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] Additionally 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]
