There are controls which can be just as nice to spin as any existing
tuning dial and can control a digital circuit.
What does the existing knob control, an air capacitor? That dial knob can
be connected to another type of control which can be read by the MCU to
control the Si570.
How would you move the dial pointer in such cases?
Why change that?
