We’ve seen tons of projects lately using the ESP32-C3, and for good reason. The microcontroller has a lot to offer, and the current crop of tiny dev boards sporting it make adding a lot of compute ...

This simple little circuit can be used for AM, FM, and Shortwave(SW). On the shortwave band this active antenna is comparable to a 20 to 30 foot wire antenna. It is further more designed to be used on ...

The use of directional arrays in FM broadcasting has increased greatly in 30 years. Especially in the NCE reserved band, a DA can increase the operating power of a station significantly while still ...

Antenova Ltd has announced the addition of the M10385 dual-mode receive/transmit internal surface mount FM Antenna Module for a broad range of mobile and digital media device applications. The company ...

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 ...

I often wonder if Major Armstrong knew what he was giving to the world when he began developing frequency modulation as a public service. Before World War Two, when the low-band FM service was a ...

[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 ...
