Im currently doing my Undergrad in International Relations in Japan and I stumbled into this somehow somewhere I forgot but it seems interesting. Now I know that I have to have a license to operate and I'm looking to study and get my Technician license since its the a more versatile option for me in Japan. Do any of y'all have like study videos/lectures from somebody somewhere so that I could crosscheck with my Dan Romanchik book?
