Well, I am very well aware of the fact that building a high power tuner is DIFFICULT. It is a big project and it needs a lot of knowledge and expertise to make it and get it working properly. So, I do not build it from scratch. I want to use a kit that looks solid. I stumbled on the internet and found the kit of my dreams,.........the 1kW tuner, developed by Norbert Graupner, DL1SNG, back in 2010.

But,......there is quite a problem. You could buy the kit in the Funk Amateur shop, but it is sold out and will not be returning anymore,....so, what next ????

In the Funk Amateur papers, the schematics and the building principles were described, but building it by the schematics, is also a big job. So, I decided to contact Norbert,.......

I contacted him via the mail and he stated that his activities as a pcb developer stopped, but if I was interested in the details, he could mail me the documentation, in German 'Die Unterlagen'.

From this point, I want to thank Norbert very, very much, for this documentation, his kind answers on my questions, and his help to get it to work !!! Also, I want to thank Box73 for giving there consent to publish this documentation.

Without it, this project was impossible for me.

And, if there are amateurs out there, who want to build this tuner for them selves, feel free to contact me. I can help you getting it done.
