(300-2700 Hz), 4-26 (400-2600 Hz) , 3000WB and the default is 3-27 (300-2700 Hz). A wider bandwidth will provide greater fidelity, while a narrow bandwidth will compress the available transmitter power into less spectrum, resulting in more “talk power” for DX pile-ups.

4.Press and hold in the [MENU] button for two seconds to save the new setting and exit to normal operation.

Advice:

The Transmit Monitor is very helpful way of verifying the effects on fidelity of changing the bandwidth. Pressing the [MONI] button then adjusting the [MONI] knob for a comfortable listening level while you are transmitting, you will be able to hear the difference in sound quality as you make changes.

When the optional DMU-2000 Data Management Unit is connected, you may verify the effect of your adjustments of the transmitted bandwidth by observing the Audio Scope on the “Oscilloscope” page.

Quick Points:

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

The “3000WB” setting is a special hi-fidelity setting, whereby the transmitted bandwidth is in excess of 3 kHz. This selection, in conjunction with judicious adjustment of the Parametric Microphone Equalizer (see next chapter) can provide truly outstanding fidelity and very natural-sounding audio.

When using the wider bandwidth selections (especially “3000WB”), the apparent power output from the transmitter may seem lower. This is because the available power from the transmitter is being distributed over a wider bandwidth, and the power detection circuitry does not compensate for the effect of the bandwidth selection (it is calibrated in the default 2.4 kHz bandwidth).

Parametric Microphone Equalizer (SSB/AM/FM mode)

The FT-950 includes a unique Three-Band Parametric Microphone Equalizer that provides precise, independent control over the low, mid and treble ranges in your voice waveform. You may utilize one group of settings when the speech processor is off, and an alternate group of settings when the speech processor is on. The speech processor feature is described in the next chapter.
