Lebedev, USSR Academy of Sciences is working on the study of the physical properties of ferroelectrics and studying the processes occurring in semiconductors. Head of Laboratory "fief of the Academy of Sciences, Ben-Zion Moiseevich told the correspondent of the magazine:
— As you know, a number of substances known as ferroelectrics, with special electrical characteristics. For them, for example, typical long-term ability to maintain the polarization state after removal of the electric field. According to this property, somewhat reminiscent ferroelectrics, ferromagnetic materials (iron, nickel, cobalt) which, when removed from a magnetic field, retain magnetization state.
The special properties of ferroelectrics were discovered a few decades ago. They first found in Rochelle salt. The totality of electrical phenomena observed she and her similar materials, has been named ferroelectricity. In recent years there have been well studied and found many other materials. Among them, an important place of barium titanate.
The ferroelectric properties of barium titanate, opened in 1944 at our institution made it possible to apply this valuable material in a variety of technical fields. Piezoelectric ceramic barium titanate is used for example in pickups produced by our industry. To generate the ultrasonic vibrations in the equipment inspection are also used piezoelectric ceramic. This equipment is used on the railways for the detection of cracks in the rails.
The equipment is similar flaw, also used for the determination of the oxide layer in boiler plants. Capacitors with a dielectric of barium titanate having a strong dependence of the dielectric constant by temperature measuring devices are used as a temperature sensor, a piezoelectric ceramic of this material — as pressure sensors.
The non-linear capacitors, the so-called varactor developed at SRI MRTP as barium titanate dielectric is used with different additives. These additives significantly alter the properties of ferroelectric barium titanate: the capacity of the capacitor greatly depends on the electric field in the condenser.
The most important challenges facing our laboratory and determine the direction of its work in the future, along with the study of ferroelectrics are research in the field of semiconductors. Studies of motion of electrons in semiconductors and interaction of the electrons with the crystal lattice, and the study of the processes of recombination of electrons and holes will create a scientific basis for calculation and design of semiconductor devices.
An important application is also important to study the processes of impact ionization in semiconductors. Studies of these processes will create the theoretical basis for the construction of high-voltage semiconductor diodes.
Great achievements science in recent years to develop methods of converting radiant energy into electrical energy, largely due to the creation of new semiconductors. Currently, you can really have to talk about the development of practical methods of direct conversion of solar radiation into electrical energy.
The editors asked the professor, Doctor of Technical Sciences, Corresponding Member of the Ukrainian Academy of Sciences Alexander Alexandrovich Kharkevich tell the readers of the magazine «Radio», on what problems in communications work now Soviet scientists.
That’s what we told the AA Kharkevich: — We are currently witnessing the rapid development of communication technology, and more are on the eve of significant changes associated with the introduction of new techniques of scientific principles. Of all the vast scientific and technical issues in the area I would like to touch on a few areas, developed by the Moscow Electrotechnical Institute of Communications and laboratories wireline USSR.
First, a few words on television. It is known that the television signal has a very wide range — about 6 MHz. This eliminates the possibility of transferring it to a conventional wired and radio channels. The television broadcast in the UHF line of sight; for long-distance transmission requires either a coaxial cable or microwave links. It needs to be resolved the problem of the transition from black and white television to color, from the plane — to the volume. All of this points to the need to find new methods of transmission of a television signal. Are there opportunities in this regard? Yes, there are. It tells the modern theory and based on the statistical properties of the television signal. The current method for image transfer is sequential transfer of each of the 600 elements 000, which splits the image. This system is capable of ensuring the transmission and the more complex (ie. E. With the highest number of small parts) images that can be imagined in the form of a chessboard with a number of cells equal to the number of elements of decomposition. But the study shows that virtual images are on average much larger structure and capabilities of the system used by only a few percent. Consequently, there is a huge unnecessary stock, the elimination of which would make really big savings.
There is a second argument, based on the fact that the adjacent frames, even when sending quick movements are very similar to each other. It is clear that the transfer of the next frame, in principle, there is no need to repeat the parts of the image that remained unchanged relative to the previous frame.
