Description

Explore the World of Microwave with 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 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 band-width 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 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 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.
