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.
The ALE Call Threshold entry enables you to set:
• the minimum score a channel must achieve for it to be tried in ALE calls
• the minimum acceptable standard for the channel at the time when a link is
being established
Generally, a score of 15% indicates a channel that an experienced radio operator can
use. A score of 25% indicates the minimum acceptable standard for voice
communication. A score of 50% indicates a good voice channel. A score of 80%
provides a very good voice channel.
The transceiver attempts to make calls on channels for which there is no score, but
only after channels with a score above the threshold have been tried. If there are no
channels that meet the ALE call threshold, the call is retried on the channels that
provided the best response during the first attempt.
Range: 0 to 100
Default value: 25
