DSP All-Mode Detection
DSP signal detection in all modes including LSB, USB, CW, RTTY, FM, AM and ECSS.
DSP IF Filter
Superior selectivity is achieved by a simultaneous Chebyshev type digital IF filter with an infinite impulse response configuration. The pass bandwidth is continuously adjustable from 10 Hz to 9.9 kHz in 10 Hz steps (BWC).
DSP Pass-Band Shift (PBS)
Radio interference is pushed out of the band by shift the center frequency of the digital IF filter upward or downward in the variable range of ±2.3 kHz (in 50 Hz steps).
DSP Noise Reduction (NR)
Signal processing is adjustable in 256 steps, allowing the most audible conditions to be set. The NR function is effective for such noise that the noise blanker cannot handle.
DSP Beat Canceller (BC)
Periodic signals such as beat sounds (hets) can be exalted and cancelled.
DSP Noise Blanker (NB)
NB-1 (narrow blanking width) and NB-2 (wide blanking width) can be switched over and the NB detection level is adjustable.
