SI5351-B DDS VFO Radio Controller Prototype (An Overview)

This is the first part of a series of videos looking at a SI5351 based DDS VFO board that I am currently developing. The board is designed to take control of the local oscillators in old two way radio equipment. The unit allows fine tuning of LO's, FM modulation and can also produce CTCSS tones. This can be connected directly to a PC and programmed using the Arduino IDE via the on board USB type C port.
