The reasons why they were misunderstood have never been ascertained,
and there are several possibilities. It's not even clear how much was
understood or misunderstood, since a number of the people involved are
dead. The common point to all the possible scenarios is misunderstood
radio communication.

Because of a heterodyne, NOT poor radio transmission quality. As
someone else already pointed out, FM doesn't even have this useful quality.

And yes, the official probable cause lists the heterodyne. I thought
you would have known that, seeing as you know allegedly read all these
accident reports.

(And since one full flight crew survived, that's pretty good eyewitness
account)
