Reads Morse code (CW) from your radio and from recordings — a neural network trained on real contacts. The program is free. Receive only: it never transmits.

• Live from the radio’s sound card (also two receivers: L / R channel) or a WAV / MP3 file.
• Waterfall with a program filter — click a signal and the network listens to it only.
• Frequency and mode read from the radio (Hamlib, OmniRig), “Tune” on a click.
• Stations in a contact marked with letters and colours, readability of every word, one-click word correction.
• QSO fields, saving to ADIF and to logging programs.
• Windows, macOS (Apple Silicon) and Linux; 31 languages.

Test version (beta): the program works, but it may make mistakes and change. Feedback and bug reports are welcome.

Help the decoder

The decoder learns from real contacts. Correct the words you know for sure in the program and click “Help the decoder” — the piece with its audio goes to training the network, without your data. Privacy
