| This was to be the final design. I made four of these, two of them for friends. Then I was asked by another friend to make him one and found that I could no longer obtain the instrument case. I also found it hard work making the LF coil (photo 4). Filing out the slots in the Perspex former was difficult. The HF coil (photo 5) was easy enough to make because I had a template for drilling the holes. But I had to find a new box and rethink the whole layout. Maximum power handling 100 watts. | |
