I am using a geared motorised volume control motor
from an old stereo amplifier to remote drive the large ganged tuning capacitor
using an additional shaft geared reduction drive coupling device to slow down
the speed of turning the capacitor, choosing a lower voltage to drive the motor
with will also slow down the turning which will allow more accurate tuning or
peaking of the loop.
Once mine is finished then I will post photos of
all the important parts for all to see.
Best regards!

Very nice! Hey, I wonder if you could use a servo to tune the
loop
remotely. Or one of those surplus motor driven
potentiometers,
linked to the tuning cap shaft.
