Wireless telegraphy or radiotelegraphy is the transmission of text messages by radio waves , analogous to electrical telegraphy using cables . Before about 1910, the term wireless telegraphy was also used for other experimental technologies for transmitting telegraph signals without wires. In radiotelegraphy, information is transmitted by pulses of radio waves of two different lengths called "dots" and "dashes", which spell out text messages, usually in Morse code . In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves. At the receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code.
119-531: The Imperial Wireless Chain was a strategic international communications network of powerful long range radiotelegraphy stations, created by the British government to link the countries of the British Empire . The stations exchanged commercial and diplomatic text message traffic transmitted at high speed by Morse code using paper tape machines. Although the idea was conceived prior to World War I ,
238-468: A beat frequency ( heterodyne ) at the difference between the two frequencies is produced: f BEAT = | f IN − f BFO | {\displaystyle f_{\text{BEAT}}=|f_{\text{IN}}-f_{\text{BFO}}|} . If the BFO frequency is near enough to the radio station's frequency, the beat frequency is in the audio frequency range and can be heard in
357-469: A telegraph key , which turned the transmitter on and off, producing short ("dot") and long ("dash") pulses of radio waves, groups of which comprised the letters and other symbols of the Morse code. At the receiver, the signals could be heard as musical "beeps" in the earphones by the receiving operator, who would translate the code back into text. By 1910, communication by what had been called "Hertzian waves"
476-518: A telegraph line linking distant stations was very expensive, and wires could not reach some locations such as ships at sea. Inventors realized if a way could be found to send electrical impulses of Morse code between separate points without a connecting wire, it could revolutionize communications. The successful solution to this problem was the discovery of radio waves in 1887, and the development of practical radiotelegraphy transmitters and receivers by about 1899. Over several years starting in 1894,
595-568: A Dominion ended when Canadian parliament declared war on Germany on 9 September 1939, separately and distinctly from the United Kingdom's declaration of war six days earlier. By the 1950s, the term Dominion of Canada was no longer used by the United Kingdom, which considered Canada a "Realm of the Commonwealth". The government of Louis St. Laurent ended the practice of using Dominion in the statutes of Canada in 1951. This began
714-400: A constant sine wave generated by an electronic oscillator in the receiver called a beat frequency oscillator (BFO). The frequency of the oscillator f BFO {\displaystyle f_{\text{BFO}}} is offset from the radio transmitter's frequency f IN {\displaystyle f_{\text{IN}}} . In the detector the two frequencies subtract, and
833-647: A copy of any Federal legislation that has been assented to. Then, within two years after the receipt of this copy, the (British) Monarch in Council could disallow an Act. Thirdly, at least four pieces of Imperial legislation constrained the Canadian legislatures. The Colonial Laws Validity Act of 1865 provided that no colonial law could validly conflict with, amend, or repeal Imperial legislation that either explicitly, or by necessary implication, applied directly to that colony. The Merchant Shipping Act of 1894, as well as
952-473: A fixed amount of transoceanic telegram traffic, reducing the revenue of the cable companies and possibly bankrupting them. Parliament ruled out the creation of a private monopoly to provide the service and concluded that no government department was in a position to do so, and the Treasury were reluctant to fund the creation of a new department. Contracting the construction to a commercial "wireless company"
1071-731: A licence of a different class. As of 2021, licence Class A in Belarus and Estonia, or the General class in Monaco, or Class 1 in Ukraine require Morse proficiency to access the full amateur radio spectrum including the high frequency (HF) bands. Further, CEPT Class 1 licence in Ireland, and Class 1 in Russia, both of which require proficiency in wireless telegraphy, offer additional privileges:
1190-509: A matter of urgency. An expert committee also advised that Marconi were the only company with technology that was proven to operate reliably over the distances required (in excess of 2,000 miles (3,200 km)) "if rapid installation and immediate and trustworthy communication be desired". After further negotiations prompted by Treasury pressure, a modified contract was ratified by Parliament on 8 August 1913, with 221 Members of Parliament voting in favour, 140 against. The course of these events
1309-565: A means of communication. Continuous wave (CW) radiotelegraphy is regulated by the International Telecommunication Union (ITU) as emission type A1A. The US Federal Communications Commission issues a lifetime commercial Radiotelegraph Operator License. This requires passing a simple written test on regulations, a more complex written exam on technology, and demonstrating Morse reception at 20 words per minute plain language and 16 wpm code groups.

