ICOM IC-705
Amateur radio transceiver
From Wikipedia, the free encyclopedia
The ICOM IC-705 is a multimode HF/VHF/UHF portable amateur radio transceiver. The radio has 5 watts of output when using its internal battery and 10 watts of output when using external power.[1] With the rise in award programs such as Summits on the Air and Parks on the Air, this lightweight fully functional radio is a popular choice for people using them in the field.[2][1] The IC-705 has support for a wide variety of commonly used amateur radio modes, including ICOM's proprietary digital voice mode, D-STAR.[3] The IC-705 is also one of the first mainstream amateur radios to use SDR technology instead of the older superheterodyne design.[4] The IC-705 has multiple extra features that are useful when operating in the field. Supporting the radio's D-STAR module is a GPS receiver to allow users to send their location though the D-STAR network, as well as help locate nearby repeater systems.[2] In addition to the GPS receiver, the radio supports 2.4 GHz Wi-Fi, which allows users to connect their computers or tablets to the IC-705 for running digital data modes such as PSK31, Winlink, and FT8.[5][6]

The radio has been praised for its size, easy-to-use menus, large easy-to-read screen and the quality of its build.[1][7] Common criticisms of the radio include its lack of a built-in antenna tuner and its price, compared to other more powerful radios on the market.[8][9]
