Learn how to make a simple device for monitoring the state of the ionosphere and the quality of shortwave signals using the CA3089 chip. Shortwave Propagation is the way radio waves in the 3 to 30 MHz ...

Do you remember your first portable radio? For Sjef Verhoeven, it was a Sony Walkman in 1993. As is common in the Netherlands, he would often ride his bike. That spring, he heard FM stations from the ...

LILYGO T-Embed SI4732 is an ESP32-S3 development board with an AM/FM radio, a TFT display, a rotary encoder, a built-in microphone, and a microSD card slot powered through a USB-C port or LiPo battery ...

The monitoring of slopes’ dynamics is essential to ensure the safety of infrastructures exposed to landslide risk and to develop mitigation strategies. However, it is not always possible to perform ...

The QN8066 is a fun little FM transmitter chip. It covers the full FM broadcast band and has built-in DSP. You would find this sort of part in car cell phone adapters before every vehicle included ...

In this article, we will explore a straightforward method to create an IR remote-controlled FM radio with RDS (radio data system) using the ESP-01 module. We will utilise the Arduino IDE for software ...

This document is aimed at the Arduino developers, radio experimenters, hobbyists and anyone interested in building a receiver based on the Si473X IC family from Silicon Labs. This project is about an ...
