Fine Tuning
The Fine Tune knob makes it possible to finely adjust the frequency in
0.5 kHz steps.
WiNRADiO G303 Receiver Tuning Knob
To use the tuning knob, position the mouse cursor over the knob (the cursor
will turn into a curved double ended arrow) and click on either the left or right
mouse button. If the cursor is on the top half of the knob, the left button will
decrease the frequency, and the right button will increase the frequency. If
the cursor is in the lower half, the opposite will occur (and the cursor will
invert its shape).
Using the keyboard only, the frequency can be similarly adjusted using the
up/down cursor keys.
To speed up tuning, the step size can be increased ten or one hundred
times by holding the Shift or Ctrl keys respectively, while clicking the tuning
knob with the mouse button or using the up/down keyboard keys. This is a
very convenient feature if you wish to tune quickly across a frequency range:
hold the mouse button and accelerate the movement by pressing the Shift
or Ctrl keys. On the other hand, pressing the Alt key will reduce the tuning
step ten times (to 50 Hz).
Note that the Tuning Knob can also be conveniently rotated using a wheel-
equipped mouse, or any other standard Windows-supported pointing device.
Taking advantage of this facility, it is possible to emulate the “feel” of a
conventionally tuned receiver.
