First thing I designed was the new F-91W chassis
Obviously it took me a few tries to make the new chassis fit properly.
Well... maybe more than "a few".
This process was made way easier thanks to N-O-D-E sharing his project files.
Then, to make my life easier, I started printing a few instruments for building the antenna. The first thing I designed was a guide for the wire to be wrapped around.
Then I needed a loop antenna for my NanoVNA for the antenna matching stage.
