All versions below were published by Icom on icomjapan.com, icomamerica.com, icomeurope.com and icom.co.jp. Third-party and modified firmware is never listed.

  1. Version 1.42 Latest Released May 15, 2024 First seen Sep 6, 2026

    Adds IC-PW2 compatibility for linked manual tuning and transmission control, improves Manual All Reset. — summary by updatemystuff.com

    Show release notes

    Changes from Version 1.41

    [Added linkage function with IC-PW2]

    • Supported for th​e Linked manual tuning with IC-PW2.
    • Supported for the IC-PW2 Transmission Interlock control.

    [Any other changes]

    • Improved the Manual All Reset operation.

    When the All Reset cannot be performed from the RESET screen, holding down the [CLEAR] and [V/M] keys and turning ON with the [POWER] key will manually​ perform an All Reset. The Manual All Reset operation is improved by connecting the external power supply instead of the [POWER] key.

    For details, please refer to "Information IC-7300 Version 1.42."

    Show release notes

    Changes from Version 1.40

    • Added the set item to detect the Microphone PTT operation during transmission o​ther than the Microphone PTT operation.
    • When in the Center mode of the Spectrum scope screen, the REF level setting does not reflect the scope waveform during transmission.
    • This firmware update version 1.41 has been improved, so it will not reset settings and memories.

    If the firmware is updated from version 1.40 or earlier, the settings and memories are not​ reset.

    However, if the firmware is reverted to 1.41 from a later version (after 1.41), the settings and memories may be reset.
