Industry First Multi-Band 144 MHz to Microwave Transceiver!
Explore the World of Microwave
The IC-905 is the industry’s first microwave rig in the 144, 430, 1200, 2400, 5600 MHz and 10 GHz* bands. Multi-mode operation including SSB, CW, AM, FM, RTTY, D-STAR DV/DD, and FM-TV (Amateur TV). Output power is 10 W on 144, 430, 1200 MHz, 2 W on 2400, 5600 MHz, and 0.5 W on 10 GHz.
* CX-10G is required for 10 GHz operation.
Separate Controller and RF Unit Configuration
The IC-905 is the industry’s first super efficient microwave base station with the RF unit designed to be at the base of the antenna, rather than in the shack. This design eliminates signal loss due to costly, long coax feed line runs found in legacy SHF designs. Optional 50 m (164 ft) or 20 m (65.6 ft) controller cable is available with the IC-905.
Less Signal Cable
With the RF unit mounted at the antenna, transmit and receive signals are at their maximum efficiency as the coax feed line is measured in centimeters rather than meters, keep signal loss to a minimum. This is possible due to the controller cable providing digital communications between the controller and RF units.
Power Supplied through the Controller Cable
The DC power is supplied from the controller to the RF unit through the controller cable, making it possible to supply power with a low loss. Moreover, optional CX-10G’s power is supplied from the IC-905 RF unit.
Less Cable Loss than Coaxial Cable
With the RF unit mounted at the antenna, transmit and receive signals are at their maximum efficiency as the coax feed line is measured in inches rather than feet, keep signal loss to a minimum. This is possible due to the controller cable providing digital communications between the controller and RF units.
GPS-Controlled Oscillator for Ultimate Frequency Stability
Frequency accuracy and stability are required for SHF band operation. Even with a high-performance OCXO, the frequency gradually changes due to temperature and aging. To solve this problem, the IC-905 uses a high-precision 1 pulse-per-second (1 PPS) clock signal from an internal GPS (GNSS) receiver to enable advanced frequency control.
Wideband 50 MHz Span
Real-time Spectrum Scope
A high-performance real-time spectrum scope and waterfall display are built in. The real-time spectrum scope can be adjusted for Center, Fixed, and Scroll
mode, and it covers a wide bandwidth of up to 50 MHz span.
ATV (Amateur TV) Mode
The IC-905 is compatible with the ATV (FM-TV, NTSC, PAL or SECAM) mode. With an analog camera connected, the IC-905 can transmit video, and receive a real-time video. Furthermore, received videos can be monitored on an external display connected through AV-output connector.
Icom Common User Interface
The controller of the IC-905 was designed based on the compact IC-705 and utilizes Icom’s Common User Interface system used in Icom’s touch screen transceivers.
Full D-STAR Functions
DV, DD mode, DR function, Terminal mode, and Access Point mode enable easy use of D-STAR. It is also possible to send, receive, and view received pictures with the IC-905.
Optional 10 GHz Transverter, CX-10G
The CX-10G transverter provides 10 GHz operation by converting to a 2400 MHz IF signal. 10 GHz operation becomes more approachable and easier to work. The CX-10G is in bypass mode when the use of the 2400 MHz band.
A Variety of Optional Antennas
Optional Collinear antennas for 2400 MHz, 5600 MHz, and 10 GHz are available. Additionally, a high-performance parabolic antenna for 10 GHz is also available.

Ingress Protection (IP) Code
Ingress Protection (IP) ratings define the level of protection provided by enclosures to prevent the ingress of foreign objects (dust) and liquid into the electrical equipment.
International Standard IEC 60529 outlines an international classification system that describes the sealing characteristics of electrical equipment.
The classification system uses the “IP” code, or “Ingress Protection” code, to define the level of seal.
An IP number contains two numbers (i.e. IP67) in most instances which relate to the level of protection provided by an enclosure or housing.
Either number may be shown as “X” (i.e. IPX6 / IP7X) to indicate the “X” part is not tested.
Degrees of Solid Particle Protection – 1st Digit
IP6x | No ingress of dust; complete protection against contact. (Dust tight) |
---|---|
IP5x | Protected from the amount of dust that would interfere with normal operation. (Dust protected) |
Degrees of Liquid Ingress Protection – 2nd Digit
IPx8 | Protected against continuous immersion in water. Depth and duration specified by model. |
---|---|
IPx7 | Protected against temporary immersion in water for 1 m (3.3 ft) for 30 minutes |
IPx6 | Protected against water projected by powerful jets from any direction. 100 L per minute by a powerful jets (12.5 mm) for 3 minutes. |
IPx5 | Protected against water projected by jets from any direction. 12.5 L per minute by a nozzle (6.3 mm) for 3 minutes. |
IPx4 | Protected against water splashed against the equipment from any direction |
