Description: circuit boards use state-of-the-art surface mount technology ... and longterm stability when exposed to severe ambient temperature variations. The transmitter features a watertight, ...

Most of us know these transmitters as the first radio systems, and from there we’ll probably also know that they were phased out when better circuits arrived, because of their wide bandwidth.

romantic about a circuit built around hot glass and metal. To wit, we present this compact two-tube “spy radio” transmitter. From the look around his shack — which we love, by the way ...

In 1912, he developed a feedback circuit, which would increase the output of a radio transmitter and produce alternating current. He didn't see the worth of his discovery, though, and by the time ...

John Bisset's Workbench gives you tips to prepare a wintertime visit to a transmitter building, from a plastic sled to a survival checklist.

Description: a diode in a DC circuit. A circulator adds a third port and is used primarily to isolate a transmitter and a receiver from a single port. At Dexter, we also offer the ability to calibrate ...

Voyager 1 is now using a radio transmitter it hasn’t relied on since 1981 to stay in contact with its team on Earth while ...
