Default Why don't voice radio communications use FM?

Yeah, Steve, it would. But I think we might be able to swap (on a long term
swap basis) the VHF com band for stuff up between 600 and 900 MHz. that have
very limited usage. Not only could we get way more bandwidth, but the
antenna size is cut by a factor of 6 or so.

Perhaps this is a naive question, but: Why don't voice radio
communications for aviation use FM radio instead of AM radio?


Wouldn't that reduce the available frequencies?
