Icom IC-705 — In-Depth Review
Overview
The Icom IC-705 is a compact, feature-rich portable SDR transceiver that brings many elements of a base station into a backpack-friendly package. It covers HF, 6m, 2m and 70cm, supports voice and data modes including D-STAR, has a large 4.3” touchscreen, built-in GPS, Bluetooth, and Wi-Fi, and runs on an internal 7.4 V lithium battery for genuine field portability. Output from the internal battery is QRP (about 5 W), rising to roughly 10 W when powered from a 13.8 V external supply. This flexible design makes it ideal for Summits-on-the-Air, Parks-on-the-Air, portable contesting, or emergency communications.
Key Specifications
• Frequency coverage: HF through 6 m and VHF/UHF amateur bands with wideband receive coverage.
• Output power: About 5 W on the internal battery; up to 10 W on external power.
• Receiver architecture: RF direct sampling below 25 MHz with downconversion sampling above.
• Display: 4.3” color touch screen with real-time spectrum scope and waterfall.
• Interfaces: Bluetooth, Wi-Fi, USB for audio/data, GPS built in.
Design, Ergonomics and Build Quality
Out of the box, the IC-705 feels premium and well-engineered. It is compact yet dense, offering the durability needed for field work. The knobs and buttons feel solid, and the touchscreen is responsive and intuitive. It’s portable enough to carry, but not an ultralight hiking radio—it’s better described as a portable base station. The control layout is thoughtful, with essential knobs easily accessible and menus organized efficiently. The unit’s case feels rugged, capable of handling outdoor conditions.
User Interface and Display
The 4.3-inch color touchscreen is one of the main attractions of the IC-705. It delivers a bright, crisp spectrum scope and waterfall display that makes tuning across bands simple and visually engaging. Navigating through menus is straightforward, with most key functions accessible in a few taps. Despite its modern interface, the radio retains physical tuning and multi-function knobs, which are appreciated when operating outdoors or wearing gloves. The mix of touchscreen and manual controls makes it versatile in any environment.
Receiver Performance
The IC-705’s receiver delivers low noise, good sensitivity, and impressive selectivity for a radio of its size. The SDR-based design gives it clear, stable audio and excellent signal handling. The spectrum scope helps identify signals quickly and efficiently. For most HF and VHF/UHF use, the receiver holds its own against larger base stations. Some operators may notice slightly higher noise levels in electrically noisy environments, but overall, performance is strong for portable use and QRP operation.
Transmitter and Power Considerations
At 5 watts on the internal battery and around 10 watts with external power, the IC-705 is a true QRP-class transceiver. It is well-suited for low-power enthusiasts and field operators who value efficiency and portability. The transmitted audio is clear and strong within its power range. For those wanting higher output, pairing it with a small external amplifier is an option. The radio’s clean modulation and stability make it reliable for both voice and digital operation.
Battery Life and Portability
The internal 7.4 V lithium-ion battery gives real independence for portable operation. Runtime varies depending on usage—casual SSB or CW operation yields several hours, while heavy digital operation will shorten it. Operators who spend long hours in the field often carry an external battery or power supply for extended use. The ability to switch between 5 W and 10 W depending on power source gives flexibility in the field.
Digital Modes, Connectivity and Accessories
Connectivity is a strong point of the IC-705. Built-in Bluetooth, Wi-Fi, and GPS open many possibilities. It can connect directly to a computer, tablet, or smartphone for digital modes such as FT8 or Winlink without the need for an external interface. GPS integration supports location-aware operations and D-STAR features. A variety of accessories are available, including the Icom AL-705 magnetic loop antenna and carrying cages that protect the radio during travel. Firmware updates occasionally add features, making it a continually improving rig.
Common Criticisms and Limitations
• No built-in antenna tuner, requiring an external tuner or resonant antennas for band changes.
• Limited power output of 5–10 W, which may be insufficient for some operators.
• Higher price point compared to some other portable transceivers.
These are reasonable trade-offs for a device that offers such broad frequency coverage, SDR performance, and advanced connectivity in a single portable unit.
Who Should Buy the IC-705
The Icom IC-705 is best for radio operators who want a highly capable all-mode portable transceiver that can handle HF, VHF, and UHF without compromise. It’s especially suited for operators who enjoy field operation, emergency communication setups, or want a compact but feature-rich radio station. It’s also a great option for those who enjoy experimenting with digital modes and remote control operation.
Final Verdict
The Icom IC-705 is one of the most advanced portable QRP transceivers available. It successfully combines base-station performance with portable convenience. With an excellent receiver, strong build quality, wide connectivity, and user-friendly interface, it stands out as a top-tier choice for serious field operators and experimenters. While it lacks an internal tuner and higher output power, the IC-705’s flexibility, modern features, and reliability make it one of the best all-around portable radios on the market today.