When the key was pressed, it would connect a battery to the telegraph line, sending current down the wire. At the receiving office, the current pulses would operate a telegraph sounder , a device that would make a "click" sound when it received each pulse of current. The operator at

1666-781: A new federation named Canada from 1867. This was instituted by the British Parliament in the British North America Act, 1867 (see also Canadian Confederation ) . Section 3 of the Act referred to the new entity as a "Dominion", the first such entity to be created. From 1870 the Dominion included two vast neighbouring British territories without self-government: Rupert's Land and the North-Western Territory ; together these became over time
1785-531: A new modulation method: continuous wave (CW) (designated by the International Telecommunication Union as emission type A1A). As long as the telegraph key was pressed, the transmitter produced a continuous sinusoidal wave of constant amplitude. Since all the radio wave's energy was concentrated at a single frequency, CW transmitters could transmit further with a given power, and also caused virtually no interference to transmissions on adjacent frequencies. The first transmitters able to produce continuous wave were
1904-597: A president of Ireland. At the same time, a law delegating functions to the King, not as King in Ireland but as the symbol of the co-operation amongst Commonwealth countries with which Ireland associated itself, continued to apply in external relations. The last statutory functions of the King with respect to Ireland were abolished in 1949 . The Balfour Declaration of 1926 , and the subsequent Statute of Westminster , 1931, restricted Britain's ability to pass or affect laws outside of its own jurisdiction. Until 1931, Newfoundland

However, the report was not acted upon. While British politicians procrastinated, Marconi constructed stations for other nations, linking North and South America, as well as China and Japan, in 1922. In January 1922
2142-506: A receiver's earphone, this sounded like a musical tone, rasp or buzz. Thus the Morse code "dots" and "dashes" sounded like beeps. Damped wave had a large frequency bandwidth , meaning that the radio signal was not a single frequency but occupied a wide band of frequencies. Damped wave transmitters had a limited range and interfered with the transmissions of other transmitters on adjacent frequencies. After 1905 new types of radiotelegraph transmitters were invented which transmitted code using
2261-495: A shorter and more desirable call sign in both countries, and the right to use a higher transmit power in Russia. Efforts to find a way to transmit telegraph signals without wires grew out of the success of electric telegraph networks, the first instant telecommunication systems. Developed beginning in the 1830s, a telegraph line was a person-to-person text message system consisting of multiple telegraph offices linked by an overhead wire supported on telegraph poles . To send
2380-465: A standard part of radiotelegraphy receivers. Each time the radio was tuned to a different station frequency, the BFO frequency had to be changed also, so the BFO oscillator had to be tunable. In later superheterodyne receivers from the 1930s on, the BFO signal was mixed with the constant intermediate frequency (IF) produced by the superheterodyne's detector. Therefore, the BFO could be a fixed frequency. Continuous-wave vacuum tube transmitters replaced
2499-665: A substantive role as a representative of the British government, and ultimate executive power was vested in the British Monarch —who was advised only by British ministers in its exercise. Canada's independence came about as each of these sub-ordinations was eventually removed. When the Dominion of Canada was created in 1867, it was granted powers of self-government to deal with all internal matters, but Britain still retained overall legislative supremacy. This Imperial supremacy could be exercised through several statutory measures. In

Thus, for example, the British Ireland Act 1949 , recognised that the Republic of Ireland had "ceased to be part of His Majesty's dominions". The foundation of "Dominion" status followed the achievement of internal self-rule in British Colonies, in the specific form of full responsible government (as distinct from " representative government "). Colonial responsible government began to emerge during

