Radio

Artist's concept of the Juno flyby (Image: NASA)

If you want to have a starship captain’s view of flying past the Earth, then NASA is happy to oblige. This week, the space agency released a video made of images taken by the Juno space probe as it shot past our planet last October. The unmanned spacecraft was using the Earth’s gravity to build up its velocity by over 8,800 mph (14,100 km/h) and slingshot it on its way to Jupiter. And as it did so, it took the time to receive a “Hi” from ham radio operators back home.  Read More

The development of graphene based nanoelectromechanical systems could lead to even slimmer...

A team of engineers from Columbia University has created a nano-mechanical system with the ability to create FM radio signals. In other words, they've built what is effectively the world’s smallest FM radio transmitter.  Read More

ScanEagles can provide real time telemetry for prolonged periods (Image: Boeing)

Radio has come a long way since Marconi bashed a telegraph key and radar is a miracle compared to when it was just a squiggle on a cathode tube, but despite a century of advances, they’re still prone to the same problems as the first pioneers encountered. For five days in July, the Office of Naval Research’s (ONR) Research Vessel (R/V) Knorr made a survey in the waters off Virginia Beach, Virginia using ScanEagle UAVs to study the effect of oceanic and atmospheric changes on radar and radio waves with the aim of producing more secure military communications and improve the ability of radar to detect hostile craft.  Read More

HAARP operational site on the edge of Denali State Park northeast of Anchorage, Alaska (Ph...

Reports that the High Frequency Active Auroral Research Program (HAARP) had been shut down permanently were apparently a bit premature. According to HAARP program manager James Keeney, the facility is only temporarily off the air while operating contractors are changed. So why does anyone care? Despite being associated with various natural disasters over the past two decades by the conspiracy fringe, HAARP is in reality a facility for studying the ionosphere. Let's take a look at the goings on at HAARP – past, present, and future.  Read More

Radio plays can transport listeners to far away exotic settings but the BBC’s prototype Perceptive Radio aims to give listeners a more localized experience. Shown to the public recently at the Thinking Digital Conference in Gateshead, UK, the Perceptive Radio uses local data and onboard sensors to adjust itself and even alter the script of a radio play in real time to reflect local conditions. The goal is to make listening to the radio more like attending live theater.  Read More

The Rukus XL unveiled at CES 2013 joins Eton's Rukus line

At CES Unveiled, we had the chance to sit down with Etón, a company that builds products for entertainment and safety that can rely on hand cranks or solar power to keep them running. In addition to the FRX series and the Rukus and Rukus Solar it was also spruiking at last year's show, the company is displaying its new ZoneGuard series alongside a couple of additions to its Rukus line and the new BoostSolar Mobile Charging Solution.  Read More

Plugg was created by Norwegian design duo Theo Tveterås and Lars Marcus Vedeler (Photo: Sk...

Radio receivers have changed greatly since the first units became widespread in homes at the beginning of the previous century. However, throughout each iteration, switching a radio on has usually entailed pressing a physical button. Plugg takes a different approach, employing a cork plug as a method of switching on or off.  Read More

The MIT metamaterial lens

We expect the world to be predictable. Water flows downhill, fire burns and lenses bend light in a particular way. That worldview took a jolt as Isaac Ehrenberg, an MIT graduate student in mechanical engineering, developed a three-dimensional, lightweight metamaterial lens that focuses radio waves with extreme precision. That may not seem too disturbing, but the lens is concave and works in exactly the opposite manner of how such a lens should.  Read More

The Spotify Android app banner on Google Play uses the radio feature as a key selling poin...

The Spotify app for mobile devices is free, but to get any usability from it beyond the trial period it requires the paying of a monthly subscription fee. While those using the desktop app can make do with adverts and playback limitations, there is no other option for mobile users besides paying the aforementioned fee. However, one feature of the Spotify app has been made available to U.S. users completely free, with the radio function now available to both iOS and Android users.  Read More

The electromagnetic compatibility of vehicle components is measured in a Fraunhofer lab

While electric cars are often touted as being less mechanically complex than their internal combustion-engined counterparts, there is at least one way in which they’re considerably more “involved” – their radios. Because electrical signals emitted by the car can potentially interfere with incoming radio signals, manufacturers must do things such as insulating the motor and shielding the cables. This adds time and material expenses to the production process. Now, however, researchers from Germany’s Fraunhofer Institute for Reliability and Microintegration have developed technology to help minimize the problem.  Read More
