Modern amateur radio transceivers are increasingly software-defined devices, which means firmware updates can have a significant impact on how a radio performs. A new firmware release may fix operating problems, improve receiver or transmitter behavior, add digital-mode functions, introduce new CAT commands, improve APRS or D-STAR operation, expand storage support, change network features or even add completely new capabilities to an existing transceiver.
This continuously updated Ham Radio Firmware Database tracks the latest publicly available firmware for current amateur radio transceivers from Yaesu, Icom, Kenwood, Xiegu, FlexRadio, Elecraft, Lab599, QRP Labs, Apache Labs, Expert Electronics and AnyTone.
For radios that contain several independently updated components — such as MAIN, DISPLAY, DSP, SDR, SUB, FPGA, MCU or baseband firmware — the relevant versions are listed separately. Software-defined platforms such as FlexRadio, ANAN and SunSDR are treated slightly differently because their internal radio firmware is closely connected with software such as SmartSDR, piHPSDR, p2app and ExpertSDR3.
Last database check:
The database primarily tracks stable or production firmware releases. Beta firmware may also be mentioned when it introduces an important new function or fixes a significant problem, but beta versions are clearly identified and are not treated as the recommended production firmware.
Firmware availability can vary by radio region, hardware revision and destination version. Always confirm the exact model and regional version of your transceiver before performing an update. Back up memories, settings and codeplugs whenever possible, read the manufacturer's update instructions carefully and never interrupt power while firmware is being written.
Firmware files should always be downloaded from the radio manufacturer's official support or download service, or from an authorized regional distributor when the manufacturer uses regional firmware distribution.
Yaesu
Yaesu uses several different firmware architectures across its current amateur radio range. Modern SDR transceivers such as the FTX-1, FT-710 and FTDX series contain several firmware components, while simpler radios may have only a MAIN firmware image. Regional firmware versions can also differ, so the destination version of the radio must always be checked before updating.
