[edit] Australia

In 1906, the Marconi Company constructed an experimental station at Queenscliff, Victoria, successfully communicating between the Australian continent and Devonport, Tasmania. This station operated on a temporary basis; subsequent Australian wireless efforts would be undertaken by Amalgamated Wireless Australasia, established in 1913 under ownership of Marconi, its commercial arch-rival Telefunken and Australian local business interests.

[edit] Canada

Marconi Company had owned or operated Canadian coast radio stations since 1902, either as trans-Atlantic radiotelegraph links or as marine radio stations. While eastern Canada's ship-to-shore coastal stations were government-owned after 1915, the Marconi Company had been paid to continue to operate the facilities. Canada's west coast had been served by government-operated stations since 1907; many stations in the Canadian Arctic were military operations.

The Canadian Marconi Company operated manufacturing facilities at Montreal, Quebec and in 1919 had established on an experimental basis the first commercial broadcast radio station, XWA.^[1] This operation would become CFCF (AM/FM/TV) and CFCX (shortwave); Marconi would be forced to sell the stations due to foreign-ownership restrictions imposed on Canadian broadcast stations in 1970. The manufacturing operation is now CMC Electronics.

Since 1954, the federal Department of Transport has operated former Marconi coastal stations in eastern Canada; most served the Great Lakes and the Atlantic coast:

• VAY Cape Hopes Advance, Ungava Bay^[2] (July 1, 1929 - )
• VBC Midland, Ontario^[3] (July 8, 1912 - )
• VBH Kingston, Ontario^[4] (January 9, 1914 - )
• VBK Trois-Rivières, Québec
• VCC Québec, Québec^[5] (1910 - )
• VCD Grosse Île, Québec^[6](until 1927)
• VCI Heath Point, Anticosti Island^[7] (July 21, 1904 - 1921)
• VCO North Sydney, Nova Scotia^[8] (1907 - )

[edit] Glace Bay, Nova Scotia

On December 15, 1902 Marconi established trans-Atlantic communication between Table Head in Glace Bay, Nova Scotia and Poldhu in Cornwall, England using a 60 kilowatt transmitter and four 210-foot towers. The site was expanded and moved inland in 1904-05, increasing both antenna size and transmitter power. Transatlantic Radio Service between the Marconi Towers and Clifden, Ireland was inaugurated in October 1907, and continued until the Marconi Station (operating under callsign VAS, Voice of the Atlantic Seaboard) was shut down and the property sold in 1946. The site of the Marconi Towers Station is now used to house a museum.^[9]

[edit] Halifax, Nova Scotia

In 1905, Marconi constructed a wireless station at Camperdown, Halifax, Nova Scotia (original callsign HX, MHX from 1907-1912, VCS thereafter). From 1905 until 1926, this station was to collect traffic from Sable Island (VCT) and Cape Sable (VCU) for manual retransmission via dedicated landline telegraph circuit to Halifax (AX).^[10] VCS later would serve as a coast guard marine radio station.

[edit] Louisbourg, Nova Scotia

As the original, powerful spark gap transmitters would create large quantities of electrical interference, stations could not transmit and receive at the same time - even if different wavelengths were used. By 1913, the increasing amount of trans-Atlantic radio telegraph traffic required that existing half-duplex operation be upgraded to a link which could carry messages in both directions at the same time. This was done by geographically separating the receiving stations from the existing transmitter sites; new receiving stations at Letterfrack, Ireland and Louisbourg, Nova Scotia effectively doubled the capacity of the Marconi Company to carry trans-Atlantic telegraph traffic. Instead of the 500 kHz and 1 MHz frequencies common in shipboard radio at the time, Marconi was to use longwave frequencies of 37.5 kHz for transmission from Glace Bay, Cape Breton, Nova Scotia to Letterfrack and 54.5 kHz for transmission from Clifden, Ireland to Louisbourg in order to establish reliable transatlantic communication day and night.^[11]

Antennas for longwave radio reception were to occupy huge amounts of land at these sites; while Lee DeForest's work had produced a vacuum tube (or "Audion") as early as 1906, many key advances in electronic amplifiers (which would allow smaller receiving antennas and more efficient transmitter designs) would only be made once improved communications became a military necessity during World War I. The design and construction of tuned circuits able to separate radio signals transmitted and received at different frequency and wavelength had also shown great improvement.

