Figure 54: Cursor and Peak Position Information
In the frequency domain displays (Spectrum, Panadapter, Histogram, Waterfall), right clicking
the mouse cycles through yellow crosshairs, red crosshairs (only if SPLT or MultiRX is
enabled), or no crosshairs. The crosshairs span the width and height of the display (yellow
cross hairs are shown in Figure 54 above).
Together with the AVG control they allow easy measurement of signals on the display. For
example, in Figure 54 the cursor position is offset -10230.3 Hz from the VFO frequency and is
at 14.176770 MHz. Its “level” is at -80.6 dBm.
Another feature of the crosshairs is ClickTuning. Clicking the left mouse button with the yellow
crosshairs visible tunes VFO A (and for RX2 VFO B) to the frequency indicated by the cursor
position data (or if Snap ClickTune is on (see page 85), to the nearest multiple of the Tune
Step). The red crosshairs tune VFO B if RX2 is either not installed or off, or the lower section of
VFO A (see page 51). This is an excellent way to tune CW signals as it will zero beat the tone
to the set CW pitch.
(10) MultiRX Controls
The MultiRX controls, shown below, allow you to enable a second receive channel for RX1 only within
the receiver's passband, which is determined by the audio sample rate setting. Both the primary and
the secondary receive channel can be positioned independently in the audio spectrum to facilitate
separating the two signals in your head.
Figure 55: MultiRX Controls
Click MultiRX to enable the second receive channel. The second receive channel will be tuned to the
frequency shown in either VFO B if RX2 is not installed or off, or in the lower section of VFO A if RX2 is
on (see page 51). In the Panadapter and Waterfall Displays, its passband is shown in blue, but only if it
