Network Stations. The following supported calling methods are covered in detail later in this section.

Point-to-Point Calling
B) Sounding
C) NET CALL Calling
D) ALL CALL Calling
Before initiating any ALE call, the operator must confirm or select the following: 1.) operating frequency
Channel Group and 2.) the
Current Network ALE Network
Unless the operator is changing to new operating frequencies, the Channel Group selection used for ALE
Transmit operations will be the same Channel Group used for ALE Receive operation. No operator action will
be required.

key. The Feature Menu Display shown in Figure 7.3.4.6 will re-appear. Depress the ‘END’ key again.
