They also sold a lot of CB radios and walkie-talkies. I don't remember ham radios per se but it's not something I was ever really in to during the heyday of Radio Shack. I had a couple of their walkie-talkies as toys when I was a kid; they were just low-power CB channel 14 radios.

I still have a Radio Shack CB radio from the early 80s, works fine!
