Well, first off, there ARE crystal versions of both the Delta and 
Phoenix. I don't know if they're FM or PM. Just FYI...

Because the others are synthesized, I more believe they are FM. And to 
add to that, they are all DCG (DCS/DPL) capable, and that *requires* 
direct FM of at least that part of the modulation.

Also you'd be hard pressed to find very many PM radios made in the last 
15 years or so. The MLS and MVS are less than 20.
