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 ...

This is an overview of a 500,000 Watt radio transmitter site. It’s one of the slides shared in a guided video tour of the transmitter’s hardware. The radio station — whose call sign was WLW — called ...

The familiar real estate adage “location, location, location” rings true these days for huge tracts on the outskirts of major cities — sites that for decades housed AM radio towers but that today ...

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 ...

Many of us tried the old “Two tin cans connected by a string” experiment as kids. [Michael Rainey, AA1TJ] never quite forgot it. Back in 2009, he built “El Silbo”, a ham radio transmitter powered ...

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 ...
