RT-9000 B
Completing the “Half-Duplex Operation” process prepares the RT-9000 B Transceiver to
Transmit and Receive using
DIFFERENT Operating Frequencies (but not
simultaneously) for the currently selected Pre-set Channel.
NOTE:
The Transmit frequency for currently selected Pre-set Channel may be
viewed by depressing the Read Transmit (‘READ XMT’) key at 13 . The
stored Transmit frequency will be displayed for about three (3) seconds
before reverting back displaying the stored Receive frequency.
If this type of operation is desired and the required Operating Frequencies have been entered for the
currently selected Pre-set Channel, proceed now to the next Heading. Continue entering or
modifying the required Pre-set Channel settings.
7.3.2.9.3 Transceiver Emission Mode Entry
Depress the ‘MODE’ key at 14 successively until the desired Emission Mode appears on the
Operational Display at 15 . The displayed Mode indicates the current RT-9000 B Emission Mode
selection. Four (4) choices are available: ‘USB’, ‘LSB’, ‘CW’, or ‘AM’. Depress the Enter (‘ENTR’) key at
6 to store this selection into the currently selected Pre-set Channel .
NOTE: A fifth Mode choice, 'DATA', will be displayed only if the optional Data
filter is installed in the RT-9000 B Transceiver. The RT-9000 B
Transceiver CPU Software DIP switch settings must also be properly
set for this option. (Refer to Section V of this Operation and
Maintenance Manual).
NOTE:
When Continuous Wave (‘CW’) Emission Mode is selected, CW Key
Release Time and Filter settings automatically default to ‘Medium’ and
‘Normal’ settings, respectively. Other choices are available and are
covered later in section 7.3.3.10 of this manual.
After the desired Emission Mode setting has been entered for the currently selected Pre-set Channel,
proceed to the next Heading. Continue entering or modifying the required Pre-set Channel settings.
7.3.2.9.4 Receiver AGC Speed Characteristic Entry
Depress the ‘AGC’ key at 16 successively until the desired Receiver AGC Speed Characteristic appears
on the Operational Display at 17 . The displayed AGC Speed indicates the current Receiver AGC Speed
selection. Three (3) choices are available: Slow (‘AGC-S’), Medium (‘AGC-M’), or Fast (‘AGC-F’).
Depress the Enter (‘ENTR’) key at
6 to store this selection into the currently selected Pre-set Channel.
After the desired AGC Speed Characteristic setting has been entered for the currently selected Pre-set
Channel, proceed to the next Heading. Continue entering or modifying the required Pre-set Channel
settings.
