Passband tuning
The passband tuning control duplicates the function of dragging the
demodulator passband using the right mouse button. These two methods are

visible and can be precisely adjusted.

Passband tuning makes it possible to finely adjust the demodulator filter
position in the AMS, LSB, USB and CW modes without a whistle effect due to
a misaligned BFO, making it possible to avoid interference and finely tune the
receiver for optimum reception.

Pressing the Reset button sets the passband tuning offset to zero.
