Actually, in the hobby activities in the USA, amateur radio is NOT
very high on the list. That's reality, despite all the self-interest of
the very ardent ham fanatics.


It's roughly comparable to other hobby activities like
amateur astronomy, model railroading, model airplanes, and such.
Model railroaders and amateur astronomers, as well as
ham, are concerned about low numbers of younger people
getting into their activities. And these other activities
don't need a license.
