FCC Rules and Regulations Part 2.202: Necessary Bandwidth and Emission Bandwidth
Voice -FM Analog (12.5KHz)


Max modulation (M) in kHz : 3.0
Max deviation(D) in kHz:2.5
Constant factor (K): 1(assumed)

Bn= 2XM +2XDK=11.0 KHz
Emission designator: 11K0F3E
9600 Digital Vioce/date (12.5KHz)


Data rate in bps(R)=9600

Deviation Peak deviation of carrier(D)=2359.585

Constant factor (K): 1 (default)

Bn= 3.86D+1.27RK= 3.86(2359.585)+0.27(9600)(1)=11.7KHz
Emission designator: 11K0FXD
