Let’s construct a low-power FM transmitter using surface-mount devices (SMD) that will be received with a standard FM radio. Soldering surface mounted devices is not so hard and actually is quite easy ...

This FM transmitter circuit uses four radio frequency stages: a VHF oscillator built around transistor BF494 (T1), a preamplifier built around transistor BF200 (T2), a driver built around transistor ...

The Si47xx series of integrated circuits from Silicon Labs is a fascinating series of consumer broadcast radio products, chips that apply SDR technologies to deliver a range of functions that were ...

Making your own FM radio is practically a rite of passage for hackers. How about making a small FM transmitter? Originally designed by the Japanese multimedia artist [Tetsuo Kogawa], this simple FM ...

Scientists have taken advantage of graphene's special properties -- its mechanical strength and electrical conduction -- and created a nano-mechanical system that can create FM signals, in effect the ...

Placing a sheet of atom-thin graphene into a feedback circuit causes spontaneous self-oscillation that can be tuned to create frequency-modulated (FM) signals. Changyao Chen, Sunwoo Lee, Columbia ...

A Handy Road Map for Your NAB Show Transmitter Trek The spring NAB Show in Las Vegas provides the best opportunity to get an up close look at all the high-dollar capital items you may need in the ...
