AM modulation is perfectly justified in this context: if two (or more) stations accidentally transmit at the same time, this will be noticed. Using FM, only the stronger signal wins and the other signal remains undetected. The advantage over digital transmission is the lack of coding overhead - the voice reaches the receiver without any time delay.
