Volksempfänger
The ''Volksempfänger'' (, "people's receiver") was a range of German radio receivers developed by engineer Otto Griessing at the request of Joseph Goebbels, the Reich Minister of Propaganda of the Nazi regime. The purpose of the ''Volksempfänger'' program was to make radio reception technology affordable to the general public. Goebbels realized the great propaganda potential of this relatively new medium and thus considered widespread availability of receivers highly important. History The original ''Volksempfänger'' VE301"VE301" is an abbreviation where the "VE" stands for "Volksempfänger" and the "301" refers to the date of 30 January 1933 – the day of the Nazis seized power in the ''Machtergreifung''. model was presented on August 18, 1933, at the 10. ''Große Deutsche Funkausstellung'' in Berlin. The VE301 was available at a readily affordable price of (equivalent to two weeks' average salary), and a cheaper model (only a little more than the average weekly wage ...

Otto Griessing
Otto Griessing (born 19 January 1897 in Munich – died 11 November 1958 in Überlingen) was a German electronics engineer. He became known following his design of the so-called Volksempfänger (people's receiver), one of the sets on display at the 10th German Radio Show (Internationale Funkausstellung Berlin) in August 1933. He designed the receiver at the request of Joseph Goebbels, the German Propaganda Minister. More Volksempfängers were manufactured in Germany between 1933 and 1945 than any other model. The budget-priced Deutsche Kleinempfänger (German small receiver) was also widely known as the Volksempfänger. Life Son of a Bavarian NCO, Otto Griessing was educated in Munich, enlisting as a volunteer in 1914 and serving as a signaller. He reached the rank of lieutenant and saw active service on the eastern and western fronts. He was posted to the Near East and interned following the armistice with Turkey. From 1919 he studied at Würzburg Polytechnic, now the Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internationale Funkausstellung Berlin
The IFA ( ) or Internationale Funkausstellung Berlin (International radio exhibition Berlin, a.k.a. 'Berlin Radio Show') is one of the oldest industrial exhibitions in Germany. Between 1924 and 1939 it was an annual event, but from 1950 it was held every other year until 2005. Since then it has become an annual event again, held in September. Today it is one of world's leading trade shows for consumer electronics and home appliances. It offers the opportunity to exhibitors to present their latest products and developments to the general public. As a result of daily reporting in almost all the German media, the radio exhibition and the showcased technology receives a large amount of attention around the globe. In the course of its history, many world innovations were first seen at the exhibition. IFA is "Europe’s biggest tech show". 245,000 visitors and 1,645 exhibitors attended IFA 2015.

Joseph Goebbels
Paul Joseph Goebbels (; 29 October 1897 – 1 May 1945) was a German Nazi politician who was the ''Gauleiter'' (district leader) of Berlin, chief propagandist for the Nazi Party, and then Reich Minister of Propaganda from 1933 to 1945. He was one of Adolf Hitler's closest and most devoted acolytes, known for his skills in public speaking and his deeply virulent antisemitism, which was evident in his publicly voiced views. He advocated progressively harsher discrimination, including the extermination of the Jews in the Holocaust. Goebbels, who aspired to be an author, obtained a Doctor of Philology degree from the University of Heidelberg in 1921. He joined the Nazi Party in 1924, and worked with Gregor Strasser in its northern branch. He was appointed ''Gauleiter'' of Berlin in 1926, where he began to take an interest in the use of propaganda to promote the party and its programme. After the Nazis came to power in 1933, Goebbels's Propaganda Ministry quickly gained a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strength Through Joy
NC Gemeinschaft (KdF; ) was a German state-operated leisure organization in Nazi Germany.Richard Grunberger, ''The 12-Year Reich'', p. 197, It was part of the German Labour Front (german: link=no, Deutsche Arbeitsfront), the national labour organization at that time. Set up in November 1933 as a tool to promote the advantages of Nazism to the German people and internationally, while also being utilized to ease the process of the rearmament of Germany. It was also intended to compensate for the poor increases in wages and for the loss of trade union rights. Through its structure of organized events and promotion of propaganda, it was also intended to prevent dissident and anti-state behavior. By 1939, it had become the world's largest tourism operator. KdF was composed of several departments that had its own specific goals, with each department organizing different leisure activities. It organized activities such as sporting events on factory floors, art exhibitions, discounted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reichs-Rundfunk-Gesellschaft
The Reichs-Rundfunk-Gesellschaft (RRG; ''Reich Broadcasting Corporation'') was a national network of German regional public radio and television broadcasting companies active from 1925 until 1945. RRG's broadcasts were receivable in all parts of Germany and were used extensively for Nazi propaganda after 1933. Historical recordings of RRG broadcasts are today held by the German Broadcasting Archive. History The company was established in Berlin on 15 May 1925 with a start capital of 100,000 Reichsmark as an umbrella organisation by nine regional broadcasters – that is to say, all of the German radio stations other than the Deutsche Stunde in Bayern – serving the various states of the Weimar Republic. From 1926, a majority share was held by the state-owned Deutsche Reichspost authority, represented by RF engineer and Reichspostministerium official Hans Bredow as chairman in the rank of a ''Reichs-Rundfunk-Kommissar''. The logo of the RRG was designed by German graphic de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regenerative Circuit
A regenerative circuit is an amplifier circuit that employs positive feedback (also known as regeneration or reaction). Some of the output of the amplifying device is applied back to its input so as to add to the input signal, increasing the amplification. One example is the Schmitt trigger (which is also known as a regenerative comparator), but the most common use of the term is in RF amplifiers, and especially regenerative receivers, to greatly increase the gain of a single amplifier stage. The regenerative receiver was invented in 1912 and patented in 1914US Patent 1113149A, Edwin H. Armstrong, Wireless receiving system', filed October 29, 1913, granted October 6, 1914 by American electrical engineer Edwin Armstrong when he was an undergraduate at Columbia University. It was widely used between 1915 and World War II. Advantages of regenerative receivers include increased sensitivity with modest hardware requirements, and increased selectivity because the Q of the tuned ...

Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...

Radio Receiver
In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves of radio frequency) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation. Radio receivers are essential components of all systems that use radio. The information produced by the receiver may be in the form of sound, video (television), or digital data. A radio receiver may be a separate piece of electronic equipment, or an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Nazi Germany
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which Hitler and the Nazis referred to as the Thousand-Year Reich, ended in May 1945 after just 12 years when the Allies defeated Germany, ending World War II in Europe. On 30 January 1933, Hitler was appointed chancellor of Germany, the head of gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vacuum Tubes
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplification and current rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—from the cathode to the anode. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
