Not at all. Part of the game. At least a thousand. Maybe. There was no requirement of actually operating back when I got my Extra, except to renew a license. In fact, "back then", someone could walk into an FCC office, pass all the tests for Advanced, toss the Advanced in a drawer for two years, go back to the FCC office and pass the Extra tests, and get an Extra without ever having been on the air at all. I don't know anyone who did that, but it was possible. And a few years after I got my Extra, it became possible to go from no license to Extra in one exam session. What changed things was the repeater boom of the 1970s-80s, which caused most new hams to start out on VHF/UHF rather than HF.
