    FreeTRX v0.5.0 Pre-release

    DK1DA released this 2026-07-10 11:54:15 +00:00 | 35 commits to main since this release

    0.5.0

    • Fix: un-muting during an active QSO left the LED off instead of returning
      to green. On un-mute the green RX LED is now restored from the current receive
      state (active DMR slot or FM/digital signal), so an in-progress call lights green
      again.
    • MANUAL.md — a user-facing feature & usage guide covering both inherited
      OpenGD77 features and FreeTRX additions, each tagged 🟢 [FreeTRX] or ⚪
      [OpenGD77]. Includes the spectrum scope (VFO sweep, hold #), channel add/delete,
      mute, dimming, and a button reference.
    • Documentation website (website/) — MkDocs Material config that renders the
      markdown into a static, searchable HTML site (client-side search, dark/light
      theme). Built in Docker via ./website/build-docs.sh; the public URL is set with
      SITE_URL=…. For self-hosting on Forgejo.

    FreeTRX v0.4.0 Pre-release

    DK1DA released this 2026-07-10 10:49:45 +00:00 | 39 commits to main since this release

    0.4.0

    • On-radio channel add/delete. The Channel quick menu (top button) has two new
      entries:
      • new channel — creates a blank 145.500 MHz FM channel in the first free
        slot, adds it to the current zone, and opens Channel Details to edit it. The
        zone is reloaded so the channel is immediately navigable.
      • Delete Channel — deletes the selected channel after a confirmation, and
        scrubs it out of every zone that referenced it. Refuses to delete the last
        remaining channel, and respects the read-only/APRS channel lock.
      • The new menu strings are translated (German, French, Italian, Spanish,
        Portuguese, Dutch, Danish, Swedish, Catalan, Finnish, Czech; English fallback
        for the rest).
    • flash.sh now always rebuilds the language (.gla) packs, so edits to the
      language files are picked up instead of a stale pack being re-flashed.
    • Release script now flags every release before v1.0.0 as a pre-release
      (and corrects the flag on re-runs).

    FreeTRX v0.3.0 Pre-release

    DK1DA released this 2026-07-07 14:29:21 +00:00 | 44 commits to main since this release

    0.3.0

    • Fix a second voice-prompt crash on the Screen Dim menu row: the item label
      ("Screen Dim") is a raw literal, and the shared menu code voices labels via
      voicePromptsAppendLanguageString(), which crashes on any pointer outside the
      language table. That function now ignores non-language pointers, so a stray
      literal is skipped instead of hard-faulting. (The dim value is still announced.)

    FreeTRX v0.2.0 Pre-release

    DK1DA released this 2026-07-07 13:41:59 +00:00 | 45 commits to main since this release

    0.2.0

    • Fix crash opening Display Options with voice announcements on: the Screen
      Dim value ("100%"/"50%"/…) is a plain literal, but the shared menu code fed it to
      voicePromptsAppendLanguageString(), which derives the prompt index from the
      string's offset within the language table — a foreign pointer produced a garbage
      index and crashed. The value now goes through voicePromptsAppendString(). Also
      moved the dim-level high bit off a low legacy option bit (bit 2 → 29) and clamped
      the level so it can never index past the option arrays.
    • 7-segment frequency font: inactive segments are now off (background) instead
      of faintly lit — no dim "ghosting". "MHz" now matches the frequency colour, and
      there's 1px more space between the RX and TX frequency lines.
    • Screen dimming: added a 15% idle-dim level (Off / 100 / 50 / 30 / 15).
    • DM-1701 build support — the Docker build is now parameterized by platform;
      ./build-firmware.sh DM1701 produces OpenDM1701.bin (Baofeng DM-1701 /
      Retevis RT-84). Not officially tested yet.
    • Release script (scripts/forgejo-release.sh) now builds and attaches a
      single platform or all of them, and reuses an existing release.
    • README: added "What's different from OpenGD77" and a dedicated "Flashing"
      section.

    FreeTRX v0.1.0 Pre-release

    DK1DA released this 2026-07-06 16:34:10 +00:00 | 53 commits to main since this release

    0.1.0

    First versioned release of FreeTRX (fork of OpenGD77 R20260131).

    Features

    • Screen dimming — optional idle dimming of the backlight to a fraction of
      the configured brightness (Off / 100% / 50% / 30%), in Auto backlight mode.
      Any activity (keys, rotary, RX, TX) restores full brightness. New setting in
      Display Options.
    • Mute — one-tap audio mute:
      • SK2 short-tap toggles mute on the VFO/Channel screens (except while a DMR
        QSO is on screen, where SK2 keeps its "set TX TG to incoming" function).
      • Turning the volume knob fully down is also treated as muted.
      • While muted: a bold "M" appears in the status bar (left of the battery)
        and the red LED flashes (0.5 s every 2 s).

    Display / UI

    • S-meter redrawn as discrete blocks — 9 green blocks (S1–S9) plus 6 red
      blocks (S9+10…+60), with gaps and a proportionally-filled leading block, and a
      scale label row beneath (S1 S3 S5 S7 S9 / +20 +40 +60).
    • 7-segment "LED" frequency font for the VFO and SK1-held frequency display,
      with faintly-lit inactive segments; digits are wider than the normal font.
    • Main-menu icons — a small glyph next to each top-level menu entry.
    • Layout spacing adjusted so the contact/TG line, the DMR talkgroup/talker and
      the private-call caller ID clear the new S-meter label row.

    Fixes

    • DMR no longer hard-faults. The AMBE codec is now called through C function
      pointers instead of the old inline assembler (which modern GCC miscompiled),
      fixing the freeze-on-DMR that required a battery pull.
    • Fixed the DMR talkgroup/talker and private-call caller ID overlapping the
      S-meter labels.

    Build / Tooling

    • Dockerized build using the Arm GNU Toolchain 14 (matching the official
      builds); always a clean build. ./flash.sh helper for flashing with model,
      language and DMR donor.
    • Integrated the OpenGD77 screen grabber (gd-77_screen_grabber.py) and the
      GD-77 loader into the repo.
    • TOOLS.md documents building, flashing, screenshots and language files.

    Project

    • Renamed the project to FreeTRX (fork of OpenGD77). New README.md
      documenting the fork and its upstream source; original OpenGD77 README kept as
      README.OpenGD77.md. Added LICENSE.md reproducing the inherited OpenGD77
      license (modified BSD 3-Clause + non-commercial clause; not GPL-compatible).
    • On-screen branding renamed to FreeTRX (splash screen + Firmware Info name).
    • README notes this iteration is developed/tested only on the TYT MD-UV380 and
      Retevis RT-3S      , with a contact for testing on other supported radios.
    • Firmware-info credits simplified to "Marcus DK1DA" and a reference to
      "The original OpenGD77 authors".

    Misc

    • Added Marcus DK1DA to the firmware-info credits ("Modified Fork by").
