ALE Sounding call
NOTE: The ALE Sounding call type may be used if the MIL-STD-188-141B
ALE option is installed.
If you want to update the LQA information stored in other transceivers in your
communication network, make an ALE Sounding call. The sounding call is an ALE
broadcast call that is made on all channels in the scan tables allocated to the selected
HF network. A transceiver that detects the sounding call updates the information
stored in its LQA database.
Channel Test call
If you want to test the suitability of a channel/mode before you use it to transmit voice
or data, make a Channel Test call to a specific station.
A Channel Test call may be made in an ALE/CALM HF network if you have the
MIL-STD-188-141B ALE option installed. Information from this call replaces the
information stored in the LQA database for the called address using the same HF
network for the current time slot. The calling station automatically sends a beacon on
each channel/mode combination allocated to the ALE/CALM HF network, recording
local and remote BER and SINAD information, and calculating an LQA score. The
LQA screen is visible during the Channel Test call.
