IC-7851 – Icom Inc. Japan announces the IC-7851 a new flagship HF/50MHz 200W Transceiver, the series-production version of the IC-7850 (limited edition) which offers a number of improvements over the IC-7800. (Download the large broshure JPN – link below)
Icom is top priority to the performance than the cost, (JP 価格 希望小売価格 1,100,000円＋税 !) excellent 1.2kHz narrow band filter of IMD characteristics in the 64MHz 1st IF stage “Optimum Roofing Filter” was carefully adopted.
IC-7851 New Front-end: BPF switching, automatic pre-selector of CPU control, D-MOS FET array use of ultra-high dynamic range receiver mixer and 1st IF Roofing Filter.
Three DSP & 24-bit AD/DA conveter – ADSP-21489- 32-bit floating-point maximum processing speed: 2400MFLOPS, internal clock operation at about 393 MHz
IC-7851 RMDR: 110dB at 1kHz detuning (spacing) (typical) (reception frequency: 14.2MHz, MODE: CW, IF BW: 500Hz, Roofing 1.2kHz) that you can not reach the area you could not talk in a conventional machine.
* 1.2 kHz 1st-IF roofing filter optimized for shape factor and passive IMD * New DDS/PLL LO, with much lower phase noise than the existing IC-7800 LO * FFT spectrum scope and waterfall via dedicated scope DSP * Separate real-time scope/waterfall fields for Main and Sub receivers * Enhanced mouse functionality * USB, Ethernet and S/P-DIF interfaces * SD card slot; firmware updates via SD card or USB thumb-drive – Link to: 【IC-7851】唯一、無比のデュアルスコープ、圧倒的なRMDR特性で頂点を極めたフラグシップ機 (JPN)
