The Icom IC-703 Plus all-mode transceiver is designed for efficient QRP operation across HF bands (160-10 meters) and 6 meters, offering output power settings of 10, 5, 2.5, 1, or 0.5 watts. This model stands out for its energy efficiency, drawing only 300 mA in standby mode, significantly less than the two amps typical of many competing radios. Built-in features often incur additional costs in other models, including an automatic antenna tuner, AF DSP, a memory keyer, and a TCXO with a precision of ± 0.5 ppm. The device has a large, high-contrast, backlit LCD that enhances visibility and usability.

User experience is further enhanced by an intuitive menu system that customises various operational aspects. The IC-703 Plus supports advanced features such as an IF shift, an AF speech compressor, a spectrum scope, and an SWR analyzer, making it a versatile tool for amateur radio enthusiasts. The transceiver also supports four types of scanning, ensuring that users can efficiently monitor their desired frequencies. The transceiver includes essential accessories such as the OPC-1229 DC power cable, spare fuses, key plugs, an accessory cable, and the HM-103 hand microphone.

Additional capabilities of the IC-703 Plus include general coverage receive, alpha memories, RIT, preamp/ATT, VFO A/B, and a 1 Hz display. Users can use features like DSP auto notch, noise reduction, and a menu-configurable interface that can be set to simple or advanced mode. The transceiver boasts 105 memories, an auto-scaling power meter, a removable head, an S/RF meter, a mini-spectrum scope, and an electronic memory keyer. It is a comprehensive solution for casual operators and serious hobbyists alike.
