I spent a couple months memorizing the test questions/answers with Anki, without learning the theory, and passed the second level test (the one below Extra, I forget the name). I got a cheap Chinese (ABBREE brand I think) radio but never learned how to use it, and am a bit worried about accidentally transmitting if I poke around on it, even if it is probably legal for me to do so (assuming I announce my callsign periodically and such). I'd been meaning to learn things properly once the test was out of the way but I kinda lost interest, I guess. I'll still renew my license if it's about to expire anyway. Might as well. Callsign not shared because I tied it to my real address and haven't gotten a P.O. box (also as previously stated I am not actually active).
If you are interested, find and go to an amateur radio club meeting. The licensing test makes sure you know the regulations and some theory. It does not help introduce you to "ham culture" which is definitely a thing. I learned all the practical stuff from talking with local club members. They are usually overjoyed for new members; if not just go to the next club. Youtube and whatnot helps but it's better to be able to ask someone a stupid question, and believe me, if you want to be overwhelmed with information, ask a ham a question. In my experience there are some assholes but more genuinely kind people, mostly older folks who just want to connect with someone.
Interesting idea, thanks!
