Gary, those were some useful links, thank you for the information.
It makes more sense now about FM, it has to have more precise control of frequncy (as that is how it controls servo movement) and can always operate at full amplitude, where AM will be operating at significantly lower amplitude for center, and thus be more susceptible to noise (same noise, less signal, lower SNR/more susceptibility.)
I think when you say shorter and stronger, you are more referring to the aspect ratio of the wave, in that the amplitude can be higher relative to the wavelength. I still don't see how the wavelength would change, however the aspect ratio difference between AM and FM is now obvious to me.
