Seriously, any ideas to slow the tuning rate will be most welcome .


Hi Lee,

Use the old stand-by of the screwdriver antennas, a screwdriver motor.

However, I expect you want two speed - then try a variable speed
battery powered drill.

For fine resolution and high speed both, look into the world of
Stepper motors. You can even design for calibrated settings instead
of hunting - or rough position indicators.
