How to Build and Code an Arduino VFO Si5351 PART-2

In this series of videos I go though how to build a VFO based on the Arduino platform using the SI5351. The VFO includes IF offsets, frequency displays and a high speed rotary encoder. The VFO can be used for making home brew radio projects, tuning many types of radio equipment including SDR receivers. This VFO has good performance and is relatively cheap to build. No programming skills are required and I will supply the code for the project and go through how to configure and upload it. In the video I go through how the circuits work and cover troubleshooting to get the VFO working. Part 2 In this video we cover the breadboard layout, trouble shooting, downloading the Arduino IDE and uploading the code. Downloads VFO Schematic Download https://drive.google.com/file/d/17vSC...
