FEATURES

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

• Real-Time Spectrum Scope

The spectrum scope is class-leading in resolution,

sweep speed and dynamic range. When you touch the scope screen on the intended signal, the touched area is

magnied. The large 4.3 inch color TFT touch LCD offers

intuitive operation.

• New “IP+” Function

The new IP Plus 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 and Phase Noise

Characteristics

The RMDR is improved to about 97dB (typical value) and

Phase Noise characteristics are also improved about 15dB (at 1 kHz frequency separation) compared to the IC-7200.

• A 4.3 inch touch screen color display

• A built-in automatic antenna tuner

• Multi-function control for easy settings

Selecting a location

Select a location for the transceiver that allows adequate air circulation, free from extreme heat, cold or vibrations, and other electromagnetic sources.

The transceiver has a stand for desktop use.

Stand

CAUTION: NEVER carry the transceiver by holding the stand, dials, controls and so on. This may damage them.

Heat dissipation

• DO NOT place the transceiver against walls or put anything on top of the transceiver. This may block

airow and overheat the transceiver.

• NEVER install the transceiver in a place without adequate ventilation. Heat dissipation may be reduced, and the transceiver may be damaged.

• DO NOT touch the transceiver after transmitting continuously for long periods of time. The transceiver may become hot.

Grounding

To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other problems, ground the transceiver using the ground terminal [GND] on the rear panel.

For best results, connect a heavy gauge wire or strap to a long ground rod. Make the distance between the [GND] terminal and ground as short as possible.

BASIC OPERATION

About the 5 MHz frequency band operation (USA version only)

Operation on the 5 MHz frequency band is allowed on 5 discrete frequencies and you must adhere to the following:

• The USB, USB Data, PSK, and CW modes.

• Maximum of 100 watts ERP (Effective Radiated

Power)

• Maximum 2.8 kHz bandwidth

It is your responsibility to set all controls so that transmission in this frequency band meets the stringent conditions under which amateur operations may use these frequencies.

TIP: We recommend that you save these frequencies, modes and lter settings into memory channels, for easy recall.

NOTE: To assist you in operating within the rules specied by the FCC, transmission is illegal on any frequencies other than the ve shown in the tables below.

For the USB and USB data modes:

The FCC species center frequencies on the 5 MHz frequency band. However, the transceiver displays carrier frequency. Therefore, tune the transceiver to 1.5 kHz below the specied FCC channel center frequency.

out and it gives you better audio quality.

• SOFT

The lter shoulders are roundly formed as in analog

About the SD card Saving data onto the SD card

The SD and SDHC cards are not supplied by Icom. User supplied.

You can use an SD card of up to 2 GB, or an SDHC of up to 32 GB. Icom has checked the compatibility with the following

SD and SDHC cards.

(As of April 2016)

Brand Type Memory size

SD 2 GB

4 GB

SanDisk

SDHC

8 GB 16 GB 32 GB

L The above list does not guarantee the card’s

performance.

L Throughout the rest of this document, the SD card

and an SDHC card are simply called the SD card or the card.

TIP: Icom recommends that you save the transceiver’s

factory default data for backup. (p. 8-4)

NOTE:

• Before using the SD card, thoroughly read the card’s instructions.

• If you do any of the following, the card data may be corrupted or deleted.

- You remove the card from the transceiver while the

card is being accessed.

- A power failure occurs or the power cable is disconnected while the card is being accessed.

- You drop, impact or vibrate the card.

• Do not touch the contacts of the card.

• The transceiver takes a longer time to recognize a high capacity card.

• The card will get warm if continuously used for a long

period of time.

• The card has a certain lifetime, so data reading or writing may not be possible after using it for a long period. When reading or writing data is impossible, the card’s lifetime has ended. In that case, use a new one. We recommend you make a separate backup le of the important data onto your PC. (p. 8-8)

• Icom will not be responsible for any damage caused by data corruption of a card.

You can save the following data onto the card:

• Data settings of the transceiver Memory channel contents saved in the transceiver.

• Communication content The transmitted and received audio.

• Communication log The communication and receive history log.

• Voice audio for the Voice TX function

Voice audio to use with the Voice TX function.

• RTTY decode log The transmitted or received RTTY decode history log.

• Captured screens
