IC9100 Firmware Update E3 2015

Icom has Released a new firmware update for the IC9100 radio.  IC-9100 Firmware Rev. E3 is now downloadable form the Icom Japan website. It is a stand alone .exe file that will install the E3 firmware update.

The new firmware corrects one item on the radio

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

Additionally, a USB3 compatible driver and cloning software update CS-9100 Rev. 1.01 is downloadable from the Icom website. (update in 2014)

its suggested you make sure you backup memories and settings for your radio, this upgrade suggests it wipes the radio memories (however my device retained all memories)


 How to check the firmware version on the Icom IC-9100 and IC-7410

  1. Turn off the transceiver
  2. Press and hold F4 and F5 while turning on the IC-9100. *DO NOT RELEASE F4 AND F5 UNTIL YOU HAVE READ THE VESION RESULTS.
  3. Results will appear at the bottom of the display

The latest IC-9100 versions should read (after E3 update)

  1. F_# = Front (currently no updates) 3.01-000
  2. M_# = Main (currently no updates) 3.42-E00
  3. DM_# = DSP Main (Current version should read 3.06 (00) )
  4. DS_# = DSP Sub (Current version should read3.08 (00) )

  1. My firmware matches everything except DM.
    I have 3.05 instead of the 3.06.

    Is that minor or should I do the entire Firmware update?


  2. 2 days with ICOM: bad data port in radio. I called Steve, National Sales Manager for BRO to see if there might be any leverage on warranty.

    Steve spent hour one taking notes.
    Good to his word he called me back later. We shared my PC. FOUR hours later he spotted a problem with wring files in wrong directory.

    Problem solved. While on the phone he also checked my radio to make sure the ALC overshoot was not a problem.

    People think I’m a bit zealous supporting HRO? When I got my ticket many years ago I was ready to spend 5 times what I did at the Charlotte Hamfest. Mark talked me down to one dual band to try at my shack and in the car. “Spend your money on your antenna”

    I called ICOM so they have the software solution on file.
