Beacon Call
Beacon Call allows the operator to determine the signal quality between their
station and the station they want to call on a particular channel, but without
actually alerting the station they are doing so.
When a Beacon Call is sent to another station, and if the channel being used is
open, the remote station sends back a distinctive four-tone revertive signal. The
operator can judge the quality of the channel for communications purposes by
the strength and clarity of this distinctive tone. Using Beacon Calls on several
available channels will determine which channel is best to use for subsequent
Selcalls or Telcalls.
Note: both stations must be programmed for Selcall or
Telcall operation.
Sending a Beacon Call
1.
Listen for traffic on your selected channel.
If traffic is heard, select another channel
and try again.
2. Press
and, if necessary, press the
icon to show the Call Selection
screen.
3. Either:
• Select Beacon Call, enter a Selcall Id
manually and press Enter, or
• Choose a contact from the Contacts
icon
and then select Beacon
Call.
4. Wait for the Beacon Call to be sent and
listen for the distinctive four-tone rever-
tive signal from the station you have
called.
• If a revertive tone is not heard, or is dif-
ficult to hear, try another channel and
repeat the process until the revertive tone
is clear.