By 1919, improved transmitting and receiving tubes had made transatlantic voice transmission possible. By 1926 Marconi would be able to use shortwave radio to link the British Empire, making the former long-wave transatlantic service and its Louisbourg receiving station obsolete. The Marconi Towers transmitter site on Cape Breton was upgraded to broadcast voice and operated until 1945; the Louisbourg station closed in 1926.

[edit] Pointe-au-Père, Québec

As the nominal point of entry to the St. Lawrence River from the sea, Pointe-au-Père has hosted four lighthouse stations since 1859.^[12] A Marconi radiotelegraph station was constructed in 1909. Arriving trans-Atlantic liners would unload mail and take on harbour pilots; Pointe-au-Père also provided a hydrographic station and a quarantine post.^[13]

On May 29, 1914 the Pointe-au-Père Marconi station received an SOS call from the RMS Empress of Ireland, a Canadian passenger liner which, surrounded by fog, had been hit by Norwegian coal freighter SS Storstad. "May have struck ship... listing terribly" reported Marconi operators Edward Bamford and Ronald Ferguson,^[14] notifying rescuers on shore of their position twenty miles seaward of Rimouski^[15] as the vessel rapidly took on water. In 14 minutes, this collision was to claim 1,012 lives.

[edit] France

On 27 March 1899, Marconi transmitted from Wimereux, Bologne, France the first international wireless message which was received at the South Foreland Lighthouse near Dover, United Kingdom.^[16]

[edit] Ireland

In 1902, a Marconi telegraphic station was established in the village of Crookhaven, County Cork, Ireland to provide marine radio communications to ships arriving from the Americas. A ship's master could contact shipping line agents ashore to enquire which port was to receive their cargo without the need to come ashore at what was the first port of landfall.^[17]

Ireland was also, due to its western location, to play a key role in early efforts to send trans-Atlantic messages.

[edit] Clifden, Galway

As existing submarine cable operators in the early 1900s had held a monopoly on international telegraph service to Newfoundland, Marconi's first regular trans-Atlantic wireless service was established on October 17, 1907 between Derrygimla Bog, Clifden, Galway, Ireland and Glace Bay, Nova Scotia.^[18] An additional Marconi receiving station in Letterfrack, Ireland had operated from 1913 until 1916.^[19]

On June 15, 1919, the first non-stop trans-Atlantic airplane crossing by Capt. John Alcock and Lt. Arthur Brown left Newfoundland and arrived at the Marconi site in Clifden, Ireland.^[20]

[edit] Ballybunion

Additional facilities were constructed at Ballybunion, Ireland in 1914 and employed during World War I. In March 1919, the first Marconi broadcast of voice by longwave radio, made from Marconi's station YXQ at Ballybunion using vacuum tubes instead of the spark gap transmitters formerly used in radiotelegraph operation, was heard as far as Chelmsford and Louisburg, Nova Scotia.^[21]

Due to destruction caused by the Irish Civil War in 1922, traffic formerly carried at Clifden was permanently redirected via Caernarvon, Wales, a link which remained in service until replaced by more modem technology in the 1930s. The Marconi Station at Ballybunion was also to cease operation.

[edit] India

A Marconi radiotelegraph station had been operational at Delhi, India at the time the Indian capital had moved there from Calcutta in 1911.^[22] Marconi had constructed experimental broadcast transmitters in Calcutta, which were to become 2BZ (Calcutta Radio Club, 1923) and 5AF (West Bengal government); these radio stations operated until the national government established a station in 1927.^[23]

[edit] Italy

On November 13, 1910 the first radio message to Africa was sent from a radiotelegraph station at Coltano, Italy and received in Massaua (then part of Ethiopia). Italy's King Vittorio Emanuele officially opened the station in 1911, at which time messages were sent from Coltano to Glace Bay and Massaua.^[24]

[edit] Newfoundland

The first Marconi transatlantic message was received in 1901 at Signal Hill, St. John's, Newfoundland. Subsequent efforts at trans-Atlantic communications would use Cape Breton, Nova Scotia as a Canadian terminus due to the Anglo-American Telegraph Company's entrenched monopoly in the Dominion of Newfoundland. Messages for ships at sea would continue to be handled in Newfoundland, due to its strategic location as point of first contact in the east. As of 1915, the following coastal stations were operational in Newfoundland to connect the island to otherwise-isolated outports in Labrador and to handle vital ship-to-shore communication:^[25]

