<h4>4.1: Activate vox system</h4>
Toggle this switch to activate or de-activate vox control. When activated the audio input level is monitored and appears in (4.5) and if the level exceeds the level set by (4.3) and displayed in (4.4) then the vox button turns green until vox goes off after the hold period (4.6). The vox system controls the PTT only if the vox PTT enable checkbox is checked (4.2). Thus you can set the appropriate level (4.3) before engaging PTT control.
Right click on this button to open the audio input device selection dialog.
<h4>4.2: Enable PTT control</h4>
Check this box to enable PTT control by the vox system.
<h4>4.3: Vox threshold level</h4>
Use this button to adjust the vox threshold level in power dB (0 dB = full range)
<h4>4.4: Vox threshold display</h4>
This is the value set by (4.3) in dB.
<h4>4.5: Audio input level</h4>
This is the audio input level in dB displayed when the vox system is active (4.1)
<h4>4.6: Vox hold period</h4>
The vox is held active for this amount of time in milliseconds after the audio input power goes below the threshold level (4.3)
