76 NGT ASR Transceiver Getting Started Guide
Networks and scanning
A network is two or more stations that use the same
frequencies and call system to communicate.
The frequencies are allocated by a government authority and
enable the network to maintain HF communication throughout
the day and night.
The call system is the method the network uses to make and
receive calls. For example, in networks that use the
ALE/CALM call system, the transceiver selects the best
channel/mode for the call.
The transceiver can be set to scan the channel/modes used by
your network to detect incoming calls. It is recommended that
when you are not using the transceiver to communicate you
switch scanning on. This ensures that you can receive calls
from stations in your network.
The CALM option
The NGT ASR transceiver has the CALM option installed as
standard. CALM stands for Codan Automated Link
Management.
The CALM option enables the transceiver to test the signal
propagation qualities of your channels and build a profile of
each channel’s suitability for use at different times of the day
and night. The transceiver can then select the most suitable
channel/mode for you when you make a call. You are able to
make ALE ALL calls with this option.
CALM is compatible with FED-STD-1045 ALE.
