RT-9000 B
Channel Groups are formed simply by setting up the appropriate Pre-set Channel frequencies into the RT-
9000 B ’s memory using the procedures described in section 7.3.2.9. However, the Channel numbering in
these groups must comply with organization described in this section. ALE systems require at least two (2) or
more frequencies for effective operation.
If ten (10) or fewer frequencies are available, they would normally all be set up in the same Channel Group
(usually Group 0). If more than ten (10) frequencies are available, they could be arranged in groups with
some meaningful order and grouping. For example, ‘Daytime’ frequencies could be stored in Group 0 and
‘Nighttime’ frequencies in Group 1.
NOTE : Remember, ALE operation and scanning can use only one (1) Channel
Group at a time.
7.3.4.2.2 ESTABLISHING ALE-IDs
The RT-9000 B ALE Subsystem is capable of operating with multiple ALE Networks. The ALE system can
support a Network structure of up to twenty (20) separate ALE Networks. Each Network may contain a station
SELF ID for the RT-9000 B Transceiver plus station “CALL IDs” for up to nine (9) other Network stations.
When entering ALE IDs into the RT-9000 B , the user must follow a prescribed order to avoid confusion and
ensure correct entry.
Section 7.3.4.2.2 is divided into four (4) parts and describes entry of four (4) different types of ALE ID
information into the RT-9000 B ’s memory. When establishing a new ALE Network, the order of entry of this
ALE ID information will be as follows:
1. Establish and Enter Network ID (NET ID) Name
2. Select and Enter (SELF ID) Time Slot Position
3. Enter SELF ID Name
4. Enter Network Station CALL IDs (Time Slot Position and Name)
Additionally, this same sequence of operations must be repeated for EACH separate ALE Network (including
SELF & CALL ID entries). If the User will be using more than one Network, all entry steps should be
completed for the Network-at-hand before proceeding to and setting up the next Network.
While the steps in this section are primarily used to establish ALE Networks and enter ALE ID information, the
Network ID (NET ID) and CALL ID entry steps are also used as Selection steps for certain ALE operating
functions described later. The procedures used for both entry and Selection and are flagged when they occur
during the appropriate ALE operations.
NOTE: In the remainder of the ALE sections of this manual, ‘TUNING’ knob,
TUNING’ control and DIAL, all refer to the RT-9000 B front panel
“TUNING” knob.
