Explore the World of Microwave with IC-905
The IC-905 is the industryās first microwave rig in the 144, 430,Ā 1200, 2400, 5600 MHz and 10 GHz* bands. Multi-mode operationĀ including SSB, CW, AM, FM, RTTY, D-STAR DV/DD, and FM-TVĀ (Amateur TV). Output power is 10 W on 144, 430, 1200 MHz,Ā 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 industryās first super efficientĀ microwave base station with the RF unit designedĀ to be at the base of the antenna, rather than in theĀ shack.Ā This design eliminates signal loss due toĀ costly, long coax feed line runs found in legacy SHFĀ designs. Optional 50 m (164 ft) or 20 m (65.6 ft)Ā controller cable is available with the IC-905.
Less Signal Cable
With the RF unit mounted at the antenna, transmitĀ and receive signals are at their maximum efficiencyĀ as the coax feed line is measured in centimeters ratherĀ than meters, keep signal loss to a minimum. This is possible due to the controller cable providing digitalĀ communications between the controller and RF units.
Power Supplied through the Controller Cable
The DC power is supplied from the controller to theĀ RF unit through the controller cable, making itĀ possible to supply power with a low loss.Ā Moreover, optional CX-10Gās power is supplied fromĀ the IC-905 RF unit.
Less Cable Loss than Coaxial Cable
With the RF unit mounted at the antenna, transmitĀ and receive signals are at their maximum efficiencyĀ as the coax feed line is measured in inches ratherĀ than feet, keep signal loss to a minimum. This isĀ possible due to the controller cable providing digitalĀ communications between the controller and RFĀ units.
GPS-Controlled Oscillator for Ultimate Frequency Stability
Frequency accuracy and stability are required for SHF bandĀ operation.Ā Even with a high-performance OCXO, the frequency graduallyĀ changes due to temperature and aging. To solve this problem, theĀ IC-905 uses a high-precision 1 pulse-per-second (1 PPS) clockĀ signal from an internal GPS (GNSS) receiver to enable advancedĀ frequency control.
Wideband 50 MHz Span –Ā Real-time Spectrum Scope
AĀ high-performance real-time spectrum scope andĀ waterfall display are built in. The real-time spectrumĀ scope can be adjusted for Center, Fixed, and Scroll mode, and it covers a wide band-width of up to 50 MHzĀ span.
ATV (Amateur TV) Mode
The IC-905 is compatible with the ATV (FM-TV, NTSC,Ā PAL or SECAM) mode. With an analog cameraĀ connected, the IC-905 can transmit video, and receiveĀ a real-time video.Ā Furthermore, received videos can be shown on theĀ display with composite video input.
Icom Common User Interface
The controller of the IC-905 was designed based on theĀ compact IC-705 and utilizes Icomās Common UserĀ Interface system used in Icomās touch screen transceivers.
Full D-STAR Functions
DV, DD mode, DR function, Terminal mode, and Access Point modeĀ enable easy use of D-STAR. It is also possible to send, receive, andĀ view received pictures with the IC-905.
Optional 10 GHz Transverter, CX-10G
The CX-10G transverter providesĀ 10 GHz operation by converting toĀ a 2400 MHz IF signal.Ā 10 GHz operation becomes moreĀ approachable and easier to work.Ā The CX-10G is in bypass modeĀ when the use of the 2400 MHzĀ band.
