This review was compiled independently. The Medium Wave Circle and Radio Netherlands has no financial connection with Japan Radio, the manufacturer of this receiver.

In August 1997, JRC previewed the replacement for the NRD-535 series. Product shipped in quantity in mid-1998. It is similar in appearance to the JST-245 amateur band transceiver. The NRD-545 DSP (digital signal processing) receiver additionally features continuous IF filtering from 40 Hz to 10 kHz with 10 Hz step (no mechanical/crystal filters are necessary); 1000 memory channels; a timer that is more than just a one-event; and more.

The receiving system employs a triple conversion circuit with IFs at 70.455 MHz, 455 kHz and 20.22 kHz. The NRD-545 uses a 40-bit extended floating point Digital Signal Processor with an 18-bit over-sampling system A/D converter and a 16-bit D/A converter. The DSP functions on 13 types of circuits after the IF, previously configured using analogue circuits. DSP is used for all-mode detection including AM synchronous detection (ECSS).

We have not tested this receiver.
