Tuning Knob
The
Tuning Knob
makes it possible to adjust the frequency in fixed 50 Hz,
500 Hz, 5 kHz or 50 kHz steps.
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).
You don’t need to move up or down with the cursor to change the rotation of
the knob. Simply press either the right or left mouse button.
As the knob rotates, the frequency will change in 500 Hz steps. Holding the
mouse button down will accelerate the tuning.
The step size can be changed to 50 Hz, 5 kHz or 50 kHz, using the
Alt
,
Shift
or
Ctrl
keys, respectively, while clicking the tuning knob with mouse button.
Note that the Fine Tune Knob can also be conveniently rotated using a wheel
of a wheel-equipped mouse, or any other standard Windows-supported
pointing device.
Keyboard Tuning
The receiver frequency can also be adjusted using the keyboard cursor control
keys: Using the up/down arrow keys, the frequency changes in 500 Hz steps
for AM, AMS and FMN modes, 10 Hz steps for LSB, USB, DSB, ISB and CW
modes and 50 kHz steps in the optional FMW mode. Using the
Shift
key
multiplies the step by 10, the
Ctrl
key multiplies it by 100.
