10kHz to 3GHz Super Wideband Coverage
The IC-R8600 decodes various digital protocol signals including P25 (Phase 1), NXDN™, dPMR™, D-STAR, Japanese DCR (Digital Convenience Radio) as well as receives conventional analog signals such as USB, LSB, FSK, CW, AM, S-AM (Synchronous-AM), FM and WFM modes, covering 10kHz to 3GHz wideband in 1Hz steps.
Absolute Value of RSSI (Received Signal Strength Indicator)
The IC-R8600 shows S-meter, dBμ, dBμ (emf) and dBm meter types in the RSSI. The dBμ, dBμ (emf) and dBm meter has a high ±3dB accuracy* (between 0.5–1100MHz) that can be used for measuring signal strength level.
* Less than ±6dB between 1100–3000MHz.
Software Demodulation in FPGA Processing
The IC-R8600 utilizes FPGA (Field Programmable Gate Array) and DSP units for demodulation, decoding and most of signal processing. Direct HF signals and intermediate frequency signals, which are converted from VHF/UHF signals, are digitized in a 14-bit A/D converter and transferred to the FPGA and DSP for optimal processing. The high-rate 122.88MHz sampling frequency used for the A/D converter results in superior aliasing and image reception reduction.
Superb Receiver Performance
The IC-R8600 has 11 discrete RF bandpass filters in the HF bands and 13 bandpass filters in the VHF/UHF bands. To prevent overflow, only the intended signal is passed, while any out of range strong interference signals are rejected. The IC-R8600 provides +30dBm IP3 and 105dB dynamic range at 14.1MHz. IP3 performance is +10dBm at 144MHz and 0dBm at 440MHz.
Ample Memory Channels
The IC-R8600 has up to 2000 regular memory channels assignable to 100 groups. In addition to the regular memory channels, up to 100 scan skip channels and 50 pairs of program scan edges can be set. The auto memory write scan automatically stores busy frequencies in the auto memory write channels (up to 200 channels). These memory channels and various settings can be edited with the optional CS-R8600 programming software on a Windows® PC.
Variety of Scan Functions
A variety of scan functions effectively and thoroughly search for desired stations. The IC-R8600 scans up to 100 channels per second in the memory scan mode.
・ Program scan/Fine program scan
・ ⊿f scan/⊿f fine scan
・ Priority scan
・ Memory scan
・ Selected memory scan
・ Selected mode memory scan
・ Auto memory write scan
Real-time Spectrum Scope with Waterfall Function
The high-resolution real-time spectrum scope provides class-leading performance in resolution, maximum 30 frames per second* fast sweep speed, ±2.5MHz wide scope span (display range) and 110dB of dynamic range (at ±2.5kHz span). The waterfall screen allows you to find weak signals by showing the spectrum change over time. When tapping the spectrum scope or waterfall screen, the tapped area can be selected as the operating frequency. The peak search function finds several peak frequencies within the scope range, and helps you to select these. (* Approximate)
Quick, Smooth and Intuitive Operation
To efficiently acquire intended signals, the IC-R8600 user interface provides quick and accurate operation. The large 4.3-inch color display, with touch screen function, is configured to collect operating information. By tapping indications and icons on the screen, the setting menu will pop up and parameters can easily be adjusted. When either the DIAL A, B or C multi-function control knobs is pushed, various functions, such as scan speed, RF gain, audio tone, display backlight or other menus will pop up on the display.
SD Card Slot for Receiver Recorder
The recorder function can record received audio onto an SD card in WAVE format. The recorded voice audio can be played back on the receiver or a PC. When a 32GB SD card is used, up to 270 hours of recording is possible. In addition, the screen capture function saves a snap shot of the screen in PNG or BMP format on the SD card.
* An SD card is required separately.
Remote Control Function through IP Network or USB Cable
The optional RS-R8600 PC remote control software allows you to listen to received audio and control most of the receiver functions, including the spectrum scope, through an IP network or USB cable.
I/Q Signal Output
The I/Q signal output function* enables you to derive digital IF signals from the I/Q output port to a PC through a USB cable. It can be used for analyzing spectrum or decoding signals. The IC-R8600 outputs I/Q data to the third-party software HDSDR, and the IC-R8600 can be controlled by the HDSDR. The optional RC-28 USB remote encoder provides a hardware dial for realistic dial operation.

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|
