14.000.70 MHz; the latter frequency is what the FT-2000 displays, by default.
However, you can change the display to be identical to that of what you would see
on SSB by using Menu item “060 A1A FRQDISP” and setting it to “dIr” instead of
its default “OFSt” setting.

Using CW Reverse
If you experience a difficult interference situation, where an interfering station cannot
readily be eliminated, you may wish to try receiving using the opposite sideband. This
may throw the interfering station’s frequency in a direction that may lend itself more
readily to rejection.
To start, let’s use a typical example where you have set the CW mode (using the default
“USB” injection) onto the Main (VFO-A) receiver.
Now be sure your mode selection is still set for the Main (VFO-A) register, and
press the [CW] mode button once more. The “LSB” LED will blink for three seconds,
indicating that the “LSB” injection side has now been selected.

When using Dual Receive, press the [B] button, then (within five seconds of
pressing the [BN] button) press the [CW] button to engage CW Reverse on the Sub
(VFO-B) receiver, in exactly the same was as for the Main (VFO-A) receiver.
(VFO-B) receiver, in exactly the same was as for the Main (VFO-A) receiver.
Press the [CW] mode button once more to return to the normal (USB) injection side
and cancel CW Reverse operation (the “USB” LED will blink for three seconds).
In the illustration, Figure A demonstrates the normal CW injection setup, using the
USB side. In Figure B, CW Reverse has been engaged, so as to receive using LSB-side
injection to eliminate interference.
The beneficial effect of switching sidebands can clearly be seen in this example.
Note
When CW Reverse is engaged, the Tuning Offset Indicator action will concurrently
be reversed as to its indication.
When the incoming signal pitch tone is properly aligned, the central red LED lights
up whether or not CW Reverse is engaged.
CW Delay Time Setting
During semi-break-in (not QSK) operation, the hang time of the transmitter, after you
have finished sending, may be adjusted to a comfortable value consistent with your