To realize these opportunities should first detailed study of the statistics of TV images and signals.
Important and interesting challenges facing telephony. Studies show that modern methods of voice is even and easy, but it is extremely wasteful. You can reduce dozens of times the telephone signal, based on the principles of so-called synthetic telephony. The challenge is the objective recognition of speech sounds (phonemes); small number of phonemes, there are about 40 over the communication channel to be transmitted only the number of phonemes, so that it was synthesized based on the control signal received at the receiving end. In addition, it is necessary to convey more information about height, strength and timbre. In general, all the above possible savings.
Worthy of mention attempts to build new systems of multi-channel communications. Currently, these systems are based on two methods of signal separation: the frequency and time. However, the theory suggests that a separation of the signals on the basis of a much more general form -as. Thus, it is possible to divide the signals coinciding in time and having overlapping spectra (e.g., rectangular and triangular pulses form). It is possible that on this basis will be able to create new technical systems.
It goes without saying that the successful resolution of these and other challenges requires a deep and persistent research work.
[Iachitelnuyu role in the further improvement of a variety of wireless devices will play a wide use in their designs of semiconductor devices — diodes and transistors. Semiconductors have a significantly smaller and lighter than radio tubes do not have hot cathode, characterized by long life, and therefore increase the reliability of the radio, countable and mathematical machines and other installations.
Much work on the study of semiconductor materials and the development of new semiconductor devices is conducted at the Institute of Radio Engineering and Electronics of the Academy of Sciences of the USSR.
Editors of the magazine «Radio» addressed to the head of a department of the Institute Professor Sergey G. Kalashnikov, to tell what works with semiconductors conducted e laboratories of the Institute.
— Work with semiconductors in our laboratories is carried out in different directions, — says Professor Kalashnikov.-One of these areas — the study of the properties of germanium and silicon is the starting material for the manufacture of semiconductor devices.
Germanium, silicon and other semiconductors obtained in a pure form, suitable for use in devices. The desired properties of semiconductors acquire only with the addition of impurities — «additive» different elements. In order to consciously control the properties of semiconductors, it is necessary to investigate how the properties of different semiconductors Elihu «additive». It is very important to study the effect of these impurities on the recovery in the semiconductor electronic balance, ie. E. On the «lifetime» of electrons and holes, as well as on its resistivity. This issue, in addition to application value, and is of great scientific interest, as his tech study helps to understand the extremely important and complex phenomena of the interaction of electrons with the crystal lattice of the semiconductor, which is one of the main problems of solid state physics.
Our institute is currently conducting research in this area.
For the experiments developed special vacuum furnace to produce single crystals of silicon and germanium, and to introduce them to the various impurities, and developed a method of studying relaxation processes in semiconductors.
Another focus of our work is to study the properties of the semiconductor devices and the creation of instruments that could operate at high frequencies. In the works to study and improve the frequency characteristics of semiconductor diodes and transistors, we have had some success. Over the past few years a number of studies of equivalent circuits of semiconductor diodes in high and ultra-high frequencies.
Research on point diodes were made in the direction of studying the dependence of the input resistance and detecting the properties of the frequency, a constant positive bias on the diode and the characteristics of the input material. For junction diodes transpired influence the properties of the semiconductor material of the diode, and the mode of its rectifying properties.
The results of these studies allow us to offer an equivalent circuit of a semiconductor diode at high frequencies, which differs from the prior art. This made it possible to draw a number of conclusions on ways to improve the frequency characteristics of the diodes, which we are currently trying to implement.
One of the problems that we now decide — is to create a junction diodes, able to work at microwave frequencies. The creation of such diodes will increase the reliability of the various equipment used in these ranges.
For questions related to the application of transistors, the works are also in the direction of improving their frequency properties. The challenge for the employees of our institute is to greatly increase the operating frequency of transistors. This will give the opportunity to fully replace radio tubes in radios, televisions and other radio.
