[HBR] Balanced inductor antenna tuner

[Ralph Fowler]

Balanced inductor antenna tuner

Stepper motor controlled balanced inductor antenna tuner - incomplete but good project start. Good for parts and worked last time I worked on it few years ago. Built on a 1/8" panel.

Can't remember the connections to the stepper motors but there should be lots of info on Internet. And you will need to buy a stepper motor controller - kits available from several suppliers. There are also two 10 turn pots in the homebrew gear box to monitor position of the inductor and tuning cap.

$100 plus shipping. Email for picture.
