Where is the speech processor adjustment on the Maestro?  6400  HW Version v2.4.9.115

Hi Mike

In the SmartSDR Users Guide, check out Section 20 starting on page 86.  It is very well laid out.

Don't forget the Maestro Users Manual as well:  https://www.flexradio.com/downloads/maestro-user-guide-pdf

You really want to look at 20.3.2.  

The speech processor implements the W9GR Controlled Envelope Single Sideband (CESSB) peak limiting algorithm in SSB, AM and FM modes. The controls are highlighted below in the red square. The processor may be on or off and has three different settings when enabled. In the NOR or normal setting, the processor provides minimal additional gain and simply prevents audio peaks from clipping or producing power greater than the set level. In the DX setting, more gain is provided to the audio to increase the overall sideband envelope which results in a stronger signal that may be more readily heard at a distance. The DX+ setting adds even more gain increasing your talk power or “punch” without incurring significant audio distortion. DX+ is most effective if you increase the low-cut TX filter to between 200-400 Hz to concentrate your talk power in the audio frequency range that has the greatest intelligibility.

More than just pushing a button, it is very good to understand how it works so that you are not transmitting a dirty signal.

Push the Mic/Speed/Pwr button.

Thanks that's exactly what I was looking for.  So simple when one knows which button to push.

As Mike mentions above, read the User Manuals for excellent detailed information.
