I’ve mentioned this on another sibling comment, but amateur radio is where you need to look. It took me about 6 months of casual study to go through all three license classes (tech took me like 2 weeks), and you learn quite a bit about everything you’ve mentioned in the process. More than that, you gain a license which allows you to legally experiment with this stuff.
