IC-7300 HF/50/70MHz Firmware Update (MAIN Ver.1.14 & FPGA Ver.1.13)

Icom IC-7300 Firmware Update Version 1.14 Update 5/10/2016. The firmware will be updated to the following versions: Main CPU: 1.14 Front CPU: 1.01 – DSP Program: 1.07 – DSP Data: 1.00 – FPGA: 1.13 – This new firmware has been designed to provide several improvements and resolved issues (Icom Inc.)

ver-1-14_mcpu-display-med

Before you install the firmware, download the Icom installation guide and read the official instructions first! – [Note !] Never turn OFF the transceiver power during the update. – Thoroughly read Section 15 (Updating The Firmware) of the “FULL MANUAL” before starting the update. (!!…peccato che nei “Basic Manual” in lingua, la Sez. 15 non sia stata riportata tradotta e quindi si trova solo in inglese! …)

IC-7300 a excitement! – IC-7300 un’emozione! – Basic Manual – RS-BA1 v1.91

IC-7300 HF/50MHz 100W Transceiver – EU version HF/50 MHz /70MHz (50W on 4m) – Receiver system: FPGA Direct Sampling Superheterodine, intermediate frequency: 36kHz (Icom basic manual and sheet) making it possible to simplify the circuit construction.

RF signals are directly converted (ADC) to digital data and processed in the [FPGA] Altera Cyclone IV EP4CE55F2317N perform digital down conversion at IF 36 kHz to IFDSP TI TMS320C6745 – See links below to: IC-7300 Product brochure Eng/EU and ICOM IC-7300  Basic Manual ENG, and VA7OJ’ page

29/1/2016 Icom RS-BA1 Remote Controll Update the Version 1.91
The IC-7300 is now supported (including new IP+ command and real-time spectrum scope screen with waterfal (like IC-7850/51) and other general improvements…. more info to Icom Inc. support web page).

RS-BA1-V-1-91_2016

You must have a previous version of the RS-BA1 software installed BEFORE you can update to version 1.91 (v. previous you purchase) RS-BA1が7300に対応する (ver.1.90 for Japanese users).

New [IP+] Function improves the receiver IMD and the 3rd order intercept point (IP3) performance. When a weak signal is received adjacent to strong interference the ADC is optimized against signal distorsion.

Display-Function-IP+ON

THe IC-7300’s RMDR (reciprocal mixing dynamic range) and Phase Noise characterstics are improved about 15dB (at 1 kHz frquence spacing) comparate to the IC-7200.

RMDR-type

 Audio Scope Function can be used to observe varius AF (audio frequency) characteristics: compressor level, filter width, notch filter width and keying waveform in the CW mode in the FFT scope with the waterfall function and the oscilloscope.

Display-USB-audioscope

The combination of the waterfall function and the real-time spectrum scope assists in maximum receiver performance.

Icom IC-7300 BASIC MANUAL should make interesting reading.

Icom datasheet says they are using technology found in SDR’s (and other devices) – Direct Sampling SDR combined with a Legacy Superheterodyne back end running a 36 kHz IF & DSP – Real-time Spectrum scope plus an multi-functions display touch-screen. 

Icom probably choose to reuse existing DSP’s software developed and engineered for previous latest radios rather than “start from scratch” for their new generation radio starting in IC-7300.