Wireless telegraphy or radiotelegraphy, commonly called CW ( continuous wave ), ICW (interrupted continuous wave) transmission, or on-off keying , and designated by the International Telecommunication Union as emission type A1A or A2A , is a radio communication method. It was transmitted by several different modulation methods during its history. The primitive spark-gap transmitters used until 1920 transmitted damped waves , which had very wide bandwidth and tended to interfere with other transmissions. This type of emission

The constitutional scholar Andrew Heard argues that Confederation did not legally change Canada's colonial status to anything approaching its later status of a Dominion. At its inception in 1867, Canada's colonial status
3094-479: Is that it was achieved with a minimum of legislative amendments. Much of Canada's independence arose from the development of new political arrangements, many of which have been absorbed into judicial decisions interpreting the constitution—with or without explicit recognition. Canada's passage from being an integral part of the British Empire to being an independent member of the Commonwealth richly illustrates
3213-516: Is the 2nd most popular mode of amateur radio communication, accounting for nearly 20% of contacts. This makes it more popular than voice communication, but not as popular as the FT8 digital mode, which accounted for 60% of amateur radio contacts made in 2021. Since 2003, knowledge of Morse code and wireless telegraphy has no longer been required to obtain an amateur radio license in many countries, it is, however, still required in some countries to obtain
3332-634: The Canadian Citizenship Act, 1946 , following which the British Nationality Act 1948 created Commonwealth citizenship and the Dominions subsequently created their own citizenships. As Heard later explained, the British government seldom invoked its powers over Canadian legislation. British legislative powers over Canadian domestic policy were largely theoretical and their exercise was increasingly unacceptable in

The British government of Lloyd George had emphasised the use of the capital "D" when referring to
3570-815: The British Chambers of Commerce added their voice to the demands for action, adopting a resolution urging the government to urgently resolve the matter, as did other organisations such as the Empire Press Union , which claimed that the Empire was suffering "incalculable loss" in its absence. Under this pressure, after the 1922 General Election , the Conservative government commissioned the Empire Wireless Committee, chaired by Sir Robert Donald , to "consider and advise upon

While not then accepted, the Marconi proposal created serious interest in the concept. A dilemma faced by Britain throughout the negotiations to establish the chain was that Britain owned the largest network of submarine telegraph cables . The proposed stations would directly compete with cables for

In the period leading up to World War I , long distance radiotelegraphy became a strategic defense technology, as it was realized that a nation without radio could be isolated by an enemy cutting its submarine telegraph cables , as indeed happened during the war. Starting around 1908, industrialized nations built global networks of powerful transoceanic wireless telegraphy stations to exchange Morse code telegram traffic with their overseas colonies. In 1910

The rise to the status of a Dominion and then full independence for Canada and other possessions of the British Empire did not occur by the granting of titles or similar recognition by the British Parliament but by initiatives taken by the new governments of certain former British dependencies to assert their independence and to establish constitutional precedents. What is remarkable about this whole process

Later India , Pakistan , and Ceylon (now Sri Lanka ) also became dominions for short periods. With the transition of the British Empire into the Commonwealth of Nations after World War II, it was decided that the term Commonwealth country should formally replace dominion for official Commonwealth usage. This decision

By this stage, however, three of the original stations had been closed, after the service was centralised during 1939–1940 at Dorchester and Somerton. The longwave Rugby radio station continued to remain under Post Office ownership throughout. The shortwave Imperial Wireless Chain "beam stations" operated in pairs; one transmitting and one receiving. Pairs of stations were sited at (transmitters first): At Bodmin and Bridgwater, each aerial stretched to nearly half

International travel and commerce were transacted through British embassies and consulates. For example, matters concerning visas and lost or stolen passports of Dominion citizens were carried out at British diplomatic offices. In the late 1930s and early 1940s, Dominion governments established their own embassies,

