Making a Channel Test call
A Channel Test call enables you to test the quality of a channel/mode in a Codan
Selcall HF network, and is sometimes referred to as a Beacon call. If you have the
MIL-STD-188-141B ALE option installed, a Channel Test call may be made in an
ALE/CALM HF network to replace information in the LQA database, and to perform
a manual sounding operation.
There are two ways to test the quality of a channel/mode in a Codan Selcall HF
network. You can test the channel before you make the call, or you can start to make
the call and then test the channel prior to connecting.
Making a Channel Test call in a Selcall HF network
If you want to test the suitability of a channel/mode before you use it to transmit voice
or data, make a Channel Test call to a specific station. The quality is determined by
the strength and clarity of a revertive signal.
