Real-time shortwave radio translator — Listen to ham radio stations worldwide and get live translations, right in your browser (desktop or smartphone).

Wavelingo connects to KiwiSDR receivers around the world, streams their audio in real time, transcribes spoken content, and translates it into your chosen language — all from a single web interface (dektop, tablet or smartphone).

• 🗺️ Interactive World Map — Browse and select KiwiSDR receivers worldwide (new added regularly)
• 📻 Live Radio Streaming — Connect to any KiwiSDR (if it is available) and listen to shortwave frequencies (0–30 MHz) with LSB/USB modulation
• 🎙️ Real-time Transcription — Automatic speech-to-text
• 🌍 Live Translation — Transcribed text is translated on-the-fly into 9 languages
• 📱 Responsive Design — Tabbed mobile layout and split-panel desktop layout

1. Select a receiver — Click a marker on the map to pick a KiwiSDR station
2. Set the frequency — Enter a frequency in kHz. Modulation is auto-selected (LSB below 10 MHz, USB above)
3. Connect — Click Connect to start streaming audio from the receiver
4. Translate — Click Translate to begin real-time transcription and translation
5. Choose your language — Use the language selector to pick your target translation language

• If a server is busy or down, try another one — status messages will guide you
• The audio level meter shows signal activity in real time
• Translations appear as subtitle-style text below the original transcription. You can change the target language at any time and all translations will be updated.
• Bold green text in translations highlights named entities (call signs, location, ...)

• Transcription sessions are limited in time
• Join the Telegram group for updates and support
