Adjusting The Ssb Transmitted Bandwidth - Yaesu FT DX 3000 Operating Manual

djUsTing The
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 ] button to engage the Menu.
2. Rotate the [ CLAR/VFO-B ] knob (or press the p/q
button) to select Menu item "104 SSB TX BPF".
3. Press the [ SELECT ] button, then rotate the [ CLAR/
VFO-B ] knob (or press the p/q button) to select
the desired bandwidth. The available selections are:
100-3000 Hz, 100-2900 Hz, 200-2800 Hz, 300-2700
Hz and 400-2600 Hz. The default is 300-2700 Hz. A
wider bandwidth will provide greater fidelity. A nar-
row bandwidth will compress the available transmit-
ter 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 op-
eration.

The Transmit Monitor function is a very helpful way to
confirm 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.

The higher fidelity associated with wide bandwidth will
be particularly enjoyable on the low bands during local
rag-chew QSOs.
