The RT-9000 B operations described in this manual section cover the most basic and common operations.
Figure 7.3.2.1 RT-9000 B Basic Set Up Controls
7.3.2.1 TRANSCEIVER MODE, AGC, AND TRANSMIT POWER SET UP
These settings determine the basic operating characteristics for the Receiver and Transmitter sections of the
RT-9000 B Transceiver. These settings are Transceiver Emission Mode, Receiver AGC speed characteristic,
and Transmitter RF Power Output level.
Unless otherwise noted, refer to Figure 7.3.2.1 for the location of controls and features.
Transceiver Emission Mode Selection
To select the Emission Mode, depress ‘MODE’ key successively at 2 until the desired selection appears
in Operational Display segment at 3. This selection applies to both Receive and Transmit operation. The
choices are ‘USB’, ‘LSB’, ‘CW’, and ‘AM’. If the Data filter option has been installed in the RT-9000 B
Transceiver, a 'DATA' choice will also be displayed and be available.
Receiver AGC Speed Characteristic
To select the Receiver AGC speed characteristic, depress ‘AGC’ key successively at 4 until the desired
selection appears in the Operational Display segment at 5. The choices are ‘AGC-S’ (Slow), ‘AGC-
M’(Medium), and ‘AGC- F’(Fast). The ‘Slow’ AGC characteristic is generally desirable with speech
transmission. The Fast AGC characteristic is desirable for data transmission.
