Introducing the Icom IC-905 VHF/UHF/SHF All Mode Transceiver – your gateway to an exciting new world in the SHF band. With its industry-first 144 / 430 / 1200 / 2400 / 5600 MHz and 10 GHz* coverage, this all-in-one transceiver offers unparalleled versatility and performance.

The IC-905 is designed with ICOM’s cutting-edge technology, a spirit of challenge, and a playful mind, making it a standout choice for amateur radio enthusiasts. It consists of a controller and an external RF unit, with the RF technology housed separately to minimize losses via long coaxial cables.

The controller of the IC-905 inherits the sleek look and user-friendly operation of the popular IC-705. The RF unit, on the other hand, is mounted externally on the mast near the antennas, ensuring optimal signal quality. Both components are connected via a weatherproof Ethernet cable that not only transmits control signals but also supplies power using the widely adopted “Power over Ethernet” standard. This eliminates power losses on the cable and enhances efficiency.

The HF unit of the IC-905 is weatherproof (IPX 5) and equipped with advanced transmit and receive technology for the 2 m, 70 cm, 23 cm, 13 cm, and 6 cm bands. Additionally, it features a built-in GPS receiver that stabilizes the frequency of the integrated OCXO for exceptional accuracy and stability at higher bands. Transmitting power on the 2 m, 70 cm, and 23 cm bands is a reliable 10 Watts each, utilizing a common N-socket antenna connector. For the 2400 and 5600 MHz bands, there are separate SMA socket antenna connectors, offering 2 Watts of power each. Moreover, the IC-905 can seamlessly operate on the 10 GHz band through the addition of the optional CX-10G HF unit, which is also weatherproof and easily attached to the mast. With a transmitting power of 500 mW on 10 GHz, you’ll experience reliable long-range communication.

The IC-905’s control unit features a vibrant 4.5-inch color touch display that mirrors the user-friendly interface of the IC-705. You’ll enjoy the convenience of spectrum and waterfall displays with adjustable bandwidths, offering a visual representation of signals for precise tuning and monitoring.

Operating at a voltage of 13.8 V, the IC-905 generates the necessary 48 V for the RF unit’s power supply internally, simplifying setup and reducing cable clutter. It also provides an Ethernet port for seamless integration into your radio station setup, while an optional SD memory card allows you to store configuration data, memories, images, and other valuable data. For local PC connectivity, utilize the USB-C socket.

With the included weatherproof Ethernet cable, connecting the controller to the RF unit is a breeze. Get ready to elevate your amateur radio experience with the Icom IC-905 VHF/UHF/SHF All Mode Transceiver – the ultimate companion for exploring new horizons in the SHF band.

*Note: 10 GHz coverage requires the optional CX-10G HF unit.
