A PLL VFO/controller for a multi-band SSB/CW transceiver, targeting Arduino Nano and si5351. The script is SP_VFO_Controller.ino. An initialiser script must be executed once to initialise EEPROM. This ...

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 ...
