ICOM R8600






Initial support added on June 26th, 2018. Available in version 3.0.1. Based on two days of use on HF and VHF this is an excellent radio!


Getting Started

Follow these steps:

  1. Download SDR Console 3.0.1 or higher.
  2. Make sure the R8600 has firmware 1.3 or higher installed (shown on the R8600 screen when you press the power button).
  3. Connect the R8600's IQ-OUT port to a USB2 or USB3 port on your PC, this is the only connection required.
  4. Install either the HDSDR driver from ICOM or the driver which comes with SDR Console (see below).
  5. Read the information on this page!

Full information is found in ICOM's document "I/Q OUTPUT REFERENCE GUIDE iR8600 COMMUNICATIONS RECEIVER" which you download from the ICOM website [link].



The R8600 uses WinUSB which is part of a standard Windows installation. To setup your R8600 to use WinUSB you must install either:

  • ICOM (recommended): 'USB I/Q Package for HDSDR' downloaded from ICOM's website [link], or

  • SDR Console: A signed driver supplied with the SDR Console kit, this can only be installed on Windows 8 or higher (not Windows 7).

ICOM (Recommended)

To install the ICOM software follow the instructions with that package.

SDR Console

A signed driver is supplied with the SDR Console kit, you must install the driver for your R8600 as follows:

  • From the Control Panel select Device Manager
  • Right-click on IC-R8600 in the Universal Serial Bus devices
  • Select Update driver from the context menu
  • Select Browse my computer for driver software  (location depends on the folder where SDR Console is installed)
  • 32-Bit: select ICOMR8600.inf from C:\Program Files\SDR-Radio.com (V3)\Drivers/Win8Win10/x86
  • 64-Bit: select ICOMR8600.inf from C:\Program Files\SDR-Radio.com (V3)\Drivers/Win8Win10/x64
  • Windows Security will prompt you to confirm the installation, the driver is signed by SDR-Radio.com Ltd

That's it!





Operating In I/Q Mode

For more information about the topics below read "I/Q OUTPUT REFERENCE GUIDE iR8600 COMMUNICATIONS RECEIVER" on the ICOM website [link].

Front Panel

While the IC-R8600 is in the I/Q mode, [REMOTE] LED lights and the IC-R8600 is in the “Remote controlled mode,” thus you cannot operate the IC-R8600.

To exit the I/Q mode, send the command that cancels the mode, or push the [LOCAL] key on the IC-R8600 front panel. Turning OFF the IC-R8600’s power also exits the I/Q mode.

DC Spur

The I/Q data contains a DC component that is produced in the signal processing. The DC component appears as a constant frequency component positioned at the center frequency (0 Hz). Although this is removed in SDR Console it is recommended that you do not tune stations to the centre of the display as the spur removal code will affect this signal as well.

Bit Depth

The software allows you to select the bit depth from the ribbon bar's Home pane (first start the R8600). At 5.12MHz the maximum bit depth is 16 bits, for all other bandwidths the maximum bit depth is 24 bits. A higher bit depth supports better blocking dynamic range but requires a higher USB throughput.

Sample Frequency Max Bits Usable Bandwidth
5.12 MHz 16 4.46 MHz
3.84 MHz 24 3.31 MHz
1.92 MHz 24 1.63 MHz
960 kHz 24 815 kHz
480 kHz 24 408 kHz
240 kHz 24 203 kHz
