8.33 kHz CHANNEL OPERATION
69 The 3000DV2 VHF, or V/UHF, radios can operate between 118.000 MHz and 136.975 MHz using
8.33 kHz channel spacing. When setting a radio’s operating frequency to operate with 8.33 kHz channel
spacing, a special frequency designation should be entered from the front panel, not the actual
frequency.
70 Table 4-1 shows the special frequency pattern over the frequency range 118.0000 MHz to
118.1916 MHz. These channel designations have been defined by ICAO and are detailed in
ICAO Annex 10, Volume v, Chapter 4. The frequency designation pattern is repeated over the available
8.33 kHz frequency range (that is, up to 136.975 MHz). Examples for entering frequencies are given on
the next pages.
71 When 8.33 kHz channel spacing is used, the radio automatically selects AM and narrow-band
working. Other modes are not available with this channel spacing.
