IC-7300 the User Evaluation & Test Report  by Adam, VA7OJ’ is now on-line on his web-site – See the link below for download a large pdf  (total pages 40) – (tante grazie Adam per  l’interessante ed ampio tuo report-test).  – The Report (Iss. 1) describes the evalutation of IC-7300 S/N 02001981 from a user perspective. The Appendix 1 presents results of RF lab test suite performed on the radio.

IC-7300 OVF-colsein-02

ADC Clip Levels – (light the on-screen OVF red icon) OVF indication occurs only when a strong out-of-channel signal is present. In-channel signals cause AGC action which attenuates the signal at the Rx ADC imput  (LTC2208-14) via an diode PIN BAP70Q (D1251).

Recirpocal Mixing Noise occurs in a direct-sampling SDR receiver when the phase-noise sidebands of the Rx ADC clock mix with strong signals close in frequency to the wanted signal, producing unwanted noise products in the detection channel and degrading the receiver sensitivity.
RMDR (reciprocal mixing dinamic range) VA7OJ, Adam Test condition: CW mode, 500 Hz filter, max RF Gain Preamp off, ATT off, NR off, AGC-M. NB off – (…. I point to only two numbers below):
Ofset frquency:    2 kHz RMDR: 109 dB & Phase noise: -136 dBc/Hz

IC_7300 the firts impressions of the new Icom HF/50MHz direct sampling transceiver – Report and video from Orlando Hamcation on February 13, 2016 by AB4BJ  – Icom USA had a demonstration model on display that was shipped from Japan just for this show.  As far as know, it’s the one and only IC-7300 on display in the USA at this time. – Read more, see the video and link to ab4bj blog below…

IC-7300-Orlando-16

One of the great features of this radio is the big real-time spectrum scope with waterfall.  It also has a great  real-time audio scope. Tanks to AB4BJ of test out the IC-7300 on February 13, 2016 during Orlando Hamcation, thanks to Ray Novak, N9JA and Will Jourdain, KI4VXF of Icom America.

Following are the short videos made in YouTube by AB4BJ Blog Home-page an Extra Class Amateur Radio operator in Calhoun, Georgia,  we took as we listened to the radio and worked through some of its many features and functions. (! tanks AB4BJ)
[Note]  The radio is expected to be in production and available for sale by the end of March, 2016.

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.