— At the conclusion of our conversation, — said Professor Kalashnikov — it should be noted that the present state of development of semiconductor technology can be compared with the development of technology of vacuum instrumentation period around 1925. If we consider that the technology of production of semiconductor devices is much more complicated than the technology of vacuum tubes, it becomes clear that there must be done a great job to solve the great challenges posed by the Directives XX Congress of the Party of the sixth five-year plan in the creation of new types of semiconductor devices .
To successfully meet these challenges will require collaboration of a large team of physicists, engineers and technicians, and I hope that many radio amateurs to take part in the important work.
In an interview with the magazine «Radio» Head of Laboratory of Semiconductor Devices professor, doctor of technical sciences Boris T. Kolomiets said:
— In the past five years our lab has done extensive work on the physical properties of different semiconductors and selection of materials, the value of conductivity that strongly influence the temperature or light. As a result, we found a number of semiconductor materials, will create new, highly sensitive electronic devices — thermistors and photoresistors.
Soon, our industry has organized the release of the developed laboratory RTD type MMM-4 MMT, MMT-8, the MMT-9, KMT KMT-1 and 4 with a large temperature coefficients range from -2.4 to — 6.0 per cent in the Ie C.
Significant progress has been made in the establishment of photoresistors. Implementation in production photoresistor type FS-A1. FS-A4, B2-FS, FS-K1-K2 and PS have a very great sensitivity, much higher than the sensitivity of vacuum photocells. For comparison, you can give an example. One of the best and most common type of solar cells NCW is sensitive only about 100 uA / lm, and the sensitivity of the photoresistor type FS-K1 at a voltage of 400 is equal to 1 200 000 uA / lm.
At present, an opportunity to create, based on cadmium selenide new photoresistors having about ten times more sensitive than the photoresistor type FS-K1.
The laboratory has already carried out a great job of finding objects and the use of thermal photoresistors. In the sixth five-year period, these surveys will be continued.
The new five-year RTD will find wide application in various fields of technology. They will be used for distance measurement and automatic temperature control for automatic thermal control and fire alarm systems for temperature compensation of the various elements of the electrical circuits and limitation of the impulse of starting currents of motors and other electrical appliances for measuring thermal conductivity of liquids and gases and their rate of flow, etc. . d.
Photoresistors successfully replace vacuum solar cells in the automation of the technological processes such as expense items on a conveyor belt, quality control and tissue paper in the process of production and in some other cases.
In carrying out the tasks set by the XX Congress of the Communist Party to Soviet science, laboratory workers will continue to explore a variety of semiconductor materials, work on creating termosbproChivlenyy having even less inertia than the existing ones to expand their range of operating temperatures, which currently range from -70 to + 180 ° C, and the reduction of the inertia of RTD, to develop new rational designs of these devices and the expansion of their scope in the national economy.
Much remains to be done in the area of photoresistors. We will continue to search for new semiconductor materials, which would allow for a further increase in the sensitivity of these devices, reduce their inertia and broaden the spectral sensitivity. It should also carry out a number of works on creation of new rational structures photoresistors, including the development and organization of production of encapsulated photoresistors, reliably operating in conditions of high humidity and liquids.
Our laboratory staff are enthusiastic honorably perform the tasks of creating new types of semiconductor devices and the widespread adoption of the national economy has developed and manufactures semiconductor industry RTD and photoresistors.
Soviet scientists at a constant and effective support of the Communist Party and the Soviet government have achieved outstanding results in a number of areas of science. One of the great achievements of our scientists is to create electronic speed computers whose significance for our country can not be overestimated.
Sergey told the following:
— The solution of many important problems arising in modern technology, due to the huge volume of complex calculations. Provide them by conventional means, using manual or electric adding machines is virtually impossible.
To imagine the full significance of the outstanding achievements of technical thought, suffice it to say that the modern electronic computer for several hours performing many calculations as an experienced evaluator can not sdelatv in my entire life.
