Selecting the Link Mode
Description
1. Press 'Link Mode' softkey.
2. Select desired link mode from listbox.
3. Press 'ENT' to confirm the new selection.
Possible values:
• ANALOG VOICE/FF
• INTERNAL MODEM (option HF modem
required)
It might be needed to set the link mode of the
ALE more precisely in the configuration menus
of FF and HF modem. If for instance the mod-
ulation –J3E is needed for link setup and traf-
fic, go to ALE FF Config (page 1111) and
select it using the 'MODE' softkey.
The same applies for INTERNAL MODEM, set
the waveform in ALE HF Modem Configuration
menu (page 1521) and the data rate in ALE HF
Modem Operational menu (page 1511).
Some dependent parameters can only by
changed without an active link, so press
'Terminate' before changing them.
In contrast to ALE-3G, the ALE-2G does not
transfer the link mode over air. So please
make sure to use the same link mode settings
on all participants in your radio link.
