20.6 RECOMMENDED AUDIO ADJUSTMENT STEPS FOR PHONE MODES

The use of a second receiver to monitor your transmitted audio in real-time is the preferred

method for making the adjustments listed below. Otherwise, use the Quick Record and Playback

procedure described above for monitoring your transmitted audio and making the following

adjustments.

 Select the desired microphone input from the list in the TX Menu.

 Select the desired transmit filter width on the TX Menu.

 Turn the speech processor off by pressing the PROC button in the TX Menu so that it is not

highlighted.

 Adjust the TX Equalizer to compensate for the microphone and operating conditions. The

default setting is a good starting point for most microphones. The TX EQ is located after

the processor in the signal chain, so it should typically be adjusted before engaging the

processor. Minor adjustments can be made after engaging the processor, but care is

needed to avoid excessive peaks.

 Speak into the microphone at the loudest voice level you would normally use.

 Adjust the microphone gain control so that the peak indicator hovers near 0 VU on the

Level meter. Most microphones will require the +20 dB gain preamp to be enabled on the

Phone/CW tab of the Main Menu.

 Turn on the speech processor with the PROC button. The adjacent slider sets the

Compression setting. In most cases use the NORM (normal) setting. Selecting DX and DX+

adds additional compression without distorting the audio.

 Readjust the transmit equalizer to optimize the audio for your voice characteristics, the

desired operating style, and microphone response once PROC is enabled.

 Enable the DEXP, setting it for your operating position’s ambient background noise. Ideally,

any device that generates background noise should be on so that the DEXP is optimally

configured.

 If VOX operation is desired, enable the VOX button and adjust the VOX gain/delay for

proper operation.

The settings described above are included in MIC profiles. After the controls are adjusted, their

settings can be saved for future use by storing a MIC profile. See section 16.1, MIC Profiles.
