Ham Fair Tokyo 2015 – Unveiled the Icom IC-7300 「IC-7300でHFの扉を開こう」- IC-7300 adopts the RF Direct Sampling System – Instead of the “conventional” superheterodyne system, Icom utilizes the RF direct sampling system. – (Brochure & Leaflet in ENG and JP below)
This tecnology is seen in SDR (Software Defined Radio) see the block-diagram below. The RF signals path: BPF > A/D Convertr > mostly processed through the FPGA (Field-Programmable Gate Array) have large resources (built-in) to implement complex digital computations. (eliminate physical mixer and filter devices) > DSP Unit > D/A Converter > AF .
IC-7300 HF/50MHz Transceiver HF/6m 100W (EU ver. HF/6m/ 100W and 4m 50W) all modes – Real-time and “serious” .. Spectrum Scope with Waterfall funcion provides top performance in resolution (1 dot) sweep speed and dynamich range (Span width 5kHz – 1000kHz) –
Large Touch Screen user-frienddly interface provides intuitive operation and touch screen for changing frequency!
(1st touch >enlarger frame > 2dn touch .. ok QSY.. see pictures enahanced by radiocronache from hamlife.jp video)
The FT-991 is an traditional superheterodine quad-bands! The new IC-7300 adopt the latest RF direct sampling method (BPF >A/D >FPGA >DSP >D/A – see the Icom block-diagram below) and it is equipped with a high-performance real-time band scope and waterfall on large color TFT touch-screen display!
Q/A at Ham Fair presentation Q1: What FPGA are you using? Xilinx or Altera? A engineer: Cannot tell // Q2: What is the A/D converter and what is its sampling frequency? A engineer: ICOM is still investigating a couple of candidates. The A/D converter sampling frequency is 124MHz. (source: TOHOKU2008 )
According to the engineer at the presentation, ICOM will start shipping IC-7300 by the end of 2015. The target price is under 150,000 JPY
Icom ha presentato oggi (22/8/15) alla Fiera di Tokyo il nuovo IC-7300 con display TFT a touch screen e radio con nuova architettura a campionamento diretto, tipo SDR ed è il primo apparato della Icom (..interessante le Broshure’ in Jp e ora ENG (Icom Uk) link below !)
本日二回目のとなる「IC-7300でHFの扉を開こう」も大盛況！明日もよろしくお願い致します！Ham Fair Tokyo 2015
アマチュア無線機初「RFダイレクト・サンプリング方式」を採用 – (traslate!!) amateur radio’s first to adopt the “RF direct sampling method” BPF >A/D >FPGA >DSP >D/A standalone (as the main amateur radio equipment manufacturer) see the Icom block-diagram below –
Equipped with a large color TFT liquid crystal display that corresponds to the touch panel and QSY operations.
IC-7300 equipped with high-performance real-time scope with a practical skills – a new Icom “compact HF/50MHz transceiver to lead the next generation“
