Firmware Updates / Software Downloads


Model name IC-9100
Download Type Firmware
Version Release E3
Update 2015/01/27


The firmware update modifies the IC-9100's transmitted DTCS code modulation waveform so undesired sound is not heard at the receiver.

  • A USB cable is required. (A-B type, purchase separately)
    The firmware is updated through the USB port on the rear panel of the IC-9100.
  • You must install the USB driver before connecting the USB cable between the IC-9100 and the PC. Download the USB driver here.
  • Save the setting data using the optional CS-9100 cloning software before starting the firmware update.
  • Thoroughly read "Firmware update instructions (here)"to know what the update requires.
  • Never turn OFF the transceiver power or disconnect the USB cable during the update.
  • Never connect anything, not even a cable, to the REMOTE jack, otherwise the firmware update may fail.
  • If you connect two or more IC-9100s to the PC, turn the power ON for only the one that you want to update as the update tool works on only one transceiver at a time.
