Call preamble length (option)
Setup code 242
This procedure sets the length of the preamble transmitted at
the start of a selcall or ALE call.
Before you can use this procedure, you need to enable the
selcall option (see Chapter 7, Password entry to enable
transceiver options).
To send an ALE call, your station needs to be set up with an
ALE controller.
The preamble is part of the coded selcall and ALE message
structure which is transmitted when you send a call. The
preamble allows the receiving station sufficient time to scan
to the selected channel and recognise the incoming call. ALE
calls need a longer preamble than selcalls.
You can set the preamble for:
• ‘
Selcall
’
• ‘
ALE
’.
The ‘
Selcall
’ preamble lasts six seconds. The ‘
ALE
’
preamble lasts 12 seconds.
To change the preamble length:
