CW CONVENIENCE FEATURES

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.

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) regis- ter, 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. 3. When using Dual Receive, press the [B] button, then (within five seconds of pressing the [B] button) press the [CW] button to engage CW Reverse on the Sub (VFO-B) receiver, in ex-

actly the same way as for the Main (VFO-A) receiver.

4.Press the [CW] mode button once more to return to the normal (USB) injection side and cancel CW Re- verse operation (the “USB” LED will blink for three seconds).

NOTES:

￿When CW Reverse is engaged, the Tuning Offset In- dicator action will concurrently be reversed as to its indication.

￿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 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 in- terference.

The beneficial effect of switching sidebands can clearly be seen in this example.
