7.3.4.3.3 ALE Transmit Operation
The RT-9000 B ALE system supports four (4) different ALE calling methods used to communicate with other
Network Stations. The following supported calling methods are covered in detail later in this section.
A) 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.
Confirmation or selection of the correct ALE Current Network is absolutely essential for proper ALE system
function. Perform the following steps to confirm or change the ALE Current Network.
1. Navigate to the RT-9000 B front panel display shown in Figure 7.3.4.5.
2. Depress the ‘ALE-ID’ key. The Feature Menu Display shown in Figure 7.3.4.6 will appear.
3. Depress the ‘NET-ID’ key. The Feature Menu Display will change to that shown in Figure 7.3.4.8 as
described in the beginning of the paragraph dealing with Network ID Entry. Inspect the appropriate
area of the Operational Display and note the Network Number and Name when it first appears.
4. If the indicated Network (which is the Current Network) IS
the desired Network, depress the ‘END’
key. The Feature Menu Display shown in Figure 7.3.4.6 will re-appear. Depress the ‘END’ key again.
The RT-9000 B front panel display shown in Figure 7.3.4.5 will reappear. The user may continue
operations and skip steps 5, 6 and 7.
