IC-905

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 in SSB, AM, FM, D-STAR DV/DD, and FM-TV (Amateur TV) is possible. 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 centimetres rather than metres, keeping 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 ageing. 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 Centre, 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 analogue camera connected, the IC-905 can transmit and receive real-time video. Furthermore, received videos can be shown on the display with composite video input.

Icom Common User Interface
The controller of the IC-905 was designed based on the compact IC-705 and utilises Icom’s Common User Interface system used in Icom’s touchscreen 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 CX-10G 10 GHz Transverter
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.
