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