Reloading a second time sometimes showed history the first load did not, and the safety valve is why: it called one function that both released the buffered live decodes and tore the history worker down, so any load where the replay had not finished inside twenty seconds — a large backlog, a cold cache, a slow link — dropped whatever had not arrived, without a word. A reload got another go at it, and the second one is faster because everything is cached by then. Those are two separate things now. At the timeout the live decodes are released so the panels are not held back, the replay carries on, and the progress says so. The fallback's error path retries once and then says "Decode history unavailable" rather than leaving the operator to guess whether there was anything to see. The progress is no longer a scrim. It was fixed to the whole viewport with a wash over the page — the waterfall, the decode panels, all of it — for the length of the replay, which is exactly when there is something worth watching. It is a corner card with a bar: indeterminate while the payload is on the wire, then filling as N of M messages replay. None of this was reachable from a test. /decode/history answers in CBOR and the worker reads the body as CBOR unconditionally, but the fixture served JSON, so every browser run had been exercising the client's retry path and never its history path. It encodes CBOR now, including the 64-bit form the millisecond timestamps need, and decode-flow serves 1200 records and holds the client to restoring all of them on the first load, showing progress while it does, and never covering the page with it.

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.
