General and Historic Files & Documents

Most of the documents in this area can be viewed as Web pages. Others are files specifically to be downloaded. (Note: Most of these articles are on other organizations' servers. Please advise the LWCA Web editor if any of these links cease to work.)

This is one of several library areas under intermittent construction. Check for new files frequently.

Technology from the Past

• Arc Transmitters. Poulsen arcs were among the first practical undamped continuous-wave transmitters on LF. Ever wonder how they worked? Visit one of the newest articles in the LWCA libraries...the first of what may become several pages on Poulsen arc oscillators and related aspects of early radio history.

Historic Longwave Facilities and Personalities

• SAQ, Grimeton, Sweden Once a vital part of Trans-Atlantic communication, Grimeton now houses the last operable example of the Alexanderson alternator in the world. A unique Web tour of a unique museum.
• Ernst Alexanderson, inventor of the first practical method of generating high power undamped radio waves at LF, is profiled in this biography.
• Dr. Harold H. Beverage, inventor of the wave antenna that bears his name, was interviewed in 1968. This transcript, from the IEEE archives, covers several parts of Dr. Beverage's life, his work at GE and RCA in the early heyday of radio, and his encounters with other great figures of that era. In the interview and postscript, he recounts projects on frequencies from 15 kHz to 400 MHz...even the story of the first crystal-controlled radio transmitter.
• Jim Hawkins' NSS Naval Radio Transmitting Facilities Tour Page; photos and description of an actual tour of the facility.
• Guglielmo Marconi, more than you ever knew...or perhaps, wanted to know...about the man and his work. Directly from Italy.
• The 100th Anniversary of Marconi's first Transatlantic transmission is coming up in the year 2001, and the Society of Newfoundland Radio Amateurs prepare to commemorate the event.
• "The Distant Listener," a chapter from the Internet book Four Corners, by Dan K. Phillips, describes a literary journey to the Cape Cod site of Marconi's first wireless station in the U.S. Sketches the station's history, from site selection in 1901, through the first regular transatlantic service in 1903, reception of the Titanic's distress signals in 1912, to its dismantlement in 1920.
