FT-950
Operating Manual
will appear in the display if you select CW Reverse.
2.Rotate the Main Tuning Dial knob to select the desired operating frequency.
3.Press the [BK-IN] button to engage automatic activation of the transmitter when you close the CW key. The “BK-IN” icon will appear in the display.
Advice:
When you close your CW key, the transmitter will automatically be activated, and the CW carrier will be transmitted. When you release the key, transmission will cease after a brief delay; the delay time is user-programmable, per the discussion on page ??.
As shipped from the factory, the FT-950 TX/RX system for CW is configured for “Semi-break-in” operation. However, using Menu item “043 A1A BK-IN,” you may change this setup for full break-in (QSK) operation, whereby the switching is quick enough to hear incoming signals in the spaces between the dots and dashes of your transmission. This may prove very useful during contest and traffic-handling operations.
4.Operation using your CW key may now proceed.
Advice:
You may adjust the CW sidetone level by the [MONI] knob. Rotate the [MONI] knob for a comfortable listening level on the CW sidetone. To disable the CW monitor, press the [MONI] button (the “MONI” icon is disappeared).
If you set the [BK-IN] button to Off, you may practice your sending without having the signal go out over the air (sidetone only).
If you reduce power via the Menu item “111 TGEN TX PWR”, the ALC meter reading will increase; this is normal and does not indicate any problem whatsoever (because increased ALC voltage is being used to lower the power).
Terminology: Semi-break-in
This is a pseudo-“VOX” mode used on CW, whereby the closure of the CW key will engage the transmitter, and release of the key will allow the receiver to recover after a short delay. No signals will be heard between the spaces between dots and dashes (unless the sending speed is extremely slow).
Full break-in
Full break-in (also known as “Full QSK”) involves very fast switching between transmit and receive, such that incoming signals may be heard between the dots
