The constant-bandwidth channel designation shall be the channel center frequency in kilohertz and the channel letter indicating deviation limit; for exapmle, 16A, indicating fc = 16 kHz, deviation limit of 2 kHz.

The indicated maximum frequency is based upon the maximum theoretical response taht can be obtained in a bandwidth between deviation limits specified for the channel. See discussion in appendix B for determining practical accuracy versus frequency response trade offs.

Prior to using a channel outside the enclosed area, the user should verify the availability of range assets to support the demodulation of the channel selected. Very limited sipport is availbale above 2 MHz.
