Well you would have had only a few flyers and probably no club, because only a few would be able to use the ham band. And I am thinking the AMA had some input on the ham band as well.
We can speculate all day about 'what if' AMAhad not got our frequencies. Would model aviation have died out? Idoubt that. If that frequency allocation didn't exist, there would have been a vaccum for folks that are entirely dependent on them. As they say, nature abhors a vacuum.
