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.

One of the easiest, simplest ways to make an FM transmitter is to buy this kit from BuildCircuit. It’s amateur friendly, so anyone should be able to use it. What you need for assembling this ...

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 ...

Here is a simple USB FM transmitter that could be used to play audio files from an MP3 player or computer on a standard VHF FM radio by connecting it to an USB port. The circuit use no coils that have ...

[Dino] got his hands on an FM transmitter “bug” kit via a friend, and thought it would make for an easy and fun Hack a Week project. The kit is simple two transistor half-wave FM transmitter, which ...

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 ...

Smallest FM radio transmitter just created using graphene by the wizards at Columbia University. This one is pretty cool and I certainly do not want to butcher the idea and explanation behind it all.

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 ...

This week Radio World is featuring highlights of our 2021 ebooks. This article appeared in “Mission-Critical: Maintaining Your Transmitter Site.” One hundred years is an impressive lifespan not just ...

A team of engineers from Columbia University has created a nano-mechanical system with the ability to create FM radio signals. In other words, they've built what is effectively the world’s smallest FM ...
