Tuning Methods
Spectrum Drag and Click
The easiest way to tune signals on the display when set to Panadapter or Waterfall is simply to click on
the signal, and drag it into the filter area. You can also drag the displayed filter edges to adjust the filter
width as well. This will work for RX1 and RX2, depending on which Panadapter/Waterfall the mouse
cursor is in.
Mouse Wheel
A mouse wheel is the next easiest way to tune the radio. While the PowerSDR window is active, tune
VFO A
using the mouse wheel, with the mouse cursor anywhere on the screen. The frequency will
change in steps equal to the selected
Tune Step (2)
for each click of the mouse wheel. Adjust the
Tune
Step
using the controls, clicking the mouse wheel or pressing Ctrl + Left or Right Arrow key.
If RX2 is installed and on, then the mouse wheel will tune
VFO B
only if the mouse pointer is anywhere
in the RX2 Panadapter or Waterfall display.
Note:
When the
Tune Step
equals 1kHz, each click of the mouse wheel will
first snap tune up or down to the nearest 1kHz and then change in
1kHz steps. E.g. if
VFO A
is tuned to say 14.000258MHz then with
the tuning rate set to 1kHz, using the mouse wheel to tune up will
first increase
VFO A
to 14.001000MHz and then to 14.002000MHz,
and so on.
Hint:
Holding down the Shift key while turning the mouse wheel will change
VFO A
(or for RX2
VFO B
) at the next lower
Tune Rate
.
Mouse Wheel Hover
Hover with the mouse over a digit in either
VFO A
or
VFO B
(or the lower part of
VFO A
if applicable)
and increase or decrease its value using the mouse wheel. The digit to be tuned will be underlined.
Spectrum Click Tuning
With the RX1 display set to Spectrum, Panadapter, Waterfall or Histogram, hover with the mouse over
the RX1 display and right click to cycle through yellow cross-hairs to tune
VFO A
, red cross-hairs to
tune
VFO B -
or the
lower part of VFO A
if RX2 is on - (only if
VFO B
is active, e.g. when
SPLT
(12)
and/or
MultiRX (10)
are activated), or no cross-hairs (click tuning off). With the cross-hairs
visible, hover over the desired signal in the RX1 display and click the left mouse button. The
corresponding VFO will immediately tune to the frequency of the selected signal.
If RX2 is installed and on, hover with the mouse over the RX2 display and right click to activate the
yellow cross-hairs; right click again to turn click tuning off. With the cross-hairs visible, hover over the
