SWAtlas - Shortwave Explorer

SWAtlas helps you find worldwide shortwave broadcasts, plan your listening and keep a record of what you hear. Search Aoki and EiBi schedules by frequency or station name, with FM and airband information also available. A separate radio receiver is required for listening. SWAtlas does not receive radio signals or stream broadcasts. Explore broadcasts - View station, country, language, schedule and operating days. - Filter by band, country, language, day and on-air status. Find broadcasts on air at a chosen time or overlapping a time range, using UTC or local time. - Search within a frequency tolerance and set start or end alerts for supported broadcasts. - Explore shortwave, FM and airband map layers and check distances to transmitter locations. Some map positions represent an approximate area. - Find suggested listening targets and manage failed reception records by station, receiver or environment. Suggestions do not guarantee reception. Keep your listening memories - Save reception logs with ratings, notes and receiver details, then browse them in the calendar and archive. - Create a QSL-style reception card with station and frequency details, transmitter information, a day/night graph and a summary of the latest saved NOAA data. - Cards use English, while your notes remain as entered. Choose UTC or local time and whether to show your reception location. - Enjoy the printing animation, haptics and zoom, then save the image to Photos or share it. - Read a card's QR code using the camera or a photo to check its digital signature and compare it with local records. This checks the encoded data, not whether a broadcast was actually received. On-device signal tools - Convert Weatherfax audio into images with Radiofax, with automatic correction and manual adjustment. - Decode Morse and RTTY audio into text. Morse follows changing sending speeds and supports WPM adjustment and re-decoding by segment while the original audio remains available. - Transcribe microphone audio or recordings with Whisper, then translate the text using a separately downloaded translation model. - Send completed Morse and RTTY text to the transcription page for translation when the translation model is installed. - Record radio audio or speech with Smart Radio Recorder, apply noise reduction and send recordings for transcription. - Check WEFAX schedules and NOAA space weather. Your data, ready when you need it - Back up and restore reception logs, failed reception records, settings and saved tool data. - Browse stored broadcast data offline. Database updates are checked and applied automatically. - Internet access is required for updates, model downloads, fresh NOAA data and some map features. Transcription and translation work offline after the required models are downloaded. - Supports light and dark modes. Recordings, logs and decoded text are stored on your device. Signal decoding, transcription and translation run on-device. Data is sent to your chosen destination when you export or share it. Feedback messages may include app and device information and limited diagnostics.
