I’m not sure if this will help anyone, but it will at least serve as documentation in case I have to re-set the TX audio settings on my FT-710. I unfortunately lost my settings for the original hand mic and don’t want to make the same mistake again. Please also note that I am not an audiophile and I really struggled to figure out what sounded good and what did not. In the end, I was happy with the following settings:

The relevant settings here are:

• MIC GAIN: 47
• MIC EQ: ON
• PROC LEVEL: 42

Then, under OPERATION SETTING - TX AUDIO, I’ve configured the following menu items:

Parametric Microphone Equalizer 1 with speech processor enabled:

• P PRMTRC EQ1 FREQ: 400Hz
• P PRMTRC EQ1 LEVEL: 6
• P PRMTRC EQ1 BWTH: 2

Parametric Microphone Equalizer 2 with speech processor enabled:

• P PRMTRC EQ2 FREQ: 1400Hz
• P PRMTRC EQ2 LEVEL: 8
• P PRMTRC EQ2 BWTH: 1

Parametric Microphone Equalizer 3 with speech processor enabled:

• P PRMTRC EQ3 FREQ: 2600Hz
• P PRMTRC EQ3 LEVEL: 9
• P PRMTRC EQ3 BWTH: 1

This is the result, recorded directly on the FT-710 in monitoring mode:
