Waht, After doing a little more research what you said made sense, about the input to the transistor causing FM modulation because changes in the transistors internal capacitance.
I am still having a hard time understanding what you are trying to explain here.
Waht and skeptic2 thank you...
I have been studying multiple AM and FM transmitter schematics trying to distinguish the differences in the circuit that create either am AM (amplitude modulated) or and FM (frequency modulated) RF signal. I have hit a road block as I am unable to see any significant differences between the two...
