BULGARIA Petition. Sofia Vakaral history.
<https://www.facebook.com/save.vakarel/info> Historical and technical information on the Vakarel transmitter. Radio transmitter station "Vakarel" is located 2 kms from village Vakarel (Ihtiman) and is situated at an altitude of 900 m. The station was designed and built by the German company Telefunken specialists after long research to find the best place for broadcast in the ranges of long and medium waves. Very best features of the terrain and location ensuring RPS "Vakarel" to 01.01.2015 one of the leading country and Europe places in quality local and international broadcasting. On November 17, 1937 were carried out the first experimental broadcasts, and on 8 December the same year the official Launching and began regular operation of the station. With the start of broadcasts of Vakarel in Europe begin to clearly hear emissions Sofia Radio broadcast wave of 352.9 m / 850 kHz with power 100000 watt. The antenna of this transmitter type Blaw-Knox, is a real technical marvel, not only the time, but today. It has a diamond shape, high is about 200 meters tall and weighs about 130 tons, it is reinforced with four massive steel guyed. Of this type in Bulgaria has one antenna - Stara Zagora - also built in 1936, but the Hungarian company Standard. In Europe there are only two antennas - one in England and Hungary. Transmitter's contemporary, the technician Ivan Pickles tells about the construction of Vakarelska transmitter: "In 1936 year on a high hill near the village began construction Vakarel ... Facing the big spindle diversity antenna, 214 meters high, which ultimately rested on a glass insulator stick with four strong steel ropes. Dug deep ditch, which takes special high-frequency cable to the studio in Sofia. The construction of the transmitter is held by the company-builder "Telefunken", but in construction attended many of our workers, technicians and engineers, including Eng. Martulkov, Eng. Pipev, Eng. Kolarov." Ing. Stanislav Martulkov gives a detailed description of the facility in 1938 in year-on BIAD: "The location of the new transmitter is selected after basic research - about 905 m. Above sea level, 37 kms from Sofia, about 2.5 kilometers before Vakarel ... alarm antenna for airplanes going through the revolving lights of a thousand watts, with a red light, built 15 meters high masts on both sides of the antenna." Eng. Gregory Uzunov describes antenna Vakarel "powerful transmitter antenna near the village Vakarel built by "Hein-Lehmann" Berlin is an iron mast structure with fish shape (wider in the middle of its tapered at the ends) with a height of 179 meters. At the top of the antenna is extended by a metal rod, which rises in height and 17 meters in such a way that the entire height of 196 meters. (In other calculations height was 199.82 m). Conductor current serving four flange beams, power antenna becomes the bottom of tubular wire." Eng. K.Todorov: "From its center are tensioned steel cables (93 th meter), four in number, in 60 mm thick, composed of 121 wires. The base of the mast is concrete block, heavy 48 tons and blocks which are nailed ropes are 67 tons apiece." In the words of eyewitnesses lies only a hint of the colossal work on the construction of a high-quality national transmitter. Work laid with love and professionalism, sent waves of RPS "Vakarel 'homes even English. The transmitter of Vakarel is not affected by any natural disaster - did not hurt nor earthquake or hurricane winds. During World War II survived the bombing because it serves as a reference to the Anglo-American airmen. After 1944, the national transmitter end Vakarel came to be called "Transmitter Hristo Botev". Due to lack of spare parts, the transmitter works with half power - 50 kW. In 1950, the General Directorate for broadcasting contract with Hungarian company "Standard" for the repair of "Transmitter Hristo Botev". On February 24, 1954 the facility was put into regular ekspoatatsiya with renewed power of 100 kW. In 1984 vavveden in eksploatatatsiya Bulgarian transmitter development of the Institute of heavy radio electronics (led by the famous engineer. Hristo Bachvarov) with power of 40 kW, reset by means of long waves with a frequency of 261 kHz, a frequency known to thousands of Bulgarians and foreigners. The transmitter works until 2001, when after one month break is replaced by a Russian type DSV-75 with power 75 kW, which is currently unavailable. This transmitter was delivered to RPS "cape", but was never installed there. RPS "Vakarel" is one of the 26 remaining operating transmitters of long waves in the world. Broadcast programs can be heard here very well throughout the country and in Europe, have a loyal following. (6. Januar 2015) NO to the destruction of RPS "Vakarel", the symbol of Bulgarian Radio. Radio transmission station "Vakarel" - 78 year old pride of Bulgaria, was stopped on 01.01.2015. Help save her from destruction ! <https:\\www.facebook.com/save.vakarel/info?tab=page_info> <https:\\www.facebook.com/save.vakarel> <https://www.facebook.com/notes/836355213074915/> <https://www.facebook.com/save.vakarel/photos_stream?ref=page_internal> Dear compatriots, On 1 January 2015 contrary to the interests of thousands of listeners and national security were stopped long wave transmitter 261 kHz in RPS "Vakarel" and medium-wave frequencies in Gallikos Kilkis, Samuel, Kardzhali, Republic and Targovishte. Despite these many listeners medium-wave frequencies were largely local coverage predvatelyat in Vakarel had even internationally. Currently this site with historic and strategic importance is about to be liquidated following the fate of the majority of suspended radio in recent over 20 years. History of RPS "Vakarel" stretches back to back in 1934, when specialists from the company Telefunken visit Bulgaria in search of the most suitable location for broadcasting. After almost a year and demand measurements, they stop at the height above the Sofia village Vakarel. The location is ideal for a number of natural and geographical reasons. In fact it is the best in the country. In 1936 construction began on the first transmitter and in nearby 1937 already made the first tests. On 17 November 1937, the transmitter enters into operation. And from that moment began the creation of a legend, fought their way with her beautiful voice as hundreds of specialists, engineers and native genius of radiodeloto and millions of listeners. A national pride. Until this New Year's Eve, 78 long and turbulent years. The importance of the station is beyond doubt. Through its program of Bulgarian National Radio reach thousands of listeners outside other coating, whether or VHF television. Director General of BNR Mr. Radoslav Yankulov in a gust of inadequate and incompetent fatal modernism is going to war against the broadcasting of long and medium wave. According to his statements it is obsolete technology, rejected all over the world, too expensive for maintenance and generally meaningless. According to him, Bulgaria has 98% coverage of the country with the FM signal. He is even ready, in his words, a financial scheme by which to buy the poor listeners VHF radios. The truth, my dear compatriots, is much different. Bulgaria is a mountainous country and a considerable part of the population lives in the mountains. Despite the presence of several dozens of regional and national radio stations in VHF range, due to rough terrain their coverage of mountainous areas is very limited. These areas are served until recently by twenty regional and 7 national radio coverage of the SG and ST. These transmitters broadcast programs of Radio, plus news content was provided by the regional studios of Radio, giving listeners an interesting, diverse and relevant information for the region. Due to the nature of the spectrum reached their voice not only to the most remote corners of Bulgaria, but also to our compatriots abroad. Bulgarian speech was reaching tens of thousands from the western suburbs, the Bulgarians southern Romania, the thousands in Europe. According to experts in the industry to achieve too VHF coverage of 98% must be built between 800 and 1,000 new FM transmitter, most of them must be located in rugged terrain. Behind the promise of Mr. Yankulov hide millions of BGN deals for construction of road infrastructure, grid, microwave network and radio transmission network. And it will come to the Bulgarian taxpayer tens of times more expensive than the maintenance of all the destroyed and scrapped transmitters SG and ST will be the peak of stupidity and nekompetenstnostta, wastage of precious and needed resources. The cost would be astronomical. Then he is ready to gift VHF receivers of all poor listeners. If for example we put average supply wholesale price of about 30 lev for receiver and modest Suppose that in our country there are 100.000 people living in remote rural areas receive three million lev, the price of electricity for RPS "Vakarel" for 16 years. By what right Mr. Yankulov discriminates against those 100.000 Bulgarians in Bulgaria and thousands abroad? According to him, the whole civilized world refuses mass stops transmitters ST and SG. Therefore you in central Europe evening heard over 25 stations of the SG and 90 CB? For this reason you constantly modernize existing and build new facilities in the EU Member States? There are several reasons: 1) Huge coverage with lower costs The coverage area of a modern 100-kilowatt transmitter SG, suitably located and having a good quality antenna system is up to 2000 km. The annual cost of electricity would be about 127 546 lev. These are 17 cents per capita per year. The coverage area of this transmitter CB would be around 400 km. Costs 1000 VHF transmitter would be drastically higher. 