The Channel List
136 Manpack Transceiver 2110 series Reference Manual
About channels
A channel is a frequency or pair of frequencies to which a name is given, such as
‘Channel 1’, ‘4500’ and ‘Headquarters’. You must enter the details of at least one
channel before you can make or receive a call. Channels are stored in the Channel List.
Settings in the Channel List
When you create a channel, you must enter:
• a name for the channel
• the receive and transmit frequencies of the channel, if applicable
• one or more modes to be used with the channel
Channel names
A channel name can consist of letters, numbers or a combination of both. Before you
name any channels, consider using group names to make navigation in the Channel List
easier (for more information see page 121, Grouping and ungrouping entries).
Frequencies
The receive and transmit frequencies may be any frequencies within the HF range.
However, the transmit frequencies can only be those allocated to you by the relevant
government authority in your country.
Spectral regulations may require the TxD option to be installed in the transceiver. In this
case, you cannot create channels with new transmit frequencies. You can, however,
create receive-only channels, and channels with the same transmit frequency as an
existing channel. If the TxP option is installed in the transceiver, you cannot create
channels.
Modes
A mode specifies a combination of a sideband (for example, USB or LSB) and IF filter
settings (that is, bandwidth and centre frequency). Each channel must have at least one
mode. You may want to select several modes for each channel depending on the modes
available to you.
When the standard IF filter is fitted, the allowable modes are USB and LSB. If a different
filter is fitted, other modes are available. For example, if you have a wide IF filter fitted,
USBW and LSBW are available (2110 only). If you have a narrow Morse filter fitted,
USB CW and LSB CW are available.
CAUTION
You should be aware of any restrictions placed on channel names in your
transceiver when it is used with a Codan HF data modem, radio/telephone
interconnect, or InterNav© software. See the documentation provided
with this equipment.
