Amateur radio transceiver From Wikipedia, the free encyclopedia
The ICOM IC-905 is a multimode VHF/UHF/SHF portable amateur radio transceiver. 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][4] With the radio unit being 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.[5] The IC-905 uses a built in GPS receiver to stabilize its frequency and time base.[6] It has been noted that 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 and not Japan.[4] The unit supports up to four external antennas (one being for GPS reception) and has built in support for wired Ethernet, 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 will be a useful feature for mobile contesters.[7]
