Combined ALE / Selective Call Capability
Overview
The combined ALE / Selective Call capability allows the user to receive and
transmit ALE and Selcall type calls on channels which are programmed for ALE
scan but also have Selcall enabled on them. This means that during ALE channel
scanning the transceiver can accept incoming Selcalls. However, this feature can
only be used if the ALE scan rate is set to 2 channels per second (set in the
“2000 Series Programming Software”)
To Commence Scanning
Note:- You should have selected the required scan list before you commence
scanning, refer to the section “ALE scan list select” in the ALE protected menu.
Press the key
the PRC-2090 transceiver will now be ALE scanning and ready to
accept ALE calls, receive “Soundings” and transmit “Soundings”
(If “Sounding” is enabled on your transceiver)
The PRC-2090 transceiver will also be able to decode incoming
Selcalls as long as 2 channels per second is set as the ALE scan
rate and Selcall is enabled on the scan channels. Selcall
decoding is handled just like it is when the transceiver is in
standard non-ALE scan mode.
During ALE scanning the following messages may be displayed:-
This occurs when your station receives an ALE sounding from
another station in the network.
