Update FrontendSpawner trait and related functions to accept and pass Arc<FrontendRuntimeContext> parameter instead of relying on global accessors for audio channels, decode channels, and auth tokens. Changes: - FrontendSpawner::spawn_frontend now accepts context parameter - FrontendSpawnFn type signature includes context parameter - FrontendRegistrationContext::spawn_frontend passes context to spawner - Global spawn_frontend function accepts and passes context This enables frontends to receive runtime data explicitly without accessing globals, improving testability and supporting multiple concurrent frontends with different contexts.

trx-rs (work in progress)
This is an early, untested snapshot of a transceiver control stack (core + backend + frontends). Things may change quickly and APIs are not stable yet. Expect rough edges and bugs; use at your own risk and please report issues you hit. Features, tests and docs are still being written (or not).
The rig task is now driven by the controller components (state machine, handlers, and policies). Polling and retry behavior are configurable via the [behavior] section in the config file.
Supported backends
- Yaesu FT-817 (feature-gated crate
trx-backend-ft817) - Planned: other rigs I own; contributions and reports are welcome.
Frontends
- HTTP status/control frontend (
trx-frontend-http) - JSON TCP control frontend (
trx-frontend-http-json) - rigctl-compatible TCP frontend (
trx-frontend-rigctl, listens on 127.0.0.1:4532)
Audio streaming
Bidirectional Opus audio streaming between server, client, and browser.
- Server captures audio from a configured input device (cpal), encodes to Opus, and streams over a dedicated TCP connection (default port 4533). TX audio received from clients is decoded and played back.
- Client connects to the server's audio TCP port and relays Opus frames to/from the HTTP frontend via a WebSocket at
/audio. - Browser connects to the
/audioWebSocket, decodes Opus via WebCodecsAudioDecoder, and plays RX audio. TX audio is captured viagetUserMediaand encoded with WebCodecsAudioEncoder.
Enable with [audio] enabled = true in the server config and [frontends.audio] enabled = true in the client config.
Dependencies
System libraries
The following system libraries are required at build time:
| Library | Purpose | Install |
|---|---|---|
| libopus | Opus audio codec encoding/decoding | zb install opus (or your system package manager) |
| cmake | Required by the audiopus_sys build script if libopus is not found via pkg-config |
zb install cmake |
| pkg-config / pkgconf | Locates system libopus during build | zb install pkgconf |
| Core Audio (macOS) / ALSA (Linux) | Audio device access via cpal | Provided by the OS (macOS) or alsa-lib-dev (Linux) |
Plugin discovery
trx-server and trx-client can load shared-library plugins that register backends/frontends
via a trx_register entrypoint. Search paths:
./plugins~/.config/trx-rs/pluginsTRX_PLUGIN_DIRS(path-separated)
Example plugin: examples/trx-plugin-example
