NRD-545 DSP  Used Model SHR12014

Classic used HF communications receiver, this JRC  NRD545DSP also has the desirable CHE-199 board fitted which extends the frequency range to 1999.999MHz.

The top case has some minor scratch marks  but otherwise in excellent used condition and will have our 6 month warranty. Supplied with mains lead and operator manual.

  • 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.
  • DSP Notch Filter (NOTCH)
  • Beat sounds are attenuated (>40dB) using the steep attenuation characteristic of the notch filter. Despite its steep characteristics, beat sounds are digitally processed and attenuated when the NOTCH is reset. It is adjustable within ±2.5 kHz (in 10 Hz steps). The Notch follows in the range of ±10 kHz even when the tuning dial is rotated.
  • DSP Notch Automatic Gain Control (AGC)
  • Digital AGC is applied to all modes (except WFM). The AGC is continuously adjustable between 0.04 and 5.1 seconds in 20 msec. steps in all modes except FM, AM and AMS.
  • DSP Beat Frequency Oscillator (BFO)
  • The BFO generates signals in the LSB, USB, CW and RTTY modes.
  • DSP RF Gain (RF)
  • The information transferred to the RF GAIN control via the A/D converter is entered into the DSP to adjust gain inside the DSP and the gain of the primary IF amplifier.
  • DSP Squelch (SQ)
  • The Squelch function is available in all modes.
  • DSP Tone Control (TONE)
  • The audio quality may be adjusted in all modes (except RTTY & WFM) in the range of 1 to 10 kHz.
  • DSP S-Meter
  • The signal level is determined in reference to the input signal to the DSP and the level is converted into an antenna input level, which activates the S-meter.

  • Power ............... 100/120/220/240 VAC
