The mixer of the 1st IF stadium for HF/ 50 MHz is a quad mixer with four Mos-Fet 3sk294 dual-gate devices that offer very low noise, excellent intermodulation characteristics and a high dynamic range. A dedicated mixer for VHF/UHF bands, separated from the HF bands, allows design optimization for the frequencies concerned, with consequent higher level performance. The IF Width and If Shift functions, which are the basis for the elimination of interference, are naturally integrated to optimize the effect. The effectiveness of the rejection of interference is further increased by the sophisticated functions inherited from the FT-DX series, such as the digital reduction of 16-stage noise and the DNF (Auto Notch) filter which quickly traces multiple beats quickly. The Contour function that eas.
