Remote Controlled Z-Match Tuner

A few years ago I have built a Z-Match tuner for QRO. I like antennas fed with open feeder and the priceless advantage
of low less in the feeding line. But the disadvantage lays in the challenge to lead the feeder through the wall into the

That was the reason why I thought about a remote controlled tuner. The tuner should sit out of the house. The feeder
ends at the tuner. A coax cable and a control cable leads through the wall into the shack. The controller in the shack is
used to control the capacitors in the tuner. There were several solutions found on the internet. Unfortunately none met
my requirements. While I was experimenting with the Arduino I decided to use an Arduino Clone to control the tuner.

The hardware simply consists of two servo motors to control the capacitors of the Z-Match tuner. For the controller a
shield was developed. There are connectors for a Wattuino Pro Mini and for the parts (rotary encoder, potentiometer,
LCD-Display, SWR-Bridge etc.)
