Adjusting Your Rig’s DSP Settings

DSP Setting Example: Yaesu FT-950/2000 and FTdx9000 Series
These rigs use a three-band parametric equalizer system. In each of the audio “bands” (low, mid, and high frequency areas), you can set the center frequency, amplitude, and bandwidth of equalization. Generally, the modulators of these rigs want you to roll off bass and enhance treble.
The menu numbers vary from radio to radio, and are not even consistent within the vintage of the FTdx9000, so follow these guidelines according to function.
Set EQ1 Frequency to 200 Hz, EQ1 Level to -10, and EQ1 Bandwidth to 1. Set EQ2 Frequency to 900 Hz, EQ2 Level to -10, and EQ3 Bandwidth to 2. Set EQ3 Frequency to 2100 Hz, EQ2 Level to +10, and EQ3 Bandwidth to 2. Use the same settings for the “Processor On” menu items.
Set the SSB TX Bandwidth to 200-2800 Hz for high-fidelity rag-chews, or to 400-2600 Hz for DX work.
The speech processors of these rigs are very touchy. You may find it easier to get additional talk power, without distortion, by leaving the processor off and utilizing the 400-2600 Hz transmit bandwidth, perhaps with a little additional mic gain thrown in. Listen on your monitor receiver to be sure the audio quality is what you are trying to achieve.
Note that the mics and boomsets using the HC-5 elements (GM-5, Pro Set 5, etc.) are particularly well suited for these rigs, and particularly so in the case of the FT-950.
When using the PR 781 microphone with the FT-950, we recommend you set Menu #65 and #66 (Carrier Shift) to +200 Hz to remove some of the bass response.
