarian radio broadcasting, as one of the strongest transmitters in Europe. In the following decades came the manufacture of smaller transmitters, and after the Second World War, rebuilding of the transmitter network that had been destroyed. The first main, 135 kW medium-wave transmitters were erected at Lakihegy and Szolnok in 1948-9. A second, high-performance short-wave station was completed at Diósd in 1949, with two 100 kW transmitters and a large antenna system. A third large transmitter went up at Balatonszabadi, as did several other provincial stations. The next large transmitter to meet international requirements was the 300 kW installation at Lakihegy in 1968. The big assignment in the early 1970s was to develop and make the equipment and antennae for the new short-wave transmission station at Jászberény. The two 250 kW transmitters and the 16-piece remote-controlled antenna system were completed in 1974. VHF transmissions began in the second half of the 1950s and developed strongly in the 1970s, when the transmitters, integrators and antenna systems for a three-programme OIRT-band system were installed. Several generations of transmitter equipment were made over the decades, the development being apparent mainly in the degree to which transistors were used, in automation and in quality parameters. Most of the network was installed with 10 kW and 3 kW equipment. In the final stage of building the network and as the earlier transmitters became due for replacement, a new generation of equipment was produced in the 1980s. This resulted in a range of fully semiconductor 1 kW transmitters. The objective remained of producing high259
