NVOY™ TRANSCEIVER REFERENCE MANUAL
ALE Call Scan
The ALE Call Scan entry sets whether or not your transceiver scans channels for
incoming calls between a call attempt on each channel.
If you want the transceiver to:
• make outgoing calls without any scanning cycles between call attempts, select
Disabled
• only scan the channels in the HF network through which the outgoing call is
being made, select Outgoing HF network
• scan all the channels in the HF networks that are set to be scanned, select
Scanned HF networks
Default value: Disabled
When this entry is set to Disabled, the normal ALE calling sequence is used, that is,
the transceiver attempts a call on the first channel in accordance with its settings for
LBT and number of retries, then tries the next channel, and so on until the call is
successful. The transceiver may miss incoming calls during this outgoing call activity.
When this entry is set to Outgoing HF networks or Scanned HF networks the
transceiver performs a scan cycle, then checks if the channel for the call attempt is
unoccupied, and if so, attempts the call. If the call is not successful, the transceiver
performs another scan cycle, then either retries the same channel (depending on the
value set in ALE Retries), or moves to the next channel.

ALE Scan Cycles
The ALE Scan Cycles entry sets the number of scan cycles that the transceiver
performs between call attempts when the ALE Call Scan entry is set to Outgoing
HF network or Scanned HF networks.
Range: 1 to 5
Default value: 1
ALE Call Threshold
The ALE Call Threshold entry sets the minimum score for a channel to be tried in
ALE calls.
When the quality of a channel is tested it is given an LQA score. This score is based
on the results of local and remote measurements for BER and SINAD, and on the call
weighting value set in the ALE Call Weighting entry.
NOTE: If the ALE LQA Exchange entry is set to Disabled, remote
measurements are not used.
