Re: Continuing discussion on HT vs MM
Nice....
You can use an electric screwdriver to drive a threaded rod. A nut on the rod will move up or down the rod when the screwdriver motor runs.
You just take the bit out of the screwdriver and slip in the threaded rod. Drill a hole and insert a pin so the rod turns with the screwdriver motor.
I cut some plastic to the size and shape I needed and threaded a hole for the rod. (I used it for tuning an HF antenna.)
You might need to put the screwdriver in a box to keep the noise down.