2) high security communication channel The radio can not be easily stopped. This is extremely important in case of war, natural disasters and accidents. This is one of the main roles of the national radio - to reach all in such cases. In a statement Mr Yankulov expressed the view that it is best to listen to Radio on their mobile phones via the Internet. Due to its high complexity and multi-layered, his proposed transmission medium is the most vulnerable, insecure and chaotic. Radio is extremely safe, in case of disaster, accident or war, transfers can be organized by themselves transmitting stations protected studios, and from pre-recorded programs and others. 3) Extremely low cost and simplicity of terminal equipment National Radio is a public service. It must serve the people of them and for them. Although urbanization of Bulgarian cities, thousands of our fellow citizens live in isolated and remote areas where food is retrieved with a daily struggle with the ground for her gifts. Despite the proven return to rural life, most of these listeners are elderly and low-income. But almost all have a suitable receiver. In our country there are still thousands of fully operable tube and transistor radios. Despite the claims of Mr. Yankulov last repeated on 19.01.2015 in the morning of BNT1 that broadcasts CB of RPS "Vidin" of mediumwave 576 kHz reach all listeners in the country, this is not true. The transmitter is located in a very inappropriate place for broadcasting. Moreover purchased 400 kilowatt transmitter Thompson is poor and causes a number of problems in the operation, which requires to work with 200 kilowatts of power. Despite this power coverage area and signal quality are far from sufficient for the country. We are all aware of the financial, organizational and resource difficulties for the state national media. Abbreviation of regional programs is understandable. But the exclusion of only a transmitter having a capacity for national coverage is not. We appeal to all of you from the ordinary listener, to the members of the parliamentary committee on culture and media! Let us not allow mercantile tear everything built to destroy the little left of a once proud our national radio. Let us save RPS "Vakarel" and turn it into the main transmitter broadcasting center of Bulgaria. We call for: 1) Purchase of the State of RPS "Vakarel"; 2) Purchase and installation of a new transmitter SG from a reputable supplier (eg. Transradio, Gates or Nautel) with capacity of 50 kW in the estimated annual cost of electricity by 63 773 lev or 9 cents per capita per year; 3) Purchase and installation of new CB transmitter from a reputable supplier (eg. Transradio, Gates or Nautel) to power 100 kilowatts, at an estimated annual cost of electricity from 127,546 lev or 17 cents per capita per year; 4) preserving old Dvublokov transmitter DSV-75 as a reserve power, proven in the toughest conditions. 5) Construction of new diplexer that will allow simultaneous operation of two transmitters with existing antenna system; 6) Restoration of broadcasting program "Horizon" Radio station SG and ST for the country and abroad. 7) Construction of the area of one of the residential buildings in the station of a modern museum of Bulgarian radiodelo an information center and a library. The museum is open for organized visits of Bulgarian and foreign citizens, students from technical schools and universities. A good example of suitable transmitters are Nautel NX50 / NX100, Transradio TRAM50 / TRAM100, and Gates Flexdivia 3DX50 / 3DX100. These actions would provide not only 100% coverage for much less money than those needed to build a grand network of VHF transmitters, but also a safe, inexpensive and proven method to reach foreign audiences from countries like Ukraine, Turkey, Egypt, Italy, Austria, Czech Republic, Germany, Serbia, Albania, Belarus and others. All this can be achieved with the vote of confidence of German experts, chosen height of the village Vakarel as the best option for broadcasting in the country, with the vote of confidence of the Bulgarian State again be the master and guardian of a legendary station. Only in this way Bulgaria's voice can be heard again from all its podannitsi home and away. <http://l.facebook.com/l.php?u=http%3A%2F%2Fwww.peticiq.com%2Fsavevakarel&h=cAQFjshBT> _ Hard-Core-DX mailing list Hard-Core-DX@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/hard-core-dx http://www.hard-core-dx.com/ _______________________________________________ THE INFORMATION IN THIS ARTICLE IS FREE.