• VCE Cape Race^[26] (1904-1966, originally CE or MCE)
• VCM Belle Island
• VCR Cape Ray
• VOA Battle Harbour, Labrador^[27]
• VOB Venison Island
• VOC American Tickle
• VOD Domino
• VOE Grady
• VOF Smokey Tickle
• VOG Holton
• VOH Cape Harrison
• VOI Makkovik
• VOJ Fogo (1912-1933)^[28]
• VOJH Corner Brook^[29] (1940-1974)
• VON Cabot Tower/Signal Hill, St. John's (until 1960^[30])

[edit] Newfoundland coastal stations

All radio stations licensed by the Dominion of Newfoundland after 1912 and before the April 1st, 1949 confederation bear callsigns beginning with VO.

Stations built by the Marconi Company of Canada in outlying areas such as Fogo (VOJ) were funded by the Dominion of Newfoundland and served to report ice and weather conditions, provide communications with sealing vessels and transmit messages from Newfoundland to Labrador coastal fisheries. By the 1930s, original spark gap transmitter equipment at these sites would have been removed due to severe interference caused to broadcast radio operations.

[edit] Cape Race and Cape Ray

Canadian Marconi Company stations with Canadian VC calls did exist on Newfoundland in the wireless telegraph era, even though Newfoundland was not part of the Dominion of Canada. These stations were permitted by Newfoundland authorities to operate solely in communication with ships at sea; trans-Atlantic radiotelegraph service to land-based stations in the United Kingdom and Europe operated from Cape Breton in Canada.

Exploiting a strategic location at the south-easternmost part of Newfoundland, the Cape Race (VCE) station could serve as a vital first point of contact for arriving ships in the New World, as well as providing telegram service to trans-Atlantic passenger liners.^[31] Messages received from travellers crossing the Atlantic could be relayed in a timely fashion to much of North America, including major cities such as New York, long before a ship's arrival.^[32] A lighthouse and direction-finding radio were also once active at this site^[33]

The Cape Race site, active as a coast radio station until 1966, is now home to the Myrick Communications Museum and a radioamateur commemorative station, VO1MCE. A copy of April 1912 station logs (documenting communication between Cape Race and RMS Titanic) appear in the Marine Museum of the Atlantic in Halifax, Nova Scotia.

The Cape Ray (VCR) and Belle Isle (VCM) stations, which played a similar role, served ocean-going liners in the Gulf of St. Lawrence.

[edit] Spain

On February 1, 1912 a new Marconi station erected at Aranjuez near Madrid, Spain transmitted a message from King Alfonso which would be received at Poldhu, Cornwall, England for delivery to the London correspondent of the New York Times.^[34]

[edit] South Africa

In the Boer War era of 1899, Marconi wireless equipment would face one of its first tests in military deployment with mixed results. Initial attempts to deploy land-based military radio were problematic, but the five Marconi installations in March 1900 on naval cruisers HMS Dwarf, Forte, Magicienne, Racoon and Thetis proved successful.^[35]

By 1912, Marconi stations covered Aden, Algeria, Australia, Azores, Belgium, Brazil, Burma, China, Curacao, France, French Guyana, Germany, India, Italy, Japan, Jamaica, Mexico, Morocco, Netherlands, Norway, Romania, Russia, Senegal, South Africa, Sweden, Tobago, Trinidad, Uruguay, Zanzibar, and the Pacific Ocean.^[36] Efforts in 1926 to build an Imperial Wireless Chain spanning the globe would bring new construction of Marconi wireless facilities to much of the British Empire, including South Africa and India. Shortwave radio would deployed as a means to communicate internationally with smaller transmitters and more directional antennas than had been possible on the former longwave system. These directional-antenna (or "beam antenna") installations were known as the Imperial Beam system; Marconi Beam as a geographic place name still refers to a section of modern Cape Town, South Africa, as one location where such facilities historically had operated.

