Discussions with FM engineers unearthed concerns about radio’s future when considered with reference to streaming, DAB/IBOC, RBDS, satellite radio, and new applications of some laws of electronics ...

Micrel Semiconductor has developed a single-chip radio transmitter for unlicensed bands in the 280 to 460MHz range that automatically corrects for differences in a connected loop antenna so the board ...

A simple fm radio transmitter circuit which covers frequencies from 88 to 108 MHz. It is built with 3 transistors: BC109, BFR91A and BFR96S. It is quite stable and the output power is around 200 mW.

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 ...

Bench-top model: the optical setup of the Grenoble analogue photonic correlator, which can be used to locate a radio transmitter. (Courtesy: Hugues Guillet de Chatellus/Université Grenoble Alpes-CNRS) ...

If a device connects wirelessly to other things, chances are high that it has an antenna in it. But as crucial as these components are, the rigid metals they're made of can limit what devices they can ...

The 47-year-old Voyager 1 spacecraft is back in touch with NASA — but not out of the woods — after a technical issue caused a days-long communications blackout with the historic mission, which is ...

Whether slalom or alpine skiing, competitive skiing is all about thousandths of a second. Hence, professional athletes must constantly refine their technique. Small radio transmitters will make it ...

We examined whether surgically-implanted radio transmitters with percutaneous antennas affected behavior of Lesser Canada Geese (Branta canadensis parvipes) in Anchorage, Alaska. We implanted either a ...
