We also recently were talking about hams experimenting with digital modes and this is a great example, both by the developers of FSQ and [jmilldrum] for implementing it with an Arduino.

The HamShield supports both voice and packet radio modes. You could even invent your own digital modes with enough skill. It is compact, lightweight, and works great with any Arduino or Arduino ...

Ever wanted to build an FM radio? Armed with an Arduino and a RDA5807M FM radio module, T. K. Hareendran shows us how to get started.

There are a lot of radio options in the U.S., but shortwave radio (SW) is a big deal globally. It's no surprise, then, that SW is going digital.

The Rapid Radio is a 2.4GHz ISM band devices and is both Raspberry Pi And Arduino compatible and is supplied with full rapidradio source ...

There was a time when radios actually had dials, but [glasslinger] is in a class all by himself. He’s adding a digital display to a 1940s radio, and he’s doing it with Nixie tubes.

Arduino Defined Arduino is described by its makers as “ an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software,” whatever that means.
