1. 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.
2. Now be sure your mode selection is still set for the
Main (VFO-A) register, and press the [
CW
] mode key
once more. The “LSB” LED will blink for three sec-
onds, indicating that the “LSB” injection side has now
been selected.
3. When using Dual Receive, just press the [
B
] Mode
key, then press the [
CW
] key to engage CW Reverse
on the Sub (VFO-B) receiver, in exactly the same was
as for the Main receiver.
Press the [
CW
] mode key once more to return to
the normal (USB) injection side and cancel CW
Reverse operation.
In the illustration, Figure A demonstrates the nor-
mal 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 in-
terference.
The beneficial effect of switching sidebands can
clearly be seen in this example.

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.

When CW Reverse is engaged, the Tuning Meter
action will concurrently be reversed as to its indi-
cation.
When the incoming signal pitch tone is properly
aligned, the central LED lights up whether or not
CW Reverse is engaged.
