Dynatron Radio Ltd
Dynatron Radio Ltd was the trade name used by H.Hacker & Sons for their wireless products. The firm started trading in 1927 and operated independently until being bought by Ekco in 1955. The rights to the Dynatron name are currently held by Roberts Radio. Dynatron was also a successful business with making record players; most of them were made in the sixties and seventies. Priced in the pro-sumer market sector, the average household would have had to save the equivalent of three weeks salary to buy one. Early history The Hacker brothers, Ron (born 1908) and Arthur (born 1910), shared a strong interest in radio, and started a company producing high quality radiograms and wireless receivers at the ages of just 19 and 17 respectively. As they were too young to become directors of a company, the firm was set up using their father's name, Harry Hacker, in 1927. The firm began in a room above the family grocery shop on Maidenhead High Street, and the first product emerged in 1928 - the ...

Ekco
EKCO (from Eric Kirkham Cole Limited) was a British electronics company producing radio and television sets from 1924 until 1960. Expanding into plastic production for its own use, Ekco Plastics produced both radio cases and later domestic plastic products; the plastics company became Lin Pac Mouldings Ltd. Early history The company's founder Eric Kirkham Cole was born on 4 July 1901 at Prittlewell, Southend-on-Sea, Essex, and was educated at Southend Day Technical School, followed by a three-year apprenticeship. Cole and his future wife Muriel Bradshaw started out making radio sets in 1924.Oxford Dictionary of National Biography: Cole, Eric Kirkham by Rowland F. Pocock William Streatfield Verrells, a schoolmaster and freelance journalist from Southend-on-Sea, wrote an article in a local newspaper asking if it was possible to power a radio set from the mains electricity supply rather than batteries. Cole saw a possible business opportunity and set about building his battery e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roberts Radio
Roberts Radio is a British consumer electronics company that produces radios and related audio equipment. Based in Mexborough, the company has been making radios since its foundation in 1932 and claim to be the oldest active radio manufacturer in the UK. History Roberts Radio was founded in 1932 by Harry Roberts (1910-1969) of Mile End and Leslie Bidmead of Kilburn. They financed the down payment on a small factory in London's Soho by selling Bidmead's motorbike. A few years later they moved across Oxford Street to no. 41 Rathbone Place. During the Blitz in the Second World War, they moved to East Molesey in Surrey. During this time the majority of production shifted from domestic radios to morse code tappers. Roberts resumed producing domestic radios after the war and eventually gained a reputation of quality. They received a Royal Warrant to the Queen in 1955 and later another to the Queen Mother and the Prince of Wales in the 1980s. Another warrant was granted via the purch ...

Radiogram (furniture)
In British English, a radiogram is a piece of furniture that combined a radio and record player. The word ''radiogram'' is a portmanteau of ''radio'' and '' gramophone''. The corresponding term in American English is console. Popularity Radiograms reached their peak of popularity in the post-war era, supported by a rapidly growing interest in records. Originally they were made of polished wood to blend with the furniture of the 1930s, with many styled by the leading designers of the day. An expensive instrument of entertainment for the house, fitted with a larger loudspeaker than the domestic radio, the radiogram soon began to develop features such as the record autochanger, which would accept six or seven records and play them one after another. Certain recordings could be ordered as a box set which would combine the recorded piece in order, to suit an autochanger set-up. In the 1940s and 1950s, sales of the radiogram, coupled with the then-new F.M. waveband, and the advent o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maidenhead
Maidenhead is a market town in the Royal Borough of Windsor and Maidenhead in the county of Berkshire, England, on the southwestern bank of the River Thames. It had an estimated population of 70,374 and forms part of the border with southern Buckinghamshire. The town is situated west of Charing Cross, London and east-northeast of the county town of Reading, Berkshire, Reading. The town differs from the Maidenhead (UK Parliament constituency), Parliamentary constituency of Maidenhead, which includes a number of outer suburbs and villages (including parts of Wokingham and Reading) such as Twyford, Berkshire, Twyford, Charvil, Remenham, Ruscombe and Wargrave. History The antiquary John Leland (antiquary), John Leland claimed that the area around Maidenhead's present town centre was a small Roman settlement called Alaunodunum. He stated that it had all but disappeared by the end of the Roman occupation. Although his source is unknown, there is documented and physical evidence ...

Tuned Radio Frequency Receiver
A tuned radio frequency receiver (or TRF receiver) is a type of radio receiver that is composed of one or more tuned radio frequency (RF) amplifier stages followed by a detector (demodulator) circuit to extract the audio signal and usually an audio frequency amplifier. This type of receiver was popular in the 1920s. Early examples could be tedious to operate because when tuning in a station each stage had to be individually adjusted to the station's frequency, but later models had ganged tuning, the tuning mechanisms of all stages being linked together, and operated by just one control knob. By the mid 1930s, it was replaced by the superheterodyne receiver patented by Edwin Armstrong. Background The TRF receiver was patented in 1916 by Ernst Alexanderson. His concept was that each stage would amplify the desired signal while reducing the interfering ones. Multiple stages of RF amplification would make the radio more sensitive to weak stations, and the multiple tuned circuit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superheterodyne Receiver
A superheterodyne receiver, often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency. It was long believed to have been invented by US engineer Edwin Armstrong, but after some controversy the earliest patent for the invention is now credited to French radio engineer and radio manufacturer Lucien Lévy. Virtually all modern radio receivers use the superheterodyne principle; except those software-defined radios using ''direct sampling''. History Heterodyne Early Morse code radio broadcasts were produced using an alternator connected to a spark gap. The output signal was at a carrier frequency defined by the physical construction of the gap, modulated by the alternating current signal from the alternator. Since the output frequency of the alternator was generally in the audible range, this produces an audible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gee (navigation)
Gee, sometimes written GEE, was a radio navigation system used by the Royal Air Force during World War II. It measured the time delay between two radio signals to produce a fix, with accuracy on the order of a few hundred metres at ranges up to about . It was the first hyperbolic navigation system to be used operationally, entering service with RAF Bomber Command in 1942. Gee was devised by Robert Dippy as a short-range blind landing system to improve safety during night operations. During development by the Telecommunications Research Establishment (TRE) at Swanage, the range was found to be far better than expected. It then developed into a long-range, general navigation system. For large, fixed targets, such as the cities that were attacked at night, Gee offered enough accuracy to be used as an aiming reference without the need to use a bombsight or other external references. Jamming reduced its usefulness as a bombing aid, but it remained in use as a navigational aid in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Member Of The Most Excellent Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service. It was established on 4 June 1917 by King George V and comprises five classes across both civil and military divisions, the most senior two of which make the recipient either a knight if male or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order. Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceased recommendations for appointments to the Order of the British Empire when they cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hacker Radio Ltd
Hacker Radio Limited manufactured domestic radio and audio equipment. The company was formed in Maidenhead by brothers Ron and Arthur Hacker in 1959, and traded successfully until 1977. Financial difficulties resulted in the company being sold and relaunched with the name Hacker Sound which closed in 1979. History The Hacker brothers, Ron (born 1908) and Arthur (born 1910), founded Dynatron in the late 1920s with help from their father Harry, but in 1955 Ekco took over the company, which at the time employed 150 people. By 1959, the number of employees had risen to 250, but the Hacker brothers were uncomfortable with the arrangements and decided to set up their own company, Hacker Radio Limited. In December 1960 Ekco merged with Pye, then Pye was bought by Philips in 1967. In 1981, Roberts Radio bought Dynatron from Philips. The Hacker brothers acquired a factory in Cox Green, Maidenhead, and started producing a range of transistor portable radios, beginning with the RP10 Her ...
