Wireless Set No. 19
The Wireless Set No. 19 was a Second World War mobile radio transceiver designed for use by Armoured warfare, armoured troops of the British Army. First introduced in 1940, the No. 19 began to replace the pre-war Wireless Set No. 11. Two modified versions were introduced, Mk. II in 1941 and Mk. III in 1942. An improved version from Canada was introduced in 1942 for use primarily with other forces. In British service, the No. 19 was replaced in the post-war era by the Larkspur radio system. Canadian-built No. 19's saw continued service for many years with a variety of users. Purpose Designed for use in tanks and armoured vehicles, the radio provided three communication channels: *The A set provided longer range communications within the squadron or regiment.Military Training Pamphlet No.41, July 1940 *The B set or "troop set" provided short range communication between tanks in a troop. *The IC channel provided internal communication between crewmembers inside the tank.

Wireless Set No
Wireless communication (or just wireless, when the context allows) is the transfer of information between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio ''wireless technology'' include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications involve other electromagnetic phenomena, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The English language, the Anglican Church, and Engli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Danish Army
The Royal Danish Army ( da, Hæren, fo, Herurin, kl, Sakkutuut) is the land-based branch of the Danish Defence, together with the Danish Home Guard. For the last decade, the Royal Danish Army has undergone a massive transformation of structures, equipment and training methods, abandoning its traditional role of anti-invasion defence, and instead focusing on out of area operations by, among other initiatives, reducing the size of the conscripted and reserve components and increasing the active (standing army) component, changing from 60% support structure and 40% operational capability, to 60% combat operational capability and 40% support structure. When fully implemented, the Danish army will be capable of deploying 1,500 troops permanently on three different continents continuously, or 5,000 troops for a shorter period of time, in international operations without any need for extraordinary measures such as parliamentary approval of a war funding bill.

Dutch Army
The Royal Netherlands Army ( nl, Koninklijke Landmacht) is the land branch of the Netherlands Armed Forces. Though the Royal Netherlands Army was raised on 9 January 1814, its origins date back to 1572, when the was raised – making the Dutch standing army one of the oldest in the world. It fought in the Napoleonic Wars, World War II, the Indonesian War of Independence, and the Korean War and served with NATO on the Cold War frontiers in West-Germany from the 1950s to the 1990s. Since 1990, the army has been sent into the Iraq War (from 2003) and into the War in Afghanistan, as well as deployed in several United Nations' peacekeeping missions (notably with UNIFIL in Lebanon, UNPROFOR in Bosnia-Herzegovina and MINUSMA in Mali). The tasks of the Royal Netherlands Army are laid out in the Constitution of the Netherlands: defend the territory of the Kingdom of the Netherlands (including the Dutch Caribbean) and of its allies, protect and advance the international legal order ...

Amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It may increase the power significantly, or its main effect may be to boost the voltage or current (power, voltage or current amplifier). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a greater amplitude signal at its output. The ratio of output to input voltage, current, or power is termed gain (voltage, current, or power gain). An amplifier, by definition has gain greater than unity (if the gain is less than unity, the device is an attenuator). An amplifier can either be a separate piece of equipment or an electrical circuit contained within another device. Amplification is fundamental to modern electronics, and amplifiers are widely used in almost all electronic equipment. Amplifiers can be categorize ...

Royal Armoured Corps
The Royal Armoured Corps is the component of the British Army, that together with the Household Cavalry provides its armour capability, with vehicles such as the Challenger 2 Tank and the Scimitar Reconnaissance Vehicle. It includes most of the Army's armoured regiments, both the Royal Tank Regiment and those converted from old horse cavalry regiments.Forty p. 63. Today it comprises twelve regiments, eight regular and four reserve. Although the Household Cavalry Regiment (the Life Guards and the Blues and Royals) provide an armoured regiment, they are not part of the RAC. History The RAC was created on 4 April 1939, just before World War II started, by combining regiments from the cavalry of the line which had mechanised with the Royal Tank Corps (renamed Royal Tank Regiment). As the war went on and other regular cavalry and Territorial Army Yeomanry units became mechanised, the corps was enlarged. A significant number of infantry battalions also converted to the armoured r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frequency Modulation
Frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. The technology is used in telecommunications, radio broadcasting, signal processing, and Run-length limited#FM: .280.2C1.29 RLL, computing. In Analog signal, analog frequency modulation, such as radio broadcasting, of an audio signal representing voice or music, the instantaneous frequency deviation, i.e. the difference between the frequency of the carrier and its center frequency, has a functional relation to the modulating signal amplitude. Digital data can be encoded and transmitted with a type of frequency modulation known as frequency-shift keying (FSK), in which the instantaneous frequency of the carrier is shifted among a set of frequencies. The frequencies may represent digits, such as '0' and '1'. FSK is widely used in computer modems, such as fax modems, telephone caller ID systems, garage door openers, and other low-frequency transmissions. R ...

Lend-Lease
Lend-Lease, formally the Lend-Lease Act and introduced as An Act to Promote the Defense of the United States (), was a policy under which the United States supplied the United Kingdom, the Soviet Union and other Allied nations with food, oil, and materiel between 1941 and 1945. It was given on the basis that such help was essential for the defense of the United States; this aid included warships and warplanes, along with other weaponry. It was signed into law on March 11, 1941, and ended on September 20, 1945. In general, the aid was free, although some hardware (such as ships) were returned after the war. Canada, already a belligerent, supplemented its aid to Great Britain with a similar, smaller program called Mutual Aid. A total of $50.1 billion (equivalent to $ in ) worth of supplies was shipped, or 17% of the total war expenditures of the U.S. In all, $31.4 billion went to the United Kingdom, $11.3 billion to the Soviet Union, $3.2 billion to France, $1.6 billion to Chin ...

Canadian Marconi
The Marconi Company was a British telecommunications and engineering company that did business under that name from 1963 to 1987. Its roots were in the Wireless Telegraph & Signal Company founded by Italian inventor Guglielmo Marconi in 1897, which underwent several changes in name after mergers and acquisitions. The company was a pioneer of wireless long distance communication and mass media broadcasting, eventually becoming one of the UK's most successful manufacturing companies. In 1999, its defence equipment manufacturing division, Marconi Electronic Systems, merged with British Aerospace (BAe) to form BAE Systems. In 2006, financial difficulties led to the collapse of the remaining company, with the bulk of the business acquired by the Swedish telecommunications company, Ericsson.
