Using Cw Reverse - Yaesu FT DX 3000 Operating Manual

cW c
Onvenience
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 move the interfering station's frequency in a direction that
may lend itself more readily to rejection.
1. To start, let's use a typical example where you have
set the CW mode (using the default "USB" injec-
tion).
2. Now be sure your mode selection is still set for VFO-
A, and then press and hold in the [ MODE ] button for
one second. The "LSB" and "CW" will appear in the
display, indicating that the "LSB" injection side has
now been selected.
3. To return to the normal (USB) injection side and
cancel CW Reverse operation, press and hold in the
[ MODE ] button for one second. (the "USB" and
"CW" will appear in the display).

In the illustration, Figure "A" demonstrates the
normal CW injection setup, using the USB side.
In Figure "B", CW Reverse has been engaged to
receive using LSB-side injection and eliminate
interference.
The beneficial effect of switching sidebands can
be clearly seen in this example.