[edit] United Kingdom

In December 1898, the Marconi Company opened the first wireless factory at Chelmsford in Essex. Marconi stations in the United Kingdom would be the first to be received internationally in France and later Newfoundland. A message received in 1910 in the UK from Marconi-equipped ship S.S. Montrose, then en route to Canada, would prove key to the arrest of fugitive Hawley Harvey Crippen.^[37]

[edit] Poldhu, Cornwall

Marconi's station at Poldhu, Cornwall, England, initially constructed in October 1900 on a cliff in a remote location to avoid publicity during initial experimentation, had by 1901 transmitted messages to ships at sea over distances of more than 200 miles. On December 12, 1901, the first trans-Atlantic message from the Poldhu Wireless Station was received at St. John's in the Dominion of Newfoundland, some 1800 miles distant.^[38] The station was dismantled in 1933.^[39] A Marconi memorial remains at this site today.^[40][41]

[edit] Dover, Kent

In 1898, Marconi began tests of ship-to-shore communication between Trinity House Lighthouse, Dover, Kent, England and the East Goodwin lightship. In 1899, South Foreland Lighthouse at St. Margaret's Bay, Dover was used by Guglielmo Marconi to receive the first international transmission (from Wimereux, France). Dover received the first ship-to-shore message (from the East Goodwin lightship) and the first ship-to-shore distress message (when a steamship ran into the same lightship, and the lighthouse relayed the message up the coast to the Walmer lifeboat).

[edit] Newhaven, East Sussex

The Newhaven Marconi Radio Station was established at Newhaven, East Sussex in 1904, and started running in 1905. The station achieved ship to shore radio communications around 1912.

[edit] Tetney, Lincolnshire

A station at Tetney, Lincolnshire, England, constructed as part of a larger system linking nations of the British Empire, established shortwave communications with Australia in April 1927 and India in September 1927.^[42]

[edit] Caernarvon, Wales

The Caernarvon station (callsign MUU) transmitted a 200 kW signal directed toward Montréal; by 1918, advances in vacuum tube amplifiers allowed this signal to be received by the Amalgamated Wireless Australasia station at "Logan Brae", Pymble in Sydney, Australia.^[43]

In 1922, the Marconi transmitting station at Caernarvon, Wales was to replace the former station at Clifden, Galway, Ireland for trans-Atlantic message traffic during the Irish Civil War. The Marconi Station at Clifden was never rebuilt.^[19]

[edit] Snowdonia, Wales

In 1914, the Marconi Wireless and Telegraph Company constructed a 400 kW wireless transmitting station to send trans-Atlantic messages to the US from ten 400-foot masts atop Cefndu mountain. The station served throughout World War I and remained in operation until 1939. On September 22, 1918 the first wireless telegraph message to Australia was sent from Snowdonia.^[44]

A receiving station was situated 40 miles further south at Towyn.

[edit] United States

The Marconi Wireless Telegraph Company of America (American Marconi), incorporated in New Jersey in 1899, had by 1908 deployed five land stations and 40 marine stations. It would operate wireless stations until, with the entry of the United States into World War I, the US Navy assumed wartime control of radio. It would continue manufacturing activities until American Marconi was acquired by General Electric in 1919, forming the Radio Corporation of America.^[45]

[edit] New Jersey

Marconi's trans-Atlantic radiotelegraph stations were deployed in pairs; a station near New Brunswick, New Jersey would transmit while another at Belmar would receive the weak signals from across the ocean. American Marconi had also established a factory in 1907 in Aldene, New Jersey.

New Brunswick Marconi Station (40°30′55″N 74°29′20″W / 40.51529°N 74.48895°W / 40.51529; -74.48895) was located at JFK Boulevard and Easton Avenue just a few minutes from the New Brunswick border in Somerset, New Jersey. Today it is the site of Marconi Park. It was an early radio transmitter facility built in 1913 and operated by the American Marconi Wireless Corporation.^[46] After the partial failure of transatlantic telegraph cables, the facility was confiscated by the US Navy in January, 1918 to provide transatlantic communications during World War I. The New Brunswick Naval Radio Station was the principal wartime communication link between the United States and Europe, using the callsign NFF. President Woodrow Wilson's Fourteen Points speech was transmitted from the site in 1918. After the war, ownership of the station, along with Marconi's other US assets, were transferred from the Navy to RCA. The antenna masts were demolished in 1952 to make room for what is now a small mall containing a Kmart, but the buildings on the other side of JFK Boulevard were spared. All but one of the brick buildings were demolished around 2004 to make way for a storage locker facility. The bricks and tiles were saved for use in any future restoration of the spared building, and the second facility in Belmar, New Jersey.

