This project implements a VFO and BFO using an Arduino with Si5351 signal generator. You can controll the VFO using an encoder and also a SmartPhone via a mobile application developed here for this ...

If you’re dealing with RF, you’ll probably have the need to generate a variety of clock signals. Fortunately, [Jason] has applied his knowledge to build a SI5351 library for the Arduino and a breakout ...

[Tom Hall], along with many hams around the world, have been hacking the Silicon Labs Si5351 to create VFOs (variable frequency oscillators) to control receivers and transmitters. You can see the ...
