Entries for a channel
Channel name
The channel name is a label, in any supported language, that is given to a frequency,
or pair of frequencies, that is used to receive and/or transmit HF radio signals.
A channel name can consist of letters, numbers, or a combination of both. A channel
has a name that uniquely identifies it, and makes it available for selection in other
areas of the user interface of the control point.
NOTE: If you are using a Dual Antenna Adaptor, you may like to include the
antenna selection for a channel into the name of the channel, for
example Ch 1 A1 and Ch 1 A2.
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.
Frequency
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 add channels with new transmit frequencies. You can, however,
add 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 add
channels.