Established at the Institute of Fine Mechanics and Computer Technology of the Academy of Sciences of the USSR-speed electronic computing machine — BESM makes an average of seven — eight thousand, ie mathematical operations per second. In other words, it replaces the work of tens of thousands of calculators, opening unlimited opportunities for scientific research institutes, design bureaus and design organizations.
Our electronic machine has been operating for about two years. In a relatively short period of time with the help of a lot of problems solved from various areas of science and technology. This will save the state hundreds of millions of rubles.
There are many examples that show what a truly irreplaceable role played by electronic computing machine if necessary to make lengthy calculations or very fast calculations.
Problems with V00.
Interestingly, 15 calculators for several months unsuccessfully tried to solve this problem for at least one option. It is not difficult to understand what it gives a great saving of time and material resources in hydraulic engineering;
Electronic computer performs not only the mathematical problems, but also can solve a number of logical problems. You can use it, for example, the translation of scientific and technical texts from one language to another. Opytnyy.perevod scientific texts from English into Russian language was implemented in late 1955. Curiously, this translation machine made faster and more competent than any of the three professional translators working simultaneously for comparison.
In computers — a great future.
We Soviet scientists are ese conditions and opportunities with honor solve this large and important task. Development of electronic automation will significantly improve the performance of electronic computers in relation to the speed of performing arithmetic operations, and with respect to reducing the amount of equipment and dimensions of the machine.

«Carefully raise radio operators"
Under the headline in the number 12 of the magazine «Radio» for 1955 it published an article by A. Mstislavsky, which noted shortcomings in the work of the Tashkent radio club DOSAAF. In particular, the article pointed out that radio club does not care about the involvement of amateur radio girls Uzbek women, ill help in the study of radio hams.
According to the editorial board deputy chairman of the Republican Committee of Uzbek SSR T DOSAAF. Zubov, the facts mentioned in the article «Carefully raise radio operators» are correct. By decision of the Presidium of the Republican Committee of Uzbek SSR T DOSAAF. Gavrilenko, who rightly subjected to criticism in the article, dismissed the chief of the Tashkent radio club.
Article A. Mstislavsky discussed at the board meeting of the Republican radio club. It outlined specific measures to address shortcomings in the work of the club.
On this evening Electrician Moscow koksoogazovogo plant Nikolai Trubkin returned from work later than usual. Despite the fatigue, his mood was upbeat. Still would! Today he made a very right thing: to help improve the design team combined heat and power electromechanical control.
The fact that the electromechanical power regulator designed nodderzhivat the water level in the boiler drum, worked intermittently. At any time it can lead to tragic consequences, as the increase or decrease of the water level in the drum threatened accident And innovator Nikolay Trubkin constructed a small electronic device, which would eliminate the impact of the work of the regulator ua play in regulating valves.
Recalling the events of the past bottom, Nicholas gratefully thought of foreman Victor CSAC, which has managed to instill in him, Nikolai, like many other workers who love radio.
• MOSCOW. The Central Radio DOSAAF group of radio amateurs under the direction t. Dmitrieva trains on the 13th All-Union Exhibition of creativity amateur radio constructors original construction winches, controlled by radio. The same group of radio amateurs has developed a radio-controlled model is manufactured n dump truck.
• Stavropol. In preparation for the 13th Funkausstellung, a radio amateur A. Bax-SRI designed the original light barrier.
A year ago, the engineer Victor CSAC organized factory radio engineering circle. To study radio engineering, many expressed a desire to work. Regularly I began to attend classes and Nikolai Trubkin. Knowledge was given is not easy, but the circle members persistently mastered the basics of radio engineering. Gradually, the young radio amateurs became a free and simple to understand, and then a more sophisticated radio equipment. Many of them are engaged in the construction. Golubev, for example, built a radio receiver N. Trubkin — his first tube meter — AAO-meter, V. Filin manufactured automatic device, triggered by the change in capacitance at the approach of man to the antenna. Forces radios circle members was one of the shops of the plant. And, especially foam, hams began to apply the knowledge gained in the circle, in their practical work.
