I meant measure the actual FM from your crystal oscillator.
 
I wonder if the crystal's Q limits modulation bandwidth somehow.
 
 
 

Sure it does.  You can only move the frequency a small amount.  FM and
PM is usually generated at 8 to 12 MHz and multiplied up to 50 to 450
MHz.
This is for the old crystal controled  ham and pulic servce radios.
