The 47-year-old Voyager 1 spacecraft is back in touch with NASA — but not out of the woods — after a technical issue caused a days-long communications blackout with the historic mission, which is ...

Starting Jan. 1, Posey County will track missing dementia and autism patients using wristband transmitters, which promise to ...

Cambridge Consultants are claiming the world’s first fully digital radio transmitter built only from computing power. There are no analog components like a high-speed D to A converter with amplifier, ...

Voyager 1 remains humanity's furthest outpost, hurtling across interstellar space at 38,210 miles per hour. However, NASA lost communication with the beloved space probe on October 19. The space ...

For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a ...

Ever since a young Henrich Hertz began constructing the scores of electrochemical cells needed to power the world’s first radio transmitter in the 1880s, designers have sought out better and more ...

Scientists have taken advantage of graphene's special properties -- its mechanical strength and electrical conduction -- and created a nano-mechanical system that can create FM signals, in effect the ...

Suppose you traveled back in time—say 40,000 years into the past—and then you got stuck. What would you do? How would you rebuild all the stuff that you like? That's the premise of the book How to ...

Across the observable universe, galaxies advertise themselves in radio waves for familiar reasons-magnetic fields, cosmic ...

A simple fm radio transmitter circuit which covers frequencies from 88 to 108 MHz. It is built with 3 transistors: BC109, BFR91A and BFR96S. It is quite stable and the output power is around 200 mW.
