ATU-100 (N7DDC) Antenna tuner kit

Bought a nice kit (ebay / Ali, etc) to build an automatic antenna tuner (design N7DDC) which can handle approx 100 watts.
Tuner is usable from 160 meter till 6 meter.
It has a small but very clear oled display that shows all information you need.
For 30 euro i had the smd presoldered version, so the only thing you need to do is wind the coils and solder some normal components on the board.

Complete kit, very well packed in a plastic box.
PCB with all smd components already soldered.
You have to wind the coils yourself
Tuner finished! Next step is a nice enclosure
