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 ...

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 ...

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 ...

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 ...

The 185-foot masts and flattop antenna dwarf the transmitter building at the “new” 1931 WHK transmitting plant. Ever since Marconi began playing with radio at his family villa, there have been many ...

Half the population of Syria has been displaced. Hundreds of thousands have died in the conflict and millions are fleeing. For those who remain in the country, critical infrastructure is unstable and ...

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.

The heart of every radio transmitter is a reliable oscillator. Creating small, and tunable, oscillators that can maintain a precise frequency when conditions like temperature, pressure or humidity ...
