Channels and modes
A channel is a name that is given to a frequency or a pair of
frequencies, for example, ‘Channel 1’, ‘4500’ and
‘Headquarters’. The frequencies may be any frequencies
within the HF range.
Each channel has one or more modes associated with it. Each
mode indicates a sideband that can be used with the channel,
such as USB or LSB. When you make a call you need to
specify the channel and the mode you want to use.
Table 4 shows examples of channels and the information
associated with them.