An "Imperial Wireless and Cable Conference" was therefore held in London in January 1928, with delegates from the United Kingdom, the self-governing Dominions, India, the Crown Colonies and Protectorates, to "examine
8925-640: The first place, the British North America Act of 1867 provided in Section 55 that the Governor General may reserve any legislation passed by the two Houses of Parliament for "the signification of Her Majesty's pleasure", which is determined according to Section 57 by the British Monarch in Council. Secondly, Section 56 provides that the Governor General must forward to "one of Her Majesty's Principal Secretaries of State" in London
9044-600: The first two of which were established by Australia and Canada in Washington, D.C. , in the United States. Until 1948 any resident of a British colony or Dominion had the status of British subject . In 1935 the Irish Nationality and Citizenship Act created a separate status of Irish national , but stopped short of creating a full citizenship. Canada was the first to create its own citizenship with
9163-573: The four separate Australian colonies— New South Wales , Tasmania , Western Australia , South Australia —and New Zealand could gain full responsible government were set out by the British government in the Australian Constitutions Act 1850 . The Act also separated the Colony of Victoria (in 1851) from New South Wales. During 1856, responsible government was achieved by New South Wales, Victoria, South Australia, and Tasmania, and New Zealand. The remainder of New South Wales
9282-487: The greater scope of British law, because acts pertaining to "Dominion status", such as the Statute of Westminster 1931 , have not been repealed in both the United Kingdom and historic Dominions such as Canada. The term "within the crown's dominions" continues to apply in British law to those territories in which the British monarch remains head of state, and the term "self-governing dominion" is used in some legislation. When
9401-620: The idea through his experiments with wireless induction. However, the backing was withdrawn when Marconi formed the Wireless Telegraph & Signal Company . GPO lawyers determined that the system was a telegraph under the meaning of the Telegraph Act and thus fell under the Post Office monopoly. This did not seem to hold back Marconi. After Marconi sent wireless telegraphic signals across the Atlantic Ocean in 1901,
9520-407: The key was pressed was just an unmodulated carrier wave , it made no sound in a receiver's earphones. To receive a CW signal, some way had to be found to make the Morse code carrier wave pulses audible in a receiver. This problem was solved by Reginald Fessenden in 1901. In his "heterodyne" receiver, the incoming radiotelegraph signal is mixed in the receiver's detector crystal or vacuum tube with
9639-664: The mid-19th century. The legislatures of Colonies with responsible government were able to make laws in all matters other than foreign affairs, defence and international trade, these being powers which remained with the Parliament of the United Kingdom . Nova Scotia soon followed by the Province of Canada (which included modern southern Ontario and southern Quebec ) were the first colonies to achieve responsible government, in 1848. Prince Edward Island followed in 1851, and New Brunswick and Newfoundland in 1855. All except for Newfoundland and Prince Edward Island agreed to form
9758-432: The new shortwave technology. Parliament finally approved an agreement between the Post Office and Marconi to build beam stations to communicate with Canada, South Africa, India and Australia, on 1 August 1924. From when the Post Office began operating the "Post Office Beam" services, through to March, 31st, 1929, they had earned gross receipts of £813,100 at a cost of £538,850, leaving a net surplus of £274,250. Even before
9877-583: The new, larger country. However, neither the Confederation nor the adoption of the title of "Dominion" granted extra autonomy or new powers to this new federal level of government. Senator Eugene Forsey wrote that the powers acquired since the 1840s that established the system of responsible government in Canada would simply be transferred to the new Dominion government: By the time of Confederation in 1867, this system had been operating in most of what
9996-440: The only type of radio transmission during the first few decades of radio, called the "wireless telegraphy era" up until World War I , when the development of amplitude modulation (AM) radiotelephony allowed sound ( audio ) to be transmitted by radio. Beginning about 1908, powerful transoceanic radiotelegraphy stations transmitted commercial telegram traffic between countries at rates up to 200 words per minute. Radiotelegraphy
10115-423: The other types of transmitter with the availability of power tubes after World War I because they were cheap. CW became the standard method of transmitting radiotelegraphy by the 20s, damped wave spark transmitters were banned by 1930 and CW continues to be used today. Even today most communications receivers produced for use in shortwave communication stations have BFOs. The International Radiotelegraph Union
