How to calibrate the SI5351 oscillator crystal without expensive instruments
In radiofrequency, precisely adjusting an oscillator without tools like oscilloscopes or frequency counters can be a challenge. However, together with EB1A, we discovered that it’s possible to achieve an accurate calibration of the SI5351 module using a simple JavaScript calculation tool, ideal for DIY projects like WSPR. Project goal We want the oscillator to be as close as possible to the desired frequency (in this case, 14 MHz). We’ll use a calibrated receiver, such as…
