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. |
