ADJUSTING THE SSB TRANSMITTED BANDWIDTH (SSB MODE)

For transmission on SSB, a default bandwidth of 2.4 kHz is provided. This bandwidth provides reasonable fidelity along with good talk power, and is typical of the bandwidth used for decades for SSB transmission. The bandwidth may be varied by the operator, to provide different levels of fidelity or talk power, according to your preferences.


Here are the steps to adjust the SSB transmit bandwidth:

    1. Press the MENU knob to engage the Menu.

    2. Rotate the [VFO-B/CLAR] knob (or press the ▲ ▼ button) to select Menu item "104 SSB TX BPF".

    3. Press the [SELECT] button, then rotate the [VFO-B/CLAR] knob (or press the ▲ ▼ button) to select the desired bandwidth. The available selections are:

100 - 3000 Hz, 100 - 2900 Hz, 200 - 2800 Hz, 300 - 2700 Hz, 400 - 2600 Hz, and 3000 WD. The default is 300 to 2700 Hz. A wider bandwidth will provide greater fidelity. A narrow bandwidth will compress the available transmitter power into less spectrum, resulting in more "talk power" for DX pile-ups.

    4. Press the [SELECT] button, then press the [MENU] button to save the new setting and exit to normal operation.

ADVICE:
The Transmit Monitor function is a very helpful way to confrim the effect that changing the bandwidth will have on fidelity. By pressing the [MONI] button, you will be able to hear the difference in sound quality as you make changes.





QUICK POINTS:
The higher fidelity associated with wide bandwidth will be particularly enjoyable on the low bands during rag-cheq QSOs.