The Belmar Marconi station was located at what are now Camp Evans buildings in Belmar, New Jersey.^[47] The original buildings were built by the American Marconi Company under a contract to the J.G. White Engineering Corp. between 1912 and 1914 as part of Guglielmo Marconi's "wireless girdle"^[48] around the Earth. It was then known as the Belmar Station (40°11′09″N 74°03′34″W / 40.1859°N 74.0594°W / 40.1859; -74.0594). The Belmar Station served as Marconi's receiving station, "duplexed" with his New Brunswick (40°30′55″N 74°29′20″W / 40.5153°N 74.4889°W / 40.5153; -74.4889) high power transmitting station. An operator in Belmar keyed the New Brunswick transmitter, 32 miles (51 km) to the northwest, through a landline connection. Edwin Armstrong and David Sarnoff tested and perfected the regenerative circuit at the Belmar site, on the night of January 31/February 1, 1914. Albert Hoyt Taylor, who later made important contributions toward the development of radar, was Communication Superintendent at the station during World War I. The station was closed in 1924, after technological improvements enabled the New Brunswick station to both transmit and receive.^[49]

[edit] New York

As early as March 1, 1904, messages for steamship passengers at sea were accepted at Western Union landline telegraph offices, where they would be transmitted overland to Sagaponack or Babylon, New York and delivered to Marconi Wireless Telegraph for transmission to steamships of the Cunard Line, American Line, French Line, North German Lloyd Line, Atlantic Transport Line, Hamburg-American Line or Red Star Line.^[50]

In 1912, a Marconi station atop the Wannamaker's Department Store building in New York City was to receive a list of Titanic passengers aboard the RMS Carpathia, delivering the news to Hearst newspapers before the ship's arrival. An operator at this station, David Sarnoff, would go on to lead the Radio Corporation of America.^[51]

As an aside, the Belmar Marconi station also served as a base to the Klu Klux Klan.

[edit] Cape Cod, Massachusetts

A Marconi station built in 1902 at South Wellfleet, Cape Cod, Massachusetts (callsign WCC, also identified pre-1912 as MCC, initially CC) transmitted its first telegraphic message via spark gap transmitter in 1903 from what is now known as "Marconi Beach". Marine radio traffic carried before the station closed in 1917 included news and telegrams for passengers of the Lusitania,^[52] distress calls from the RMS Titanic in 1912 and a message to the British king in 1903. Antennas and equipment were dismantled in 1920, replaced by a newer station in Chatham, Massachusetts.^[53] The former site is now part of the Cape Cod National Seashore.^[54]

[edit] Point Reyes, California

WCC is just one of two former Marconi stations on US national parkland; a California coastal radio station (callsign KPH), formerly operated by Marconi and later RCA, is located at Point Reyes National Seashore.^[55]

In 1913, an American Marconi Company transmitting station was established at Bolinas. The receiving station KPH was about twenty miles further north, at Point Reyes. In 1914, the stations at Bolinas and Marshall would allow messages received from New Brunswick, New Jersey to be retransmitted to Hawaii.^[56]

KPH has been preserved by volunteers and is operated at weekends and on special occasions such as International Marconi Day and the anniversary of the "end of commercial Morse code in America." The station volunteers also use the alternative callsign KSM and amateur radio club callsign K6KPH.

[edit] Hawaii

Marconi's radiotelegraph was to serve both as a means of establishing communications between the various Hawaiian Islands and as a means to receive messages from the Americas (notably California and Panama) for retransmission to Japan and Asia. In 1912, the Marconi Company proposed what it billed as "A Wireless Girdle around the Earth";^[57] proposing that as a station in Great Britain could communicate with one in Belmar, New Jersey (serving New York City), that station in turn could reach Panama and from there a signal could be sent to Hawaii. A powerful station constructed in Hawaii could by 1914 reach San Francisco, California, receiving messages which could be transmitted to the Philippines once a later station was constructed there.^[58] From Manila, Philippines, messages eventually could be resent to a British station in Singapore which would then reach Bangalore, India. From there, a signal sent to a station in Africa could eventually be retransmitted to Egypt or Cyprus, and the Egyptian station would reach London.

In 1915, the New York Times announced "The opening of the Japanese Marconi wireless plant at Funabashi near Yokohama with messages on Tuesday to the Marconi station at Koko Head, Hawaii, extended the Marconi service nearly two-thirds the way around the globe. If the war had not interfered with the creation of the British Imperial chain, it might have been possible by this time to relay a message by wireless all the way around the world."^[59] A Marconi station at Kahuku on the North Shore of Oahu, Hawaii was later operated by RCA; the site was re-purposed as an air base during World War II and is now abandoned.^[60]
