Front Panel Display for 25 kHz and 8.33 kHz Channel Spacing
When setting the operating frequency of the radio and 8.33 kHz channel spacing is required, the
frequency that must be entered differs from the actual channel frequency. Table 3-1 shows the pattern
used for 25 kHz and 8.33 kHz spaced channel frequencies from 118.000 MHz to 118.141 MHz. The
pattern is the same for any frequency. The display conforms to ICAO convention for 8.33 kHz operation.
