Retro mediumwave detector-radio by db3jhf
by Thingiverse
Last crawled date: 3 years ago
Old school detector radio technology meets 21st century 3d-printing. This is a simple to build and use detector radio for the mediumwave band. And yes - it runs without batteries (by only using the transmitted radio energy).
We developed this project for a kids day at our ham radio club. It is fun to build and to use - no matter if you're 9 or 99 years of age!
For most of the most popular stations in Europe you'll need about 28 turns which gives an impedance of 50 - 180 uH. Frequency range is about between 550kHz and 1100kHz.
