LQA Averaging
This option sets the method used to update an existing link quality value stored
in ALE processor memory when the new link quality value is worse than the
stored value.
The option can be set to either replace the old values with the new values or
replace the old values with different weighted averages of the old values and
new readings.
Averaging reduces the effect that one bad reading might otherwise have on a
perfect channel. If a new reading is better than an old value, the old value is
replaced by the reading. There are four different averaging formulas available:

LQA Decay Rate

stored in the link quality table within the ALE processor.
Switching the sounding off and setting a decay rate of two hours would result
in the recording of a perfect channel (100% channel quality) decaying to an
unusable channel (0% channel quality) over a period of two hours.
