Yep. And ham radio is both an interesting hobby in its own right, and one place where you can build, experiment with, and learn about all sorts of electrical and electronic concepts. I can't recommend highly enough getting a Technician class ham license (the test is super easy with a little bit of study and only costs something like $15.00), a cheap dual band transceiver (I use a Baofeng HT), an RTL-SDR "dongle", and starting to explore the world of radio.
