Icom IC-7300 100W HF/50MHz SDR Transceiver

What bands does the Icom IC-7300 cover?
The Icom IC-7300 covers all major amateur radio High Frequency (HF) bands from 160 meters through 10 meters, plus the 50 MHz (6-meter) band, delivering up to 100 watts of RF output power.

Does the Icom IC-7300 have a built-in antenna tuner?
Yes, the IC-7300 features a fast, built-in automatic antenna tuner (ATU). It is designed to match antennas with a Standing Wave Ratio (SWR) of up to 3:1 on HF bands, and includes an "Enforced Tuning" mode for emergency operation on higher-SWR antennas.

What is the Yaesu equivalent to the Icom IC-7300?
The three primary Yaesu transceivers compared against the IC-7300 are:

• Yaesu FT-710: The most direct and modern competitor, featuring an updated SDR architecture.
• Yaesu FT-DX10: A higher-end hybrid SDR transceiver offering superior narrow-band receiver selectivity.
• Yaesu FT-991A: An all-in-one shack option that includes VHF and UHF coverage alongside HF.

Is there a successor to the Icom IC-7300?
Yes! The official successor is the Icom IC-7300MK2, which updates the original SDR platform with modern connectivity options (like built-in HDMI, USB-C, and native LAN for remote operation) while maintaining the intuitive touch-screen workflow.

Where are Icom radios manufactured?
All genuine Icom amateur radio equipment is designed and manufactured exclusively at Icom's production facilities in Japan, ensuring high standards of quality control.

How do I update the IC-7300 firmware, and where do I download it?
You can download official firmware updates directly from Icom's official support portal. To install, save the .dat file onto a formatted SD card, insert it into the radio, and go to MENU > SET > SD Card > Firmware Update.

What does "OVF" mean, and how do I fix a "deaf" or overloaded receiver?
OVF stands for "Overflow," meaning strong adjacent signals are overloading the analog-to-digital converter (ADC). To resolve OVF or clear receiver desensitization, press the RF/SQL control or enable the ATT (Attenuator)/lower the P.AMP (Preamp) setting until the indicator disappears.

What is the "GENE" button on the display?
Tapping "GENE" (short for General Coverage) allows you to tune freely across the entire HF spectrum (0.030–74.800 MHz) for shortwave listening, outside of standard ham band segments.

Why does the real-time clock reset on my IC-7300?
The IC-7300 uses an internal rechargeable battery/capacitor to power the clock module. If the radio is unplugged from its main power supply for extended periods, this cell drains. To recharge it, leave your 13.8V power supply connected to the radio (power switched off on the radio panel) for approximately 48–72 hours.

How do I stop RF feedback on my USB audio/CI-V line?
Because HF RF energy can couple onto external cabling during transmission, use a high-quality, double-shielded USB cable equipped with type-31 or type-43 ferrite chokes near both ends of the cable to eliminate digital audio drops or command resets.

How do I save and restore my custom settings?
Insert a formatted SD card (up to 32GB SDHC) into the front slot, then navigate to MENU > SET > SD Card > Save Setting to store your memory channels, display preferences, and filter configurations.
