Press the CW mode switch toengage CW operation. The operating mode is selected us-ing the Mode switches to the left ofthe tuning dial, and the VFO (A orB) to which the selection is appliedis selected by pressing the A orB switch above the Mode keys.Please be sure you are engaging CWon the right VFO. The LED associated with your VFOand (CW) Mode selection will lightup. If you press the CW key once more, after initially selectingCW, you wll engage the “CW Reverse” mode (see page 104),whereby the “opposite” sideband injection is used, comparedto the “normal” sideband. The CW LED will blink for threeseconds if you select CW Reverse.2. Rotate the Main Tuning Dial to select the desired op-erating frequency.3. Press the BK-IN/SPOT key(# ) momentarily to engage au-tomatic activation of the transmit-ter when you close the CW key.The LED imbedded in the BK-IN/SPOT switch will light up. When you close your CW key, the transmitter will automati-cally be activated, and the CW carrier will be transmitted.When you release the key, transmission will cease after a briefdelay; the delay time is user-programmable, per the discus-sion on page 105. As shipped from the factory, the FT DX 9000D TX/RX systemfor CW is configured for “Semi-break-in” operation. How-ever, using Menu item MODE-CW 047 CW BK-IN, you maychange this setup for full break-in (QSK) operation, wherebythe switching is quick enough to hear incoming signals in thespaces between the dots and dashes of your transmission. Thismay prove very useful during contest and traffic-handlingoperations.4. Operation using your CW key may now proceed.Terminology Semi-break-inThis is a pseudo- “VOX” mode used on CW, whereby the closure of the CW key will engage the transmitter, andrelease of the key will allow the receiver to reciver after a short delay. No signals will be heard between the spacesbetween dots and dashes (unless the sending speed is extremely slow). Full break-inFull break-in (Also known as “Full QSK”) involves very fast switching between transmit and receive, such that incom-ing signals may be heard between the dots and dashes as you send them. this allows you to hear a station that suddenlystarts transmitting on your frequency, while you are in the midst of a transmission.CW switchMain Tuning DialBK-IN switchAdvice You can monitor your sending by pressing theMONI key, and adjust the MONI control for acomfortable listening level on the CW sidetone. If you set the VOX and BK-IN switches to Off,you may practice your sending without having the sig-nal go out over the air (sidetone only).
