 NB (Impulse Noise Blanker): Activates the Noise Blanker algorithm.
 NB2 (Mean Noise Blanker): Activates the Mean Rank Noise Blanker algorithm.
 SR (Spur Reduction): Activates the Spur Reduction algorithm.
 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 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.

 SPLT (Split): Enables Split operation using VFO B for the transmit frequency. The frequency text
in VFO B will turn red to indicate that Split operation is active.
 0 Beat: Takes the peak signal and sets it to the center of the filter passband. An exception is made
while 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: Takes any offset based on Filter Shift and the Filter Width and shifts it back to baseband.
Useful when chasing a signal with the Filter Shift control.
 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).
