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.

If you need to generate a radio frequency electrical signal, you will make some form of electronic oscillator. We’ll probably all be used to oscillators using transistors, tubes, logic gates or a host ...

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 ...

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 ...

BAINBRIDGE ISLAND – A Washington-based subsidiary of Salem Media Group plans to add a new AM radio transmitter to its broadcasting site near Murden Cove and a residential neighborhood on Bainbridge ...
