RT-9000 B
Figure 7.3.3.22 CW-Mode Filter Selection Feature Menu
The RT-9000 B is equipped with a Narrow-Band Audio CW filter. If this filtering function is desired, depress
the key beneath ‘CW-NAR’ on Feature Menu to switch in this filter. An asterisk (*) will appear next to the
Feature Menu ‘CW-NAR’ choice indicating it has been enabled.
CW Key Break-Time is a system setting that controls the amount of time the RT-9000 B Transceiver remains
in Transmit mode after an operator stops sending Morse code. Three (3) CW Key Break-Time choices are
available to the operator and are described in the following chart.

The CW Key Break-Time setting is normally set to “CW-Medium” when the equipment is shipped from the
factory. This setting will normally meet most operator sending speeds. If the operator wishes to change this
setting, perform the following steps.
Select CW-Mode as previously described for CW Filter. The Feature Menu described in Figure 7.3.3.22 will
appear. Depress the key beneath desired Feature Menu choices as described in the above table. An asterisk
(*) will appear next to the Feature Menu choice indicating it has been enabled.
Depress the ‘MORE’ key to leave the CW-Mode Options menu and return to the main menu.
To change CW Filter and/or Key Break-Time settings if currently in CW mode, depress the ‘MODE’ key
successively until ‘CW’ Mode reappears in the Operational Display. This action will cause the Feature Menu
shown in Figure 7.3.3.22 to reappear and allow the operator a new choice as previously described.
