Hanso Idzerda
Hanso Schotanus á Steringa Idzerda (26 September 1885 – 2 November 1944) was a Dutch scientist, entrepreneur and pioneer in radio technology. Between 1907 and 1917 he worked to introduce the already invented triode into radio technology. In 1919 Idzerda invented the triode IDZ-lamp, which was capable of transmitting and receiving radio messages containing the human voice. On 6 November 1919 he held the first public airing of a radio programme. His programme consisted of music, and him talking for a bit in between pieces. The PCGG transmitter he invented was capable of transmitting signals from The Hague all the way to England. Herman de Man, later to be an important author and radio maker, was present. From then on the programme aired every week. In 1922 the '' Daily Mail'' decided to sponsor Idzerda, who previously financed the operation with his own money and some donations. After the ''Daily Mail'' ceased its support Idzerda's company went bankrupt. On 2 November 1944, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Triode
A triode is an electronic amplifying vacuum tube (or ''valve'' in British English) consisting of three electrodes inside an evacuated glass envelope: a heated filament or cathode, a grid, and a plate (anode). Developed from Lee De Forest's 1906 Audion, a partial vacuum tube that added a grid electrode to the thermionic diode ( Fleming valve), the triode was the first practical electronic amplifier and the ancestor of other types of vacuum tubes such as the tetrode and pentode. Its invention founded the electronics age, making possible amplified radio technology and long-distance telephony. Triodes were widely used in consumer electronics devices such as radios and televisions until the 1970s, when transistors replaced them. Today, their main remaining use is in high-power RF amplifiers in radio transmitters and industrial RF heating devices. In recent years there has been a resurgence in demand for low power triodes due to renewed interest in tube-type audio systems b ...

Radio Programme
A radio program, radio programme, or radio show is a segment of content intended for broadcast on radio. It may be a one-time production or part of a periodically recurring series. A single program in a series is called an episode. Radio networks International radio In the 1950s, a small but growing cohort of rock and pop music fans, dissatisfied with the BBC's output, would listen to Radio Luxembourg, but to some extent and probably not enough to have any impact on the BBC's monopoly and invariably only at night, when the signal from Luxembourg was stronger. During the post-1964 period, western Europe offshore radio (such as Radio Caroline broadcasting from ships at anchor or abandoned forts) helped to supply the demand for the pop and rock music. The BBC launched its own pop music station, BBC Radio 1, in 1967. The international broadcasts became highly popular in major world languages. Of particular impact were programmes by BBC World Service, Voice of America, Radio Mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PCGG
PCGG (also known as the Dutch Concerts station) was a radio station located at The Hague in the Netherlands, which began broadcasting a regular schedule of entertainment programmes on 6 November 1919. The station was established by engineer Hanso Idzerda, and is believed to have been Europe's first sustained broadcasting station, as well as one of the first stations in the world to transmit entertainment intended for a general audience. PCGG's schedule generally featured one or two evening programmes per week. Although located on the west coast of Holland, the station had a large audience across the English Channel in Great Britain. However, Idzerda ran into financial difficulties, and PCGG's licence was revoked on 11 November 1924, one month before his company, ''Nederlandsche Radio-Industrie'', shut down due to bankruptcy. History Formation Hans Idzerda was an electrical engineer, who worked with the Philips manufacturing company during World War I. (Holland was a neutral coun ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

V-2 Rocket
The V-2 (german: Vergeltungswaffe 2, lit=Retaliation Weapon 2), with the technical name ''Aggregat 4'' (A-4), was the world’s first long-range guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a "vengeance weapon" and assigned to attack Allied cities as retaliation for the Allied bombings of German cities. The rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944. Research into military use of long-range rockets began when the graduate studies of Wernher von Braun attracted the attention of the Wehrmacht. A series of prototypes culminated in the A-4, which went to war as the . Beginning in September 1944, over 3,000 were launched by the Wehrmacht against Allied targets, first London and later Antwerp and Liège. According to a 2011 BBC documentary, the attacks ...
