The real DX Receiver The 76.899 MHz 4 pole roofling Filter (MCF) and 8 band filter at the RF stage provide excellent suppression of out of band interface

The interference-filtering begins in the “RF” stages, with a double conversion super heterodyne (1st IF 67.899 MHz/ 2nd IF 24 kHz) system. The 8 band-pass filters at the RF input help eliminate out-of-band interference, followed by the RF AMP (2SK520 x 2) that feed into the active DBM (1st local) assure excellent dynamic range. At the 1st IF stage, a powerful 4 pole roofing filter with a 10 kHz bandwidth and excellent shape factor, substantially reduces adjacent signal interference. Then, the YAESU high performance DSP at the 2nd IF stage I 24 kHz permits easy management of AGC, interference rejection, audio tone control, and noise reduction, for clear and quiet reception. The 20 dB ATT (Attenuator) and IPO (Intercept Point Optimization) feature allow the operator to optimize the characteristics of the receiver front end to improve receiver dynamic range.

World class performance in an easy to operate HF?50 MHz transceiver package with yaesu IF DSP.

The legendary YAESU IF DSP system, well regarded among top and world-class DX operators, is now available in an easy to operate package.
The new IF DSP system uses an ANALOG DEVICES, ADSP-BF531 SBST IC, with high speed 16-bit, floating point architecture.
Designed and programmed with the unique objective
of “Enhanced Transmit Signal Quality” and “Advanced Receiving Interference Suppression”.
These features now come in one easy to operate HF/50 MHz Transceiver, ideal for everyone, new licensee or serious DX operator.
