FM deviation measurement

Using a 2kHz tone it is possible to see the carrier dip with a deviation of 2.4, 5.52 and 8.66 times the 2kHz tone.

Using a 2M transmitter, a 2kHz tone and a deviation of 5kHz you get the sharp dip at the carrier frequency

Using a deviation of 11kHz you get the next bessel zero
