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 ...

[Tom Hall], along with many hams around the world, have been hacking the Silicon Labs Si5351 to create VFOs (variable frequency oscillators) to control receivers and transmitters. You can see the ...

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 ...

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 ...

The circuit was designed to create a frequency convert with the use of a crystal oscillator for the conversion of 10 MHz to 1 MHz. 7404 – a hex inverter utilizing TTL to achieve high speed at nominal ...

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 ...
