Manufactured by Japan Radio Co., Tokyo.
In 1998, the Japan Radio Company launched a new dream receiver that soon became the reference receiver among shortwave listeners: the NRD-545 is equipped with DSP for the first time: the RF signal is digitised and digitally processed - the purchase of high-quality RF filters now no longer depends on your wallet, the filters are programmed electronically.

Since I still don't own an NRD-545, I can only refer to the test reports of well-known authors, fortunately there is a lot to read about the NRD-545…
Triple conversion superhet with digital frequency processing (PLL synthesis) and digital signal processing (DSP), so with digitally programmed IF filters.
The set is solid state.
