GopherTrunk v0.4.0

Install

Windows 11 (x64): download gophertrunk-v0.4.0-windows-amd64-setup.exe and double-click. The installer adds GopherTrunk to your Start Menu — single static binary, no DLLs to ship — and prompts for one data folder (default: Documents\GopherTrunk) that holds everything else: config, recordings, IQ captures, exports, the database, logs, and the browser-based consoles (standard, Signal Lab, Config Builder). After install, follow INSTALL-WINDOWS.md to install the WinUSB driver via Zadig — the OS won't see your RTL-SDR until you do this once.

Windows on ARM: extract gophertrunk-v0.4.0-windows-arm64.zip (no installer for arm64 yet — portable ZIP only). The web consoles live in the gophertrunk-web\ subfolder inside the zip (siglab\ and configbuilder\ alongside the standard console).

macOS: extract gophertrunk-v0.4.0-darwin-arm64.tar.gz (Apple Silicon) or gophertrunk-v0.4.0-darwin-amd64.tar.gz (Intel) and run ./gophertrunk. Builds are unsigned — right-click → Open the first time to bypass Gatekeeper.

Linux: extract gophertrunk-v0.4.0-linux-amd64.tar.gz (x86_64) or gophertrunk-v0.4.0-linux-arm64.tar.gz (aarch64, e.g. Raspberry Pi 4/5) and run ./gophertrunk. Single static binary; no system dependencies needed.

Web operator console: every archive includes a standalone gophertrunk-web/ folder with all three consoles — the standard console at the top, plus siglab/ and configbuilder/. Open the relevant index.html in any browser and point it at a running daemon. Setup walkthrough: gophertrunk.org/web.html.

All artifacts are SHA-256-checksummed in SHA256SUMS.