10234-483: The phasing out of the use of Dominion , which had been used largely as a synonym of "federal" or "national" such as "Dominion building" for a post office, "Dominion-provincial relations", and so on. The last major change was renaming the national holiday from Dominion Day to Canada Day in 1982. Official bilingualism laws also contributed to the disuse of Dominion , as it has no acceptable equivalent in French. While
10353-546: The policy to be adopted as regards an Imperial wireless service so as to protect and facilitate public interest." Its report was presented to the Postmaster-General on 23 February 1924 The committee's recommendations were similar to those of the Norman Committee – that any stations in the United Kingdom used to communicate with the Empire should be in the hands of the state, that they should be operated by
10472-473: The purely colonial status of the Dominions. The Irish Free State , set up in 1922 after the Anglo-Irish War , was the third Dominion to appoint a non-UK born, non-aristocratic Governor-General when Timothy Michael Healy , following the tenures of Sir Gordon Drummond in Canada and of Sir Walter Edward Davidson and Sir William Allardyce in Newfoundland, took the position in 1922. Dominion status
10591-467: The receiver's earphones. During the "dots" and "dashes" of the signal, the beat tone is produced, while between them there is no carrier so no tone is produced. Thus the Morse code is audible as musical "beeps" in the earphones. The BFO was rare until the invention in 1913 of the first practical electronic oscillator, the vacuum tube feedback oscillator by Edwin Armstrong . After this time BFOs were
10710-631: The receiving location, Morse code is audible in the receiver 's earphone or speaker as a sequence of buzzes or beeps, which is translated back to text by an operator who knows Morse code. With automatic radiotelegraphy teleprinters at both ends use a code such as the International Telegraph Alphabet No. 2 and produced typed text. Radiotelegraphy is obsolete in commercial radio communication, and its last civilian use, requiring maritime shipping radio operators to use Morse code for emergency communications, ended in 1999 when
10829-541: The receiving station who knew Morse code would translate the clicking sounds to text and write down the message. The ground was used as the return path for current in the telegraph circuit, to avoid having to use a second overhead wire. By the 1860s, the telegraph was the standard way to send most urgent commercial, diplomatic and military messages, and industrial nations had built continent-wide telegraph networks, with submarine telegraph cables allowing telegraph messages to bridge oceans. However installing and maintaining
10948-421: The revenue which had been forecast, resulting in low dividends and an inability to reduce the rates charged to customers as much as had been expected. To ease the financial pressure, the British Government finally decided to transfer the beam stations to Cable and Wireless, in exchange for 2,600,000 of the 30,000,000 shares in the company, under the provisions of the Imperial Telegraphs Act 1938 . The ownership of
11067-554: The self-governing countries was recognised in the Imperial Conference of 1907 which, on the motions of the Prime Ministers of Canada and Australia, introduced the idea of the Dominions as self-governing countries by referring to Canada and Australia as Dominions. It also retired the name "Colonial Conference" and mandated that meetings take place regularly to consult the Dominions in running the foreign affairs of
11186-578: The separate Colony of Natal .) Following the Second Boer War (1899–1902), the British Empire assumed direct control of the Boer Republics , but transferred limited self-government to Transvaal in 1906, and the Orange River Colony in 1907. The Commonwealth of Australia was recognised as a Dominion in 1901, and the Dominion of New Zealand and the Dominion of Newfoundland were officially given Dominion status in 1907, followed by
11305-566: The situation which arose as a result of the competition of the Imperial Beam Wireless Services with the cable services of various parts of the empire, to report upon it and to make recommendations with a view to a common policy being adopted by the various governments concerned." It concluded that the cable companies would not be able to compete in an unrestricted market, but that the cable links remained of both commercial and strategic value. It therefore recommended that
11424-410: The status of Dominion in the same year. These were followed by the Union of South Africa in 1910. The Order in Council annexing the island of Cyprus in 1914 declared that, from 5 November 1914, the island "shall be annexed to and form part of His Majesty's dominions". Dominion status was formally accorded to Canada, Australia, New Zealand, Newfoundland, South Africa, and the Irish Free State at
11543-416: The system began being used for regular communication including ship-to-shore and ship-to-ship communication. With this development, wireless telegraphy came to mean radiotelegraphy , Morse code transmitted by radio waves. The first radio transmitters , primitive spark gap transmitters used until World War I, could not transmit voice ( audio signals ). Instead, the operator would send the text message on
