Portland, Ore. — Researchers at Cornell University have created the world's smallest mechanical oscillator that is capable of being tuned electrically. The nanoelectromechanical system (NEMS), which ...

In the ham radio trade, gear such as the old Drake units [Dr. Scott M. Baker] has in his radio shack are often referred to as “boat anchors.” It refers to big, heavy radios that were perhaps a bit ...

Amateur radio is the only hobby that offers its licensed operators the chance to legally design, build, and operate high power radio transceivers connected to unlimited antenna arrays for the purpose ...

Higher frequencies and low jitter are being prominently featured on the list of oscillator criteria for designers. In addition, low cost and quick delivery are top criteria of buyers. Having timely ...

IN this method the frequency of a radio-frequency oscillator is modulated by a sinusoidal audio-frequency voltage, and the resultant radio-frequency voltage is applied to a transmitting quartz ...

Of all the low-frequency oscillator configurations, the Wien Bridge has to be the friendliest and easiest to get along with. Like a faithful dog, it behaves itself regardless of the weather, is not ...

THE resistance-capacity tuned oscillator is well known as a very good generator of audio-frequency oscillations. In a recent communication by Rakshit and Bhattacharyya 1 it was pointed out that the ...
