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” injection).
2. Now be sure your mode selection is still set for VFO-
A, and then press the [ CW
] mode button once more.
The “ ” and “ ” icons will appear in the dis-
play, indicating that the “LSB” injection side has now
been selected.
3. To return to the normal (USB) injection side and can-
cel CW Reverse operation, press the [
CW
] mode but-
ton once more. (the “ ” and “ ” icons will ap-
pear in the display).

ˆ When CW Reverse is engaged, the action of the Tun-
ing Offset Indicator will also be reversed
ˆ
When the incoming signal pitch tone is properly
aligned, the central red marker lights up whether or
not CW Reverse is engaged.
In the illustration, Figure “
A
” demonstrates the nor-
mal CW injection setup, using the USB side. In
Figure “
B ”, CW Reverse has been engaged, to re-
ceive using LSB-side injection and eliminate inter-
ference.
The beneficial effect of switching sidebands can
be clearly seen in this example.