11662-533: The term may be found in older official documents, and the Dominion Carillonneur still tolls at Parliament Hill , it is now hardly used to distinguish the federal government from the provinces or (historically) Canada before and after 1867. Nonetheless, the federal government continues to produce publications and educational materials that specify the currency of these official titles. The Constitution Act, 1982 does not mention and does not remove
11781-435: The title, and therefore a constitutional amendment may be required to change it. The word Dominion has been used with other agencies, laws, and roles: Notable Canadian corporations and organisations (not affiliated with government) that have used Dominion as a part of their name have included: Ceylon , which, as a Crown colony, was originally promised "fully responsible status within the British Commonwealth of Nations",
11900-575: The various colonies they incorporated could have done separately. They provided a new model which politicians in New Zealand, Newfoundland, South Africa, Ireland, India, Malaysia could point to for their own relationship with Britain. Ultimately, "[Canada's] example of a peaceful accession to independence with a Westminster system of government came to be followed by 50 countries with a combined population of more than 2-billion people." Issues of colonial self-government spilled into foreign affairs with
12019-561: The way in which fundamental constitutional rules have evolved through the interaction of constitutional convention, international law, and municipal statute and case law. What was significant about the creation of the Canadian and Australian federations was not that they were instantly granted wide new powers by the Imperial centre at the time of their creation; but that they, because of their greater size and prestige, were better able to exercise their existing powers and lobby for new ones than
12138-474: The wishes of the opposition and officials in London. The governments of the states (colonies before 1901) remained under the Commonwealth but retained links to the UK until the passage of the Australia Act 1986 . The term Dominion is employed in the Constitution Act, 1867 (originally the B ritish North America Act, 1867 ), and describes the resulting political union. Specifically, the preamble of
12257-571: Was able to use it to its advantage during the conflict. With the end of the war and the Dominions continuing to apply pressure on the government to provide an "Imperial wireless system", the House of Commons agreed in 1919 that £170,000 should be spent constructing the first two radio stations in the chain, in Oxfordshire (at Leafield ) and Egypt (in Cairo), to be completed in early 1920 – although in
12376-427: Was banned by 1934, except for some legacy use on ships. The vacuum tube (valve) transmitters which came into use after 1920 transmitted code by pulses of unmodulated sinusoidal carrier wave called continuous wave (CW), which is still used today. To receive CW transmissions, the receiver requires a circuit called a beat frequency oscillator (BFO). The third type of modulation, frequency-shift keying (FSK)
12495-467: Was being universally referred to as " radio ", and the term wireless telegraphy has been largely replaced by the more modern term "radiotelegraphy". The primitive spark-gap transmitters used until 1920 transmitted by a modulation method called damped wave . As long as the telegraph key was pressed, the transmitter would produce a string of transient pulses of radio waves which repeated at an audio rate, usually between 50 and several thousand hertz . In
12614-506: Was disrupted somewhat by the Marconi scandal , when it was alleged that highly placed members of the governing Liberal party had used their knowledge of the negotiations to indulge in insider trading in Marconi shares. The outbreak of World War I led to the suspension of the contract by the government. Meanwhile Germany successfully constructed its own wireless chain before the war, at a cost equivalent to two million pounds sterling , and
12733-542: Was divided in three in 1859, a change that established most of the present borders of NSW; the Colony of Queensland , with its own responsible self-government, and the Northern Territory (which was not granted self-government prior to federation of the Australian Colonies). Western Australia did not receive self-government until 1891, mainly because of its continuing financial dependence on
12852-431: Was for many years the only reliable form of communication between many distant countries. The most advanced standard, CCITT R.44 , automated both routing and encoding of messages by short wave transmissions. Today, due to more modern text transmission methods, Morse code radiotelegraphy for commercial use has become obsolete. On shipboard, the computer and satellite-linked GMDSS system have largely replaced Morse as
