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.

Tried that, it has far to much torque even on low volts .... damaged the
gearing on my spare cap :-/

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

Good idea, worth looking into!!

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.

I`ll do a google for steppermotors .... thanks.
