Icom IC-705 HF/VHF/UHF All Mode Portable QRP 5W/10W Transceiver – A Full In-Depth Review

The Icom IC-705 is a game-changer in the world of portable ham radios. Designed for amateur radio operators who want an all-in-one, travel-friendly transceiver without sacrificing performance or features, the IC-705 is a highly compact and sophisticated rig that brings together the best of Icom's technology into a lightweight and versatile package. Covering HF, VHF, and UHF bands with all-mode operation—including SSB, CW, RTTY, AM, FM, and D-STAR digital voice—the IC-705 is ideal for portable, QRP, and even base station use in a pinch.

Design and Build Quality

Right out of the box, the IC-705 impresses with its robust and polished design. It’s compact enough to fit in one hand but feels incredibly sturdy. The transceiver weighs approximately 2.4 pounds (1.1 kg), making it a comfortable companion for field operations, SOTA (Summits on the Air), and POTA (Parks on the Air). The build is dominated by a large 4.3-inch color touchscreen display which serves as the centerpiece for user interaction.

The layout of controls is clean and intuitive. The front panel sports a combination of physical buttons and knobs, augmented by the touchscreen, providing a user-friendly interface that blends traditional and modern controls. The top and side panels house connections for antenna, microphone, power, and accessories, all well-marked and easily accessible.

Band Coverage and Power Output

The IC-705 offers wideband receive coverage from 0.030 to 144 MHz and 430–450 MHz, allowing users to monitor a broad spectrum of frequencies. On transmit, the radio covers the amateur bands on HF (160 to 10 meters), VHF (2 meters), and UHF (70 centimeters). Power output is selectable between 0.5W to 5W on internal battery and up to 10W when using an external 13.8V power supply. This makes it perfect for QRP enthusiasts while still providing enough punch for solid contacts in favorable conditions.

Despite being a QRP radio, the IC-705 performs remarkably well in signal strength and clarity. It utilizes Icom's RF direct sampling system for HF and IF sampling for VHF/UHF, minimizing signal loss and maximizing efficiency. The receiver is sensitive, with low noise, and capable of handling crowded band conditions with ease.

Display and Interface

The large color touchscreen is a standout feature of the IC-705. It offers vibrant visuals, quick response times, and easy navigation. Touch access to frequency settings, menus, and scope features adds a layer of convenience that is rarely found in portable rigs. The real-time spectrum scope and waterfall display provide a clear, high-resolution view of band activity, which is invaluable during portable operations.

The screen also displays SWR, power output, voltage, and a wide array of operational parameters, making it easy to monitor performance in the field. Menu navigation is logical and organized, and once a user becomes familiar with the system, adjustments can be made quickly and accurately.

Connectivity and Features

The IC-705 is loaded with connectivity options. It includes built-in Wi-Fi, Bluetooth, GPS, and a microSD card slot. The Wi-Fi feature allows for remote operation via Icom’s RS-BA1 app, and the Bluetooth can be used for wireless headsets and audio accessories. The built-in GPS enables automatic grid locator updates and location stamping for logs.

Another welcome inclusion is the USB-C port, which handles data communication, audio, and even power, making it compatible with modern computing equipment and simplifying digital mode operation. The radio is compatible with a wide array of digital modes such as FT8, PSK31, and RTTY when connected to a computer.

Battery and Portability

The IC-705 comes with the BP-272 Li-ion battery pack, which is also used in Icom’s handheld radios. While this is a convenient option, the battery life depends heavily on usage. Operating with full screen brightness and high transmit rates will drain the battery faster than expected, but under average portable operation, the battery holds up respectably.

Field operators will likely want to bring extra battery packs or use an external power supply to extend operation time. Despite this, the portability of the IC-705 makes it a preferred option for those who enjoy operating from remote locations.

Audio and Performance

The IC-705 delivers excellent audio quality both on transmit and receive. The internal speaker produces clear and loud sound, even in outdoor conditions. For those who want higher fidelity or need to operate discreetly, a headphone jack and Bluetooth audio compatibility are available.

On-air reports often highlight the clarity and punch of the transmitted audio. The built-in microphone is good, but Icom also offers optional mics for those wanting different configurations. The combination of clean transmission, sensitive reception, and advanced DSP filtering ensures strong performance even under challenging band conditions.

Logging and SDR Capabilities

Another feature worth highlighting is the SDR-like performance of the IC-705. With its direct sampling receiver and comprehensive real-time band scope, the radio mimics many of the capabilities found in full-size SDR transceivers. This is especially useful for those who are serious about monitoring multiple signals, spotting weak signals, and adjusting operating strategies in real-time.

Logging is made easier with the internal GPS and the ability to store logs on a microSD card. This helps simplify post-operation analysis or uploading to digital logging platforms.

Final Thoughts

The Icom IC-705 is a near-perfect companion for the modern ham radio operator who values portability, versatility, and technology. While it does come with a premium price tag, it more than justifies the cost with its wealth of features, performance capabilities, and cutting-edge technology packed into a compact chassis.

Whether used for portable QRP operations, base station backup, digital modes, or simply casual listening across the bands, the IC-705 stands out as a top-tier transceiver. It bridges the gap between handheld convenience and desktop functionality, making it one of the most innovative and desirable radios in the amateur radio market today.
