One search, full depth
Search frequency, station, language, country, or code across the complete on-device directory.
Thousands of broadcasts.
One intelligent atlas.
Built on respected shortwave datasets and expanded with World Airband and World FM reference directories, arranged to surface the most locally relevant frequency information first.
Always within reach
Download the database once and keep exploring schedules wherever listening takes you.
Distance in context
When location data is available, see an approximate distance between you and the transmitter.
Nearby airports first
World Airband uses your location to list nearby airports first, helping you reach local tower, approach, ground, and information frequencies faster.
Your country’s FM stations first
World FM prioritizes frequency references for your current country, with station and city information where available.
Language codes,
written in full.
Shortwave databases use compact language codes. SWAtlas turns a code such as JPN into Japanese, so you can understand the broadcast language immediately while the original code remains available for searching and filtering.
- JPN becomes JapaneseThe database language code is displayed as the full, readable language name.
- The original code still worksSearch for JPN directly or select it in the ITU code filter.
- Country fields are decoded separatelyCompact country codes are also expanded into clear country names.
JPN
Never miss the moment.
Broadcast schedules should feel immediate, wherever you are. SWAtlas translates UTC, shows live progress, and brings you back at exactly the right time.
Broadcast alert
A quiet reminder,
right on cue.
Set an alert from any broadcast detail and return when the station comes on air.

From raw tones
to readable signals.
Open the Rig screen to check NOAA Space Weather, receive Radiofax images, decode Morse and RTTY, transcribe and translate spoken broadcasts on device, or record and enhance radio audio while keeping the original.
Radiofax
Weather charts, received as images.
Radiofax helps turn HF fax audio into readable image output, making it easier to capture weather maps, marine charts, and visual shortwave broadcasts directly from your radio setup. Smart sync automatically detects the incoming LPM and keeps the image aligned as it is received.
- Automatically detects LPM and syncs the fax signal
- Decode fax tones into image output
- Available from the main screen Rig button
Morse code
Dots and dashes, translated clearly.
The Morse decoder listens for CW tone patterns and translates them into readable text, helping operators follow call signs, numbers, symbols, and familiar shortwave exchanges with less friction. It automatically recognizes WPM, learns the rhythm of the signal, and applies the speed as it decodes.
- Automatically learns WPM and adapts while decoding
- Decode Morse audio into readable text
- Available from the main screen Rig button
RTTY
Two tones, turned into live text.
The RTTY decoder listens for the alternating mark and space tones used by radio teletype signals and converts them into readable characters as they arrive. Smart tuning helps identify the two tones and their shift, while live baud rate, polarity, and confidence readouts make it easier to understand the signal before decoding.
- Smart tuning tracks mark, space, and frequency shift
- Decode RTTY audio into readable live text
- Monitor baud rate, polarity, and decode confidence
Whisper transcription
Foreign broadcasts, understood in your language.
While the other Signal Tools decode specialist radio modes, Whisper helps you explore spoken shortwave broadcasts. Download the transcription and translation models once, turn speech into text, translate it into a language you choose, and archive both versions—all offline.
- Transcribe international voice broadcasts with an on-device Whisper model
- Translate transcripts into your selected target language
- Archive original and translated text for offline reading
Smart Radio Recorder
Keep the voice. Reduce the radio noise.
Record radio audio, reduce steady noise, and keep both the enhanced and original recordings. Finished recordings can be sent to Whisper Transcriber for on-device transcription and translation.
- Archive both enhanced and original recordings
- Trim, rename, play, and review saved sessions
- Continue from a recording to Whisper Transcriber
Space Weather
See radio conditions at a glance.
Review NOAA radio conditions, R-scale blackout status, geomagnetic forecasts, solar flux, X-ray activity, and the latest D-RAP map. The most recently downloaded report remains available offline.
- Monitor radio blackout and geomagnetic conditions
- Review the latest NOAA D-RAP world map
- Save reports for later comparison
