Now, a serious spectrum scope is NOT a “privilege” of high-grade models. The high-resolution real-time spectrum scope comes loaded with the IC-7300. Its real-time spectrum scope with waterfall function provides top-level performance in resolution, sweep speed and dynamic range.

Instead of the conventional superheterodyne system, the IC-7300 utilizes the RF direct sampling system — a first in an amateur radio transceiver. This technology is seen in Software Defined Radios and other radio equipment. RF signals are mostly processed through the FPGA (Field-Programmable Gßate Array), making it possible to eliminate physical mixer and filter devices and offer a high performance real-time spectrum scope in a compact body.
* Researched by Icom, among major amateur radio manufactures.
Overcoming cost and performance limitations of the superheterodyne system, the RF direct sampling system pursues ideal high performance phase noise. As the result, compared to the IC-7200, the IC-7300’s phase noise characteristics are improved about 15dB (at 1kHz frequency offset). This superior phase noise reduces noise components in both receive and transmit signals.

The IC-7300 has a large color TFT LCD and it can be used as a touch screen. This user-friendly interface provides intuitive operation. Using the software keypad of the touch screen, you can easily set various functions and edit memory contents.
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. This combination of the multi-dial knob and touch screen offers quick and smooth operation.
The high-speed automatic antenna tuner is built into a compact chassis (240 (W) × 238 (D) × 95 (H) mm; 9.45 × 9.37 × 3.74 in). You can easily carry the radio and enjoy field operation.
To offer optimum sound quality, a new speaker unit is employed and is allocated sufficient space in the aluminium die-cast chassis.
