SR (Spur Reduction):
Activates the Spur Reduction algorithm (see page 84).
BIN (Binaural Audio):
Activates the Binaural algorithm. Binaural audio is a special feature of
PowerSDR. It generates a pleasing effect as the two phased channels (I and Q) are mapped to
the left and right audio channels. The phasing of the demodulated and filtered audio signal
within the passband gives a stereo-like, spatial effect to the received signal. When tuning across
CW signals, they will seem to move in “space” as you tune the radio. Many experienced
operators feel that binaural audio gives them a competitive advantage under contest conditions
where the effect allows them to more easily pick signals out of a pile up. Wearing headphones
increases the effect of the spatial separation.

(12) VFO Controls
Figure 57: VFO Controls
These controls are only available for the main receiver RX1.
SPLT (Split):
Enables Split operation using VFO B (or the lower section of VFO A if RX2 is on,
see page 51) for the transmit frequency. The frequency text in VFO B (or lower part of VFO A)
will turn red to indicate that it is the transmit frequency.
0 Beat:
Centers the signal peak within the RX1 filter passband. An exception is made in CW
mode if the CW Pitch is within the passband. In this case, the signal is tuned to the CW Pitch.
Note:
0 Beat
is only available if
AVG
is enabled for the Display.
IF
→
V:
Translates any offset created by Filter
Shift
and shifts it back to baseband. Useful when
chasing a signal with the Filter
Shift
control (see also page 58).
A

B:
Transfers the contents of VFO
A
to VFO
B
(frequency, mode, and filter). If RX2 is on, this
tunes RX2 to the same frequency RX1 is on.
A
<
B:
Transfers the contents of VFO
B
to VFO
A
(frequency, mode, and filter). If RX2 is on, this
tunes RX1 to the same frequency RX2 is on.