…In the morning he came to the plant, Nikolai tubes primarily interested in how the controller worked the night shift. It turned out that his proposed device does not eliminate all the disadvantages of the regulator.
Then Trubkin CSAC and engineer decided to completely reconstruct the electromechanical regulator toyu ensure that it accurately account for the water flow coming into the loosing-electron and automatic firing exposures and move the tape to the spectral analysis. All the «five designs are tested in the laboratory spectral smelter.
• Krasnodar. Radio amateur engineer II. Poles designed instrument for measuring the level of oil in Oake turbines. Device comprising a sensor, a high geie-
Sator, tube voltmeter and nndnkaor, works by measuring the capacitance change in the level of oil rec. Radio amateur Tscherkassoff prepared a new device — hygrometer for measuring the moisture content synunih and solids.
• Armavir, Armavir Member oldest radio amateur radio club
A. Eremeev «ekoichil assembling his instrument with which exactly opredelnyutov place gasket TRU6 vodokanalizatsits. Neriye trials have shown good results which the boiler drum, timely respond to changes in water level.
It was decided to regulate the water level in boilers electronic regulator construct, without the delay which would react to changes in water level ia in the boiler drum, maintaining the amount of supplied water according to the steam flow. Procured standard amplifier of the «EU-42», a few hams transformed it, made some changes in the scheme. As sensitive elements of the sensors used electric appliances that are used to measure the flow of steam, water district level in the boiler.
Finally, the design was ready. Tests have shown good results. In the near future all boilers combined heat and power plant will be equipped with electronic power regulators.
Inspired by the success, V. and N. Trubkin CSAC continued to work on the automation of production processes. They made a new rationalization proposal- electronic pressure regulator feedwater, which automatically maintains a constant pressure injected into the boiler feed water pumps. Now these regulators work well in two turbopumps and three electric pumps.
Radio amateurs — innovators of Moscow Coke and Gas Plant are large n the right job. His rationalization proposals AIS promote widespread adoption in the electronics industry.
A dream come true
Anyone even slightly familiar with the operation of coal preparation plants, well ziaet what damage can cause the production of a small bolt, nut or a piece of wire, accidentally caught in the flow of coal supplied by conveyor belts to the crushers. That is why there are continuously powerful electromagnetic separators,
However, the use of electromagnetic separators very expensive production.
We needed a device that would have showed metallic objects in the rocks and automatically would include electromagnetic separator. Such a device was constructed in the district Leningrad Design Institute of Mechanical Processing of Minerals.
…It was in June 1953. Engineer of electrical wiring and automation of the Leningrad Institute «Giprougleobogaschenie» passionate radio amateur Sergey Sheremetinsky was sent to Makeyevka on Kalmiusskuyu central processing plant to participate in the Commission for the industrial testing of a new metal detector.
The tests took place directly in the workplace. Unfortunately, they were unsuccessful. The device is operated with large faults, and then had his forge,
It was then, returning IE trip to Leningrad engineer Sheremetinsky activist section of the introduction of radio methods in the economy of the Leningrad Radio Club, decided to create a radio-electronic devices for the detection of metallic impurities in the rocks. And so began «throes of creation,» so familiar to every radio amateur — constructor. All the free time gave Sheremetinsky development scheme Mr. designing experimental model of the metal detector. It was a long time before a radio amateur was able to start checking their device. The results of the first tests inspired inventor.
In December 1954, Scheremetinskny demonstrated his design at the enlarged meeting VNITI Instrumentation with representatives of a number of Leningrad institutes and design organizations. The meeting approved device radio amateur-iovatora and recommended it for use in the coal industry. .
And again — the trip to the Donbass, IA Voroshiloigradsky Plant named after Parkhomenko, where they were testing the device. Of course, Sheremetinsky little worried. The test will end at the plant ?. How will «lead» the device itself?
