Just got a new feature for us in the latest bta k3 firfmware.
Now, at the end of an antenna tuning cycle, it emits a beep. The pitch of
this beep relates the swr found.
beep same as switch tone, less than two to one.
beep somewhat higher, less than three to one,
higher yet, greater than three, and very low pitch, unable to measure.
sorry for the typing, hard to do in a sling. just had a rotator cuff fixed.
83.
