CW4ISR

CW4ISR is a Morse decoder that reads every station in the audio band at once. Decoding is done by rumo. The Go version is kept in the branch v1.

Get Started

Download the nightly build here.

Windows

Start cw4i.exe.

macOS

Install cw4i.app from cw4i.dmg.

Library

The crate is also a library, so that a host such as zlog-rs shows the same decoder in its own window.

Loading

Item	Role
Cw4i	Draws the controls, the waterfall and the lanes, and hands out picked words.
Pick	A picked callsign or number.
Stations	Stations built from the events of rumo.
decode	Decodes a whole recording.

A host depends on the crate without the application feature.

cw4i = { git = "https://github.com/nextzlog/cw4i", default-features = false }

Build

$ cargo build --release
$ ./target/release/cw4i

On macOS, wrap the build into dist/cw4i.app with the script below, so that it starts without a terminal window.

$ scripts/macos-app.sh
$ open dist/cw4i.app

Given WAV files, the application prints the stations heard without opening a window.

$ ./target/release/cw4i recording.wav

Test

$ cargo test