Doubts, agitated amateur radio, were not in vain. Metal, impeccably worked in the laboratory, refused at the first test in the shop magnetic separator plant. Said the industry interference. To get rid of them, Sheremetinsky made some design changes to the device. Subsequent tests have given finally positive results. The design has been approved for a typical project.
It would seem that the intended purpose is achieved. But radio amateur ua not reassured. Ou decided to improve the design to get approval. And when in the spring of 1955 Sheremetinsky Kalmiusskuyu drove to the central processing plant for industrial metal detector test, he brought with him not one, but two of his designs.
Within four months of both instruments were thoroughly tested. The advantages were of the latest design news agency. That it has approved State Commission of the Ministry of Coal Industry of the USSR.

Y’zdavia this region is famous for its wealth of mineral resources. Copper and gold, carbon and bauxite are hidden in the ground. Lots of metal, lots of minerals gives the country the northern Urals. But not . Only residents are proud Krasnoturyinsk. In the city there is no man who does not know that in Krasnoturinsk was born and spent his childhood genius ucheiy Russian physicist Alexander Stepanovich Popov, enriched mankind’s greatest invention — the radio.
The name assigned to the famous countryman Krasioturinskomu radio club DOSAAF, created recently, but has already earned a good reputation. A lot of people going in the evenings in spacious, thoughtfully equipped classrooms club. Everything here is done by the activists: made various stands with visual aids, the keys are mounted on tables, control panel.
From classes sounds of Morse telegraphy signals. Yuioshi and girls learn to make at the hearing, send key. In the laboratory work amateur radio, design new equipment.
Members of the section occupied by the short-wave radio of collective construction. Young worker Alexander Savenkov, teacher Vladimir Vladimirovich Ivanov checked the transmitter nodes. In Shortwave stressful time. In May of this year, their collective station for the first time «is published.»
The radio club many young people. Young and head of the club itself, demobilized: sailor Constantine S. Temples. The enthusiasm, the enthusiasm, the spirit of creativity and daring quest — all these qualities of youth, impose a visible imprint on all the activities of the club. Here, at the club, was born bold at first glance a dream, the dream of that in the taiga, the northern town, the main street that bears sometimes wander at night, create your own television center.
In lyubom.dele necessary first step, the first push. Only then will move to the ITO space, attracting the more and more people, generating around itself dozens and hundreds of large and small business. And, perhaps, the first step towards creating Krasioturinskogo television center was a conversation between the head of Radio Club temple and the first secretary of Party Committee of Ivan Antonovich Zhuruhiiym, a big fan of radio, a patriot of his city. Ivan Antonovich supported the idea Khramov. The concrete result of their conversation was that when Radio Club was created to TV section. It includes Zhuruhin, temples and many other hams.
While under construction in Sverdlovsk State Television Center. He was replaced by a television station made the town hams. This telecentre, constructed and assembled activists DOSAAF, successfully conducted the transfer within two years. Hams Krasnoturyinsk with a sense of deep gratitude met with a message that the Sverdlovsk radio club decided to give them a television center.
But will there be enough strength, knowledge, ability to organize television programs in the city? We think about it and Zhuruhin, and temples, and many others. We had to dismantle their own television center in Sverdlovsk, transport components and spare parts in the Red turinsk, install the antenna change with regard to the new conditions of the scheme and the station equipment to mount it.
Rapidly held the first meeting of the section TV. We discussed the possibilities, weigh the strength. And to think carefully about all the questions, unanimously decided: we can! Soon a group of radio amateurs went to Sverdlovsk acquainted with the equipment and dismantle. Krasnoturinsk began receiving components and spare parts.
We began the search space for the television station. The most suitable proved to building industrial college — one of the highest in the city. NA It is most advantageous to install the antenna. In this house, in one of the rooms on the third floor, located telecentre workshop. People of different professions and ages gathered here. All of them are united by one thing — love for radio.
