I have several different versions of boards that I have tried, but prefer the small module from Adafruit. Its been some time I have been wanting to use a SI5351 chip to build a VFO. A few days ago, RC (KE6BGN) commented that he was wondering if any progress had been made on the Arduino based VFO/BFO for the BITX40. I mentioned to my friend Gary N6SER how cool it would be to write some code for the Arduino to control the Si5351 via the standard Computer Aided Transceiver (CAT) control. Adafruit provides a program called 'Clockbuilder'. Code that works in aurduino ide compiles fine but there is no output from the module. Ensure that the voltage input is 3. So I decided to use the ADF4351 chip to design a VFO and see how it works. It can output up to eight unique frequencies at 8 kHz to 133 MHz. The main thing is, remove the old library before installing a new one. It will allow you to control the Si5351 with an Arduino, and without depending on the proprietary ClockBuilder software from Silicon Labs.
