Whenever the SWR passes thought 2:1, a beep will be heard in addition 
to the SWR dependent tone.  This is especially useful to sight impaired 
users and allows users to know when the SWR is below 2:1. 

 

The audio tone has third important function. In either the VSWR or 
Power Meter mode, it emits a harsh warning tone if you exceed 15W  
applied to the meter, indicating the power needs to be reduced. 
You can adjust the volume of the tome using the volume control on the 
side of 

Stay Tuned

 
If you’d like to turn the audio off, slide the speaker switch, located to the 
left of the ANT BNC connector to the left, towards the left edge of Stay 
Tuned.
