Actually,

The VX-7 has regular AM with about 60% modulation, on TX and I am not sure 
about the way they detect the audio but dosen't sound too bad on RX.
It is not High level modulation, my guess from what I had I would say they 
modulate one of the early stages of the TX. I would also guess there may be 
some FM in the signal.
I had one and can say it was fun, neat little radio.
