Ever since I started tinkering with Arduinos I’ve wanted to build a shortwave receiver using a Si5351 oscillator to tune the frequency. When I saw and built the Soldersmoke Direct Conversion receiver I immediately saw a chance to give it a try. While I've dabbled a lot with Arduinos, I have never used the Si5351.... Continue Reading →
