Setup procedures—Part 1

5-10 HF SSB transceiver reference manual

Call Retry Limit (ALE option 13)

This ALE option controls the number of times the ALE

station tries to establish an ALE link using each channel in

turn from the scan group.

You can set 99 for no limit to the number of tries or a value

in the range 0–98.

On each selected channel, two attempts are made to establish

a link before trying the next preferred channel, where two

more attempts are made and so on, until all channels in the

scan table have been tried (unless a link is established).

The sequence is then repeated dependent upon the number

set in the Call Retry Limit.

If a link is not established, the display shows

LINK FAILED

accompanied by error beeps. Retry duration can be up to one

minute per channel.

Channel Quality Averaging (ALE option 14)

This ALE option sets the method used to update an existing

channel quality value stored in ALE controller memory

when the new channel quality reading is worse than the

stored value.

You can replace old values with:

• new readings

• different weighted averages of the old values and new

readings.

Averaging reduces the effect that one bad reading may have

on a perfect channel. If a new reading is better than an old

value, the old value is replaced by the new reading.
