The built-in antenna tuner memorizes its settings based on your transmit frequency, so that it can rapidly tune when you change operating bands. High Q factor coils are used to minimize the loss in the RF band-pass filters. The RF signal is passed through only one of the band-pass filters, while any out of range signals are rejected. IC-7300's have 15 discrete RF band-pass filters. The superior Phase Noise characteristics reduce noise components in both receive and transmit signals. IC-7300 transceivers' RMDR is improved to about 97dB (typical value) and Phase Noise characteristics are improved about 15dB (at 1 kHz frequency separation) compared to the IC-7200. When a weak signal is received adjacent to strong interference, the AD converter is optimized against signal distortion. The new "IP-plus" function improves 3rd order intercept point (IP3) performance. This system is a leading-edge technology creating a new era in amateur radio.

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. IC-7300 transceivers employ an RF direct-sampling system.

Using the software keypad of the touch screen, you can easily set various functions and edit memory contents. color TFT touch LCD offers intuitive operation. Either transmit or receive audio may be displayed on the FFT scope, with the waterfall function and the oscilloscope. 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. The waterfall function shows a change of signal strength over a period of time and allows you to find weak signals that may not be apparent on the real-time spectrum scope. The combination of the waterfall function and the real-time spectrum scope assists in maximum receive performance of IC-7300 radios and increases QSO opportunities without missing weak signals. A second touch of the scope screen changes the operating frequency and allows you to accurately tune to the desired signal. When you first touch the scope screen around the intended signal, the touched part is magnified. While listening to received audio, you can check the real-time spectrum scope and quickly move to another signal.
