Spiral coil germa radio

I will try to create a screw coil Germa radio, which is published in Seibundo Shinkosha's ``Comprehensive Guide to Making Germa Radio.''
I haven't tried making one for a long time because I thought it would be difficult to make and needed a variety of materials, but this time I decided to take the plunge and try making it.
It took a while as expected, but I managed to complete it.
It wasn't detailed in the book, so I wrote out the circuit diagram and various dimensions based on my own experience. It's in the second half of the video.
