The controller head can be separated from the main unit. A duty-cycle control setting further reduces current consumption in stand-by mode. A LCD backlight timer setting also controls the LCD backlighting depending on the power supply voltage. When ¡§Auto¡¨ is selected, the IC-703 automatically detects the power supply voltage and reduces the current consumption while operating with the external battery pack (or less than 11V power source). To save power consumption, the IC-703 has a current consumption control setting.

The IC-703 and the battery can be packed into the carrying case, LC-156, making the IC-703 a go anywhere portable rig. The optional 9.6V, 2800mAh Ni-Cd battery pack provides up to 8 hours of operating time at 5W output. The power meter automatically adjusts its measurement range according to the max. Precise maximum output power settings (10/5/2.5/1/0.5W) are selectable, instead of hi/low only power settings. The IC-703 provides excellent sound reproduction of both faint and strong signals even in crowded band conditions. The IC-703 achieves a high sensitivity of 0.16µV* in SSB, CW and RTTY modes within HF bands, on par with that of a base station transceiver. The IC- 703 provides 5W output (2W in AM mode), while operating at 9.6V DC (9.6V¡V11V) or with the optional battery pack. Newly developed PA unitĪ stable 10W output power (4W in AM mode) is provided by the newly designed PA unit, when 13.8V DC is supplied. The automatic notch cuts beat interference which is useful for FM and SSB operation. The noise reduction function helps pick out the signal buried in noise. The built-in DSP unit provides superior receive performance. A built-in antenna tuner eliminates the need to carry one with you.
Latch relays are used in the antenna tuner to greatly reduce the power consumption.
Field and mobile operation are made simple and efficient, especially when using a short length antenna covering narrow bandwidth. The antenna tuner covers 1.8MHz to 54MHz. The IC-703 has an automatic antenna tuner built in to its compact body. This is ideal radio for the foundation licensee, QRP enthusiast or any Radio Amateur who wants a convenient HF portable unit. A built-in antenna tuner, built-in DSP unit, 10W of output power, an optional external battery pack and carrying case for portable operation allow the IC-703 to have base station ability with all the portable convenience of a mobile rig. In the world of HF/50MHz portable communications, the IC-703 incorporates all the practicality and technical expertise of the IC-706MKIIG, but does so with an emphasis on portability and economy.
