It's always entertaining reading all us old guys telling how to get young people interested in amateur radio, as if any of us really know what young people are thinking. I don't know how it was for anyone else but back in the day (around 1970 in my case) nobody had to "recruit" me or "elmer" me. It probably would have creeped me out and turned me off on the whole thing if they had. Kids can think for themselves. A lot of them are way smarter than any of us. If they're not developing an interest on their own, then nothing you do, no matter how simple the tests, no matter how hard you try to "recruit" and "elmer", it's not going to happen. Accept that and move on. Contrary to apparently most people, my opinion that amateur radio's future does not revolve around dragging kids into a hobby they are not finding on their own. But if it does, it does. So what.
