a)
For some services, only the uplink frequencies are included.
b)
The carrier shall be modulated using a 50% duty cycle square wave signal.
c)
As an alternative to FM modulation, 50% pulse modulation at 18 Hz may be used because while it
does not represent actual modulation, it would be worst case.
