LBT Waveform
The LBT Waveform entry sets the type of waveform that LBT monitors.
If you want outgoing calls to monitor the channel for:
• voice calls, or any call to another station made using a Selcall or ALE/CALM
HF network, select Voice and calls
• voice calls, any call to another station made using a Selcall or ALE/CALM HF
network, or any calls made via a data modem, select Voice, calls and data
Default value: Voice and calls
Respond GPS
The Respond GPS entry sets the way in which the transceiver handles its response
to a Get Position call sent through an ALE/CALM or Selcall HF network.
If you want to:
• respond to a Get Position call regardless of the privacy mode of the HF network
through which the call was made, select Always respond
• respond in a proprietary Codan-encoded format to a Get Position call on an HF
network with the privacy mode set to Group or None, select To Codan
requests
• respond to a Get Position call from another Codan HF transceiver on an HF
network with the privacy mode set to Group and a common privacy key, select
To encrypted requests
• disable your response to any Get Position call, select Never respond
Default value: Always respond
NOTE: The To Codan requests value specifically excludes calls made
using an Open Selcall HF network, and calls made using an
ALE/CALM HF network with a privacy mode of Plain
(MIL-STD-188-141B ALE option).
NOTE: You are still able to make Send Position calls if this entry is set to
Never respond.
NOTE: To respond to Get Position calls made in an Open Selcall HF network,
the Respond GPS entry must be set to Always respond.
