Firmware Update Preparation

microSD Card Preparation

To perform a firmware update, you need a commercially available microSD card that has been formatted (initialized) with the FTX-1 series. Refer to the Operation Manual's section on "Using a microSD Card" for compatible cards and formatting methods.

Downloading Firmware and Copying to microSD Card

1. Download the compressed firmware file "FTX-1_JPN_Firmware_Update_xxxxxx.zip" from the YAESU website.
2. Extract the downloaded compressed file. For Windows, right-click the downloaded file and select "Extract All". The firmware files (with the .SFL extension) will be located in the "FTX-1_JPN_Firmware_Update_xxxxXXX" folder created during extraction. Firmware file names are as follows:
   • DISPLAY: FTX-1_DISPLAY_Vxxxx.SFL
   • MAIN: FTX-1_MAIN_Vxxxx.SFL
   • DSP: FTX-1_IFDSP_Vxxxx.SFL
   • SDR: FTX-1_SDR_Vxxxx.SFL
   • SPA-1: SPA-1_CTRL_Vxxxx.SFL
   (xxxx represents the version number.)
3. Copy the firmware files (SFL extension) directly to the root of the "FTX-1" folder on the microSD card. Copying files to any other folder will prevent them from being recognized and the update from occurring.
