/////////////////////////////////////////// Historic Transatlantic Contact: Posted: 10 Dec 2016 04:50 PM PST http://www.eham.net/articles/38212 On 11 December 2016 a special amateur radio event will commemorate the 95th anniversary of the first transatlantic shortwave reception between Greenwich, Connecticut, and Ardrossen, Scotland. On that day in 1921, a radio signal transmitted from a Radio Club of America (RCA) test station -- located in a small shack on the property of Minton Cronkhite, 1BCG in Greenwich -- was received in Ardrossen as part of a series of ARRL transatlantic tests. The special event will begin at 1200 on Sunday 11 December and end at 0300 UTC on 12 December. It will include an attempt at a two-way contact between N1BCG (the commemorative call sign being used in Greenwich) and GB2ZE, operated by Jason O'Neill, GM7VSB, in Ardrossen. It is hoped the contact will take place during the afternoon of 11 December on 20m, if conditions allow. /////////////////////////////////////////// Mysteries at the Museum: Sending Code, Victorian Style: Posted: 10 Dec 2016 04:49 PM PST http://www.eham.net/articles/38211 On display in your Vanishing Texan Museum is a Vibroplex Telegraph Key. It is number 65,000 of over 300,000 that have been made and was used in the Jacksonville, TX train depot sometime in 1913. Although the key is over 100 years old it is in superior to excellent condition. We'll tell you more about Samuel Morse, the inventor of Morse Code, in a column next year. For now, let's start on May 4, 1844 when Morse transmitted the message "What Hath God Wrought?" from Washington D.C. to Baltimore, MD. This was the beginning of what many today call the "Victorian Internet." For the first time in history worldwide communications were possible at a speed never before imagined. The telegraph key that was to send Morse's message was invented earlier in 1844 by Alfred Vail, an associate of Morse, and was called the "Vail Correspondent." It was basically a switch with a knob mounted on a spring-loaded lever. The design evolved until a more reliable key (called the Triumph Key) was invented and patented by Jesse Bunnell in 1881. /////////////////////////////////////////// Australia Ends Major Shortwave Broadcasts: Posted: 10 Dec 2016 04:48 PM PST http://www.eham.net/articles/38210 Radio Australia will turn off its shortwave service to the Pacific and Papua New Guinea on January 31, in favour of more localised FM radio outlets and internet streaming. The independent international media organisation is part of the government-funded public Australian Broadcasting Corporation (ABC). The ABC International shortwave services will be replaced by a more robust FM transmitter network and an expanded content. While shortwave has served audiences well for many decades, it was now nearly a century old serving a very limited audience. /////////////////////////////////////////// Indonesian Earthquake Comms: Posted: 10 Dec 2016 12:21 PM PST http://www.eham.net/articles/38209 The earthquake in Indonesia on Wednesday struck at 5am local time.
