ICOM IC-905

The ICOM IC-905 is a multimode VHF/UHF/SHF portable amateur radio transceiver.

About

The radio has between 10 and 0.5 watts of transmitter output, depending on the frequency selected.[1]

The radio was announced by ICOM on 22 August 2022 at the Tokyo Ham Radio Fair in Japan.[2]

The IC-905 has support for a wide variety of commonly used amateur radio modes, including the Japan Amateur Radio League's digital voice mode, DSTAR.[3]

The form factor of the control head for the IC-905 is similar to that of the IC-705, and includes its large screen and spectrum scope.[3] The radio unit is remotely controlled from a distance in order to reduce loss over long coax cable runs. This is an important adaptation for this radio system, as losses increase with the frequency being used.[4] The IC-905 uses a built-in GPS receiver to stabilize its frequency and time base.[5] The IC-905 has a wide range of frequencies, but lacks the 222MHz and 902MHz amateur bands, as these are only available in North America.[6] The unit supports up to four external antennas (one being for GPS reception), and has built-in support for wired Ethernet and USB Type C, and an SD card reader.[7] The addition of a USB connector allows users to connect their computers to the IC-905 for running digital data modes such as PSK31, or FT8. The integration of Ethernet support is a useful feature for mobile contesters.[7]
