Mode was a full-width select: 483px of the row to display "FM". The modes are three or four characters and there are at most twelve, so they become a segmented group like the Unit and Step Scale pickers beside them — a third of the width, and one click instead of two. The <select> stays as the mode's value. A dozen call sites and several plugins read #mode.value, so replacing it outright would have reached much further than a layout change should; it is hidden from sight and from assistive tech, the buttons write to it, and everything downstream runs unchanged. Every writer re-syncs the buttons, the plugins through a new trxCore.syncModePicker. The row itself was a grid with a track per column, but the WFM, SAM and transmit columns are hidden on most rigs, so it ended in some 500px of hole. It packs left now. Same fault one level down: the power buttons sat in three fixed tracks, so a rig with neither transmit nor lock kept two empty ones and left its label chip stranded at the far edge. Unit and Step Scale move out of the frequency row and in beside the wheel and the +/- they modify, which were some 600px away. Signed-off-by: Stan Grams <sjg@haxx.space>
trx-rs splits radio hardware access from user-facing interfaces so you can run
rig control, SDR DSP, decoding, audio streaming, and web access as separate,
composable pieces.
| Backends | Yaesu FT-817, Yaesu FT-450D, SoapySDR |
| Frontends | Web UI, rigctl-compatible TCP, JSON-over-TCP |
| Decoders | AIS, APRS, CW, FT8, RDS, VDES, WSPR |
| Audio | Opus streaming between server, client, and browser |
Quick Start
1. Install dependencies
Debian / Ubuntu
sudo apt install build-essential pkg-config cmake libopus-dev libasound2-dev
# Optional — SDR support
sudo apt install libsoapysdr-dev
Fedora
sudo dnf install gcc pkg-config cmake opus-devel alsa-lib-devel
# Optional — SDR support
sudo dnf install SoapySDR-devel
Arch Linux
sudo pacman -S base-devel pkgconf cmake opus alsa-lib
# Optional — SDR support
sudo pacman -S soapysdr
macOS (Homebrew)
brew install cmake opus
# Optional — SDR support
brew install soapysdr
See Build Requirements in the wiki for details on each library.
Note:
cmakeis required even when a system Opus library is installed. Theaudiopus_syscrate probes for Opus viapkg-config; if it is not found (orpkg-configis unavailable), it falls back to compiling a vendored copy of Opus with CMake. A missingcmaketherefore fails the build withis cmake not installed?rather than a missing-Opus error.
2. Build
cargo build --release
Build without SDR support: cargo build --release --no-default-features
3. Configure
Run the interactive setup wizard to generate config files for your station:
./target/release/trx-configurator
The wizard walks you through rig selection, serial port detection, audio
settings, and frontend options, then writes trx-server.toml and
trx-client.toml.
Alternatively, generate example configs and edit them by hand:
./target/release/trx-server --print-config > trx-server.toml
./target/release/trx-client --print-config > trx-client.toml
4. Run
./target/release/trx-server --config trx-server.toml
./target/release/trx-client --config trx-client.toml
Open the configured HTTP frontend address in a browser (default http://localhost:8080).

Each trx-server owns one or more rigs and runs DSP, decoding, and audio capture locally.
A trx-client connects to any number of servers over TCP and exposes them through
a unified set of frontends.
