Dave Hughes is probably the premier technical and policy facilitator in grass-roots community networking. In 1981, he started what may be the first bulletin board system (BBS) whose goal was to empower the local public politically. Since then, Hughes has traveled around the world in an effort to bring some of the most disenfranchised and isolated communities into the electronic age. "I told my sons to bury me in a grave with space enough for an Internet connection so I can come back and keep giving 'em hell."
Entrenched interests tried to sue inventor of radio
by Andy Oram Dec. 12, 2001
This date marks a sterling moment in the history of technology: one hundred years ago, on December 12, 1901, Gugliemo Marconi became the first person to pick up radio signals transmitted across an ocean.
The triumph was quickly followed by one of the most ignominious acts in the history of technology: one of the most powerful firms in communications, the Anglo-American Telegraph Company, tried to stop Marconi from developing his innovation by threatening a lawsuit.
If you would like to see a remarkable US Patent filed by the 'the most beautiful woman in the world' of 1940, actress Hedy Lamarr.
The trophy wife of arms merchant Fritz Mandl, she entertained both the German and Italian general staffs as well as Hitler (she was Jewish), and Mussolini themselves. But by 1937 she was tired of being kept, so she drugged her maid and escaped through an open window. She wrangled a ride to the U.S.—and Hollywood—with Louis B. Mayer. There, she happened to meet composer George Antheil, who had written a piece for multiple player pianos. Sitting together at the keyboard, she realized that they were both playing the same piece only an octave apart, which gave her the idea of multiple radio frequencies broadcast one after another from a ship to a torpedo. With the help of an electrical engineer, the idea was patented. But the Navy passed on the idea as ludicrous, and the patent lapsed. Then in 1957, Sylvania Electronics took the idea and developed it for communications; the technology is the basis for all cellular phones today, GPS and is used in the Milstar defense communications satellite as well.

When Navajos Fought Japanese for Ne-He-Mah
By DAVID KAHN
It is the most romantic story in American cryptology. To keep the Japanese from getting American secrets in World War II, Navajos - among the original Americans - spoke over the radio in their native tongue.

VE3SUN DX Monitor Tools for the Intelligent DXer
Download the latest version
DX Monitor is a standalone Windows program which monitors the DX announcements available on the internet at DX Summit, HB9DRV and connections to one or more local and international DX Cluster Telnet Servers.
New DX spots are displayed in the main window with user selectable bands, fonts, colors, and highlighting of alerts and local spotters. A band map tracks the current stations on the air by frequency. Maps show the openings with buttons to select bands and times.
The predicted signal strength of the spotted station at your QTH can be displayed with each spot. A 24 hour propagation prediction by band takes only one click.
DX Monitor builds a database of DX Spots, Announcements, and WWV information and includes many tools which can be used by DXers to improve their chances of working a new country.
Experiments in airborne BASIC—"buzzing" computer code over FM radio
Before the 'Net, Finland created a primetime program-sharing radio service. A remarkable radio show that changed the landscape for him and a generation of Finnish technology lovers—a show that literally broadcast code over the airwaves. "If you wrote a piece of code in a computer, saved it on a [Commodore] C-cassette, took that cassette out and listened to it with an ordinary cassette recorder you heard sounds," Lehtonen explained. "But as sounds could be copied to another tape and as sounds could be transmitted over radio, then why should it not be possible to receive even these sounds of the code, record them with a C-cassette recorder and have the recorded sounds do their trick in another computer?" In other words—why couldn't you distribute code by simply playing it over the radio while enthusiasts taped it for later use?
