amateur radio Amateur radio, also known as ham radio, is the use of the radio frequency radio spectrum, spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emer ...

transceiver In radio communication, a transceiver is an electronic device which is a combination of a radio ''trans''mitter and a re''ceiver'', hence the name. It can both transmit and receive radio waves using an antenna, for communication purposes. The ...

. The radio has 5 watts of output when using its internal battery and 10 watts of output when using external power. 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. The IC-705 has support for a wide variety of commonly used amateur radio modes including ICOM's proprietary digital voice mode

D-STAR D-STAR (Digital Smart Technologies for Amateur Radio) is a digital voice and data protocol specification for amateur radio. The system was developed in the late 1990s by the Japan Amateur Radio League and uses minimum-shift keying in its pack ...
