I had decided to build one for portable use (plan is to be used on hiking, but also in my car) powered from Lithium Ion battery and with all components on 3. ATTENZIONE E' D'OBBLIGO UN FILTRO PER LA BANDA. Never hunt around for another crystal again, with the Si5351A clock generator breakout from Adafruit! This chip has a precision 25MHz crystal reference and internal PLL and dividers so it can generate just about any frequency, from <8KHz up to 150+ MHz. A simple and stable vfo is an integral part for radio experiments. To use this library, open the Library Manager in the Arduino IDE and install it from there.