12971-480: Was given formal legal recognition in 1942 (when the Statute of Westminster was adopted retroactively to the commencement of the Second World War in 1939). In 1930, the Australian prime minister, James Scullin , reinforced the right of the overseas Dominions to appoint native-born governors-general, when he advised King George V to appoint Sir Isaac Isaacs as his representative in Australia, against
13090-404: Was made during the 1949 Commonwealth Prime Ministers' Conference when India was intending to become a republic , so that both types of governments could become and remain full members of the Commonwealth, and this term hence refers to the realms and republics. After this the term dominion , without its legal dimension, stayed in use thirty more years for those Commonwealth countries which had
13209-610: Was marked by political and legal subjugation to British Imperial supremacy in all aspects of government—legislative, judicial, and executive. The Imperial Parliament at Westminster could legislate on any matter to do with Canada and could override any local legislation, the final court of appeal for Canadian litigation lay with the Judicial Committee of the Privy Council in London, the Governor General had
13328-484: Was never popular in the Irish Free State where people saw it as a face-saving measure for a British government unable to countenance a republic in what had previously been the United Kingdom of Great Britain and Ireland . Successive Irish governments undermined the constitutional links with the United Kingdom. In 1937 Ireland, as it renamed itself, adopted a new republican constitution that included powers for
13447-858: Was referred to as a colony of the United Kingdom, as for example, in the 1927 reference to the Judicial Committee of the Privy Council to delineate the Quebec-Labrador boundary. Full autonomy was granted by the United Kingdom parliament with the Statute of Westminster in December 1931. By the request of Australia and New Zealand, the Statute of Westminster was not applied automatically to those two Dominions until their own parliaments confirmed it. Being economically close to Britain and dependent on it for defence, they did not do so until 1942 for Australia and 1947 for New Zealand . In 1934, following Newfoundland's economic collapse, and with
13566-652: Was renamed as Cable & Wireless Limited, with Cable and Wireless Limited being renamed as Cable and Wireless (Holding) Limited. From the beginning of April 1928 the beam services were operated by the Post Office as agent for Imperial and International Communications Limited. The 1930s saw the arrival of the Great Depression , as well as competition from the International Telephone and Telegraph Corporation and affordable airmail . Due to such factors Cable and Wireless were never able to earn
13685-515: Was something between that of a colony and a state". With the adoption of the Statute of Westminster 1931 , Britain and the Dominions (except Newfoundland) formed the British Commonwealth of Nations . Dominions asserted full legislative independence, with direct access to the Monarch as Head of State previously reserved only for British governments. It also recognised autonomy in foreign affairs, including participation as autonomous countries in
13804-551: Was the favoured option, and a contract was signed with Marconi's Wireless Telegraph Company in March 1912. The government then found itself facing severe criticism and appointed a select committee to examine the topic. After hearing evidence from the Admiralty , War Office , India Office , and representatives from South Africa , the committee unanimously concluded that a "chain of Imperial wireless stations" should be established as
13923-602: Was unofficially established at the first International Radiotelegraph Convention in 1906, and was merged into the International Telecommunication Union in 1932. When the United States entered World War I, private radiotelegraphy stations were prohibited, which put an end to several pioneers' work in this field. By the 1920s, there was a worldwide network of commercial and government radiotelegraphic stations, plus extensive use of radiotelegraphy by ships for both commercial purposes and passenger messages. The transmission of sound ( radiotelephony ) began to displace radiotelegraphy by
14042-438: Was used for long-distance person-to-person commercial, diplomatic, and military text communication throughout the first half of the 20th century. It became a strategically important capability during the two world wars since a nation without long-distance radiotelegraph stations could be isolated from the rest of the world by an enemy cutting its submarine telegraph cables . Radiotelegraphy remains popular in amateur radio . It
14161-463: Was used mainly by radioteletype networks (RTTY). Morse code radiotelegraphy was gradually replaced by radioteletype in most high volume applications by World War II . In manual radiotelegraphy the sending operator manipulates a switch called a telegraph key , which turns the radio transmitter on and off, producing pulses of unmodulated carrier wave of different lengths called "dots" and "dashes", which encode characters of text in Morse code .
