Icom IC-7300 HF Digital Transceiver

System Overview

The Icom IC-7300 is a revolutionary compact radio that will excite HF operators from beginners to experts.

This new model has a high-performance real-time spectrum scope and employs a new RF direct sampling system.

The Icom IC-7300’s real-time spectrum scope provides top-level performance in resolution, sweep speed, and dynamic range. While listening to received audio, the operator can check the real-time spectrum scope and quickly move to the intended signal.

The combination of the real-time spectrum scope and waterfall function improves the quality and efficiency of HF operation.

The new RF direct sampling system employed by the Icom IC-7300 realizes class-leading RMDR (Reciprocal Mixing Dynamic Range) and Phase Noise characteristics. In addition, a large touch screen color TFT LCD, convenient multi-function dial knob, automatic antenna tuner, voice recorder function, and more.

Class Leading Real-Time Spectrum Scope

You no longer have to choose whether to listen to the audio or have the spectrum scope sweep for signals as the IC-7300’s real-time spectrum scope offers the simultaneous operations found in higher-tier models.

This means you can use either the spectrum scope or the waterfall to quickly move to an intended signal while listening to the receiver audio.

The IC-7300’s touchscreen introduces a “Magnify” function. So, when you first touch the scope screen around the intended signal, the touched part is magnified.

A second touch of the scope screen changes the operating frequency and allows you to accurately tune.

High-Resolution Waterfall Function

The combination of the waterfall function and the real-time spectrum scope assists in the maximum receive performance of the IC-7300 and increases QSO opportunities without missing weak signals.

The waterfall function shows a change of signal strength over some time and allows you to find weak signals that may not be apparent on the spectrum scope.

Audio Scope Function

The audio scope function can be used to observe various AF characteristics such as microphone compressor level, filter width, notch filter width, and keying waveform in the CW mode.

Either the transmit or receive audio can be displayed on the FFT scope with the waterfall function and the oscilloscope.

RF Direct Sampling System

The IC-7300 employs an RF direct sampling system. RF signals are directly converted to digital data and processed in the FPGA (Field-Programmable Gate Array), making it possible to simplify the circuit construction.

This system is a leading technology making an epoch in amateur radio.

New “IP+” Function

The new “IP+” function improves 3rd order intercept point (IP3) performance. When a weak signal is received adjacent to strong interference, the AD converter is optimized against signal distortion.

Class Leading RMDR (Reciprocal Mixing Dynamic Range) and Phase Noise Characteristics

The IC-7300’s RMDR is improved to about 97dB* (typical value) and Phase Noise characteristics are improved by about 15dB (at 1 kHz frequency separation) compared to the IC-7200.

The superior Phase Noise characteristics reduce noise components in both receive and transmit signals.
* At 1 kHz frequency separation (received frequency: 14.2MHz, MODE: CW, IF BW: 500Hz)

Large Touch Screen Colour TFT LCD

The large 4.3-inch color TFT touch LCD offers intuitive operation. Using the software keypad of the touch screen, you can easily set various functions and edit memory contents.

Multi-Dial Knob for Smooth Operation

The combination of the multi-dial knob and the touch screen offers quick and smooth operation. When you push the multi-dial knob, menu items are shown on the right side of the display.

You can select an item with a touch of the screen and adjust levels by turning the multi-dial knob.

SD Memory Card Slot for Saving Data

The IC-7300 can store various contents in an SD card such as received and transmitted audio, voice memories, RTTY/CW memories, RTTY decode logs and captured screen images.

Personal and firmware updating data can also be stored on the SD card for easy setting.

15 Discrete Band-Pass Filters

The IC-7300 has 15 discrete RF band-pass filters.

The RF signal is only passed through one of the band-pass filters, while any out-of-range signals are rejected. High Q factor coils are used to minimize the loss in the RF band-pass filters.

Built-In Automatic Antenna Tuner

The antenna tuner memorizes its settings based on your transmit frequency so that it can rapidly tune when you change operating bands. The Enforced Tuning function* allows a wide range of temporary antennas to be tuned.

* Do not use the Enforced Tuning function except in case of an emergency. Transmission power may be reduced.

Superior Sound Quality

To offer superior sound quality, a new speaker unit has been incorporated and allocated dedicated space in the aluminum die-cast chassis.
