SECTION 7.I
GENERAL INFORMATION
7.1.1 PURPOSE OF EQUIPMENT
The RT-9000 B is a 125 Watt HF/SSB Digital Transceiver that provides communications from 1.6 to 29.99999
MHz (receive 100 kHz to 29.99999 MHz). Modes of operation include USB, LSB, AM equivalent, CW, and
DATA (with external modems). The RT-9000 B is designed to be used in fixed station or mobile environments
and may be computer or remotely controlled using RS232, RS422, or FSK tones communications formats.
7.1.2 GENERAL DESCRIPTION
The RT-9000 B can be used in base station 19-inch equipment rack installations, on tabletops, in mobile
installations or transportable cases. Its rugged package makes the RT-9000 B ideal for all environments.
Internally, the RT-9000 B is designed with the service technician in mind. The Built-In-Test-Equipment (BITE)
capability provides descriptive front panel readouts about the operating status of modularized plug-in
assemblies. LED indicators located on the each module permits helps the technician rapidly identify a faulty
module.
The RT-9000 B has a simple, easily understood front panel. First time users may operate the RT-9000 B
without extensive training. A large LCD display provides continuous status of major operating parameters
such as Operating Frequency, Channel, Emission Mode, Power Output, Local/Remote control status and
Receiver AGC and BFO settings. Extensive metering functions allow the operator to monitor Transmit
functions such as Forward and Reverse power, ALC action, and Line Audio input levels and Receive
functions such as Signal Strength and Line Audio Output Levels. Metering is displayed as a bar graph.
Internal test routines handle and display easily understood status messages about external equipment, when
present, such as a Linear Power Amplifier and/or Antenna Coupler.
The front panel contains two (2) keypads. A function-oriented keypad provides ready access to basic
operating functions such as mode and setup selection. A numeric keypad provides convenient entry of
channel numbers, operating frequencies, and other numeric data. In addition to the Main Display and
keypads, a set of five (5) variable function keys with a dedicated display, together comprises an effective
system of additional operating controls. The set of function keys and its display are referred to as “Feature
Keys” and “Feature Menu”, respectively. The RT-9000 B ’s Feature Key And Menu system offers a flexible
means of presenting the operator with additional control and feature selections and is under software control.
This arrangement also permits context related feature choices and eases new feature implementation.
Gray is the standard color. If a particular color other than Gray is required, contact the Sunair Marketing
Department for information about changes to the standard color.
