Another simple device to build on our list of easiest simple FM transmitters to make at home is this iPod FM transmitter. To build it, you need to form the coil first using a solid copper wire.

The FM transmitter circuit itself is based off one of [Art Swan]’s builds, but instead of the solderless breadboard construction you would expect to find in a small demo circuit, [Angelo] went ...

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.

To wit, we present this compact two-tube “spy radio” transmitter. From the look around his shack — which we love, by the way — [Helge Fykse (LA6NCA)] really has a thing for old technology.

The Streambot Y is a simple yet effective FM transmitter for owners of older cars, but the lack of automatic tuning could be an issue in areas with crowded airwaves.

This simple circuit measures the strength of a radiated signal from a transmitter. It is commonly used by model airplane builders to check whether their transmitter are really transmitting the radio ...

Over long cable runs, an isolated 4-to-20-mA current loop offers robust noise immunity and tolerance. This characteristic makes it popular for analog data transmission in noisy ...

FM Radio Transmitter (Version A) To build this simple radio transmitter, you will need to gather the parts such as a 9V battery, a clip, wires, a prototype board, a trimmer capacitor, a resistor ...
