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.
