Making and receiving calls
2110 SSB Transceiver Reference Manual 167
In a Codan Selcall network, a Channel Test call sends a request to the station you want to
call on the channel/mode you have selected. The receiving station automatically returns
an audible test signal. The volume and clarity of this signal indicates the quality of the
channel/mode.
You can also test channels once you have started a call (for more information see
page 176, Replacing LQA information as part of a call in an ALE/CALM network and
page 174, Testing a channel as part of a call in a Codan Selcall network).
Emergency call
If you want to trigger an emergency alert tone at a particular station and speak to an
operator, make an Emergency call. If the GPS option is installed in the transceiver (and
you have connected and configured a GPS receiver), your GPS position is automatically
sent with the call. Emergency calls can be sent to several stations at once (see page 150,
Setting up the emergency key and page 170, Group calls in a Codan Selcall network).
If you have the FED-STD-1045 ALE/CALM option installed, you can use the ALL
address syntax with the Emergency call type to send a call to a group of stations using an
ALE/CALM network. If you have the MIL-STD-188-141B ALE option installed, you
can use the ALL, ANY, Group Selective, NET, and Wildcard address syntaxes with the
Emergency call type to send a call to a group of stations using an ALE/CALM network.
For more information on the ALE address syntaxes you can use with an Emergency call
see page 164, Summary of the special ALE address syntaxes.
Get Position call
If you want to obtain the GPS position of a station that has the GPS option installed in
the transceiver (and a GPS receiver connected to it and configured), make a Get Position
call. Get Position calls are automatically answered by the receiving station so an operator
is not required to take any action.
The information you receive from a Get Position call is displayed on the front panel as it
is received, if permitted, and is stored in the Calls In Log (see page 192, The Calls In
Log).
NOTE
You can use any of the characters in the basic 38 ASCII subset (A–Z, 0–9,
@ and ?) for the address.
NOTE
You cannot use the ALL, ANY, Group Selective, NET, or Wildcard
address syntax with a Get Position call.
NOTE
The success of your Get Position call will depend upon the setting in the
Cfg Respond GPS entry in the Control List of the transceiver you are
polling and the Privacy Mode of the network you are using for the call
(see page 204, Cfg Respond GPS).
