NB2 (Mean Rank Noise Blanker): Activates the Mean Rank Noise Blanker algorithm (see
page 83).
SR (Spur Reduction): Activates the Spur Reduction algorithm (see page 66).
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.
Note: BIN is not available when operating FMN, AM or SAM.
(12) VFO Controls
Figure 54: VFO Controls
SPLT (Split): Enables Split operation using VFO B for the transmit frequency. The frequency
text and TX indicator in VFO B will turn red to indicate that it is the transmit frequency.
0 Beat: Centers the signal peak within the RX 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 43).
A >B: Transfers the contents of VFO A to VFO B (frequency, mode, and filter).
A< B: Transfers the contents of VFO B to VFO A (frequency, mode, and filter).
A< >B: Swaps the contents of VFO A and B (frequency, mode, and filter).