Engineer Alexander A. Grevtsev, old quiet man rarely parted with the tube, amateur radio has been for many years. His eyes grew stronger and developed radio technology young Soviet country. He — the participant of the First Congress of the Friends of the radio, which was held in 1924 in Moscow, in a room of the Museum. Then Grevtsev young radio amateur, he was elected a member of the Committee of the Society of Friends of Moscow radio. Alexander A. worked as an instructor in Dmitrov, participated in the installation of radio and villages, many years served in the Signal Corps of our Armed Forces. He has long been interested in TV. In the 30s Grevtsev built his first television image scan disk Nip Cova. Working on it, Alexander A. thought about the future, about the time when television is widely spread across the country. And so the time has come.
In the workshop Grevtsev met a man whom I knew many years ago. It was managing construction trust Michael Davidovich Monastic. Back in 1924, he built a radio detector, and first among amateur radio operators received permission to use them. Grevtsev and monastery, as a young man worked in the Moscow organization of friends of Radio, now often together bending over circuits, assembled and installed equipment Television Centre.
Just another way passed Vitaly Mikhailovich Myasnikov. He was born and raised in Krasnoturinsk and still in school, from the 4th class became interested in amateur radio, he made his first odnolampovy receiver is battery powered. The hobby radio influenced his whole life. During the war, he and hobbyist Cherkasov built in his hometown radio unit 100-watt, and then converted it to trehkilovattny, worked as a district technician-mechanic broadcasting center. When Vitaly Mikhailovich heard that in the urban section of the radio club founded television, he immediately actively involved in the work. His extensive experience has brought many benefits when installing the equipment.
The move further business, the greater the activists appeared in the section. Anfalov Anatoly Pavlovich, director of electric measuring group energolaboratorii aluminum plant, a senior electrician Pyotr Andreyevich Loschitsky, deputy head of the city office communication Anatoly Gilev and many others performed in the workshop free evenings, contribute to the overall work.
Transmitters channel image and sound of the channel are mounted in a special room, fenced off in the attic of the building. It also set the frame bearing the mast.
The Soviet people have a remarkable quality, look to the future, thinking about tomorrow que. Krasnoturinsk hams telecentre mounted in such a way that later you can vary the types of transmissions. At first television center will show movies. But this is only the first time. The members of the sections are going to broadcast from the studio, and in the future — the assembly hall of the college. This is even more likely that the hardware is located next to the hall.
In the days when radio amateurs worked hard at the television station, returned from Moscow first secretary of the Party Committee Krasnoturyinsk Ivan Antonovich Zhuruhin adopted. participate in the XX. Congress of the CPSU. Soon, members of the Section gathered at a regular meeting. Ivan Antonovich shared his impressions of the Congress, he told the district that are showing great care what our Party and the Government; o steadily raising the material and cultural well-being of the Soviet people. ‘The words were met «with enthusiasm, ZyLo decided; speed up the dark, nN work. «to enter in; deystviedelevizioiny; Center Dieu radio.
From the roof of an industrial college where ,,., Is the television station tower, far away. vidio okrestr its’ path ultrakorotkievoliy. Residents of cities and Volchansk Kvrpnnska, Red mines ,. Voroitsovskii, .ne-., How many workers the villages located within a radius of 20 kilometers, will be able to receive each of the first countries of the television center.
City Krasnoturyinsk sharply divided into two halves. In the old part — small wooden houses, narrow alleys and Ulichka. And next — a new city, which grew over the past fifteen years. Here beautiful three- and four-storey house, spacious apartment with central heating; water supplies cold and hot water. Straight wide streets filled with asphalt. It stands the beautiful building of the Palace of Culture.
When you look at this city, one might think about how far forward stepped lives during the Soviet era. From small wooden shanties — a landscaped spacious and light homes; semihandicraft from plants — to large modern enterprises; the first transmitter, which worked Alexander Stepanovich Popov, before the television centers.
It is unlikely that the great inventor of radio Popov could not even dream about that in his country, in the town, which otyschesh is not on any map, you will see the TV, infinitely moved apart the walls of apartments, allowing the comfort of your home, watch new movies , performances, concerts.
Now it’s no longer a dream but a reality. Such is our life, our Soviet reality.
