(10) Sub-RX Controls
The Sub-RX controls, shown below, allow you to enable a second, sub-receiver. In essence this is a second
audio passband within the total passband determined by the sound card’s sampling rate. Both the main and
the sub-receiver can be positioned independently in the audio spectrum to facilitate separating the two
signals in your head.
Figure 47: Sub-RX Controls
Click Sub RX to enable the second receiver. The Sub-RX will be tuned to the frequency shown in VFO B.
In the Panadapter Display, the sub-RX passband is shown in blue, but only if it is within the range of the
Panadapter. Use the upper and lower horizontal sliders to position the Main and Sub-RX respectively
anywhere in the left-right audio spectrum. Use the left and right vertical sliders to adjust the volume of the
Main and Sub-RX respectively. Check mark Swap if to swap the audio from the left and right speakers.
