Dahdio CW morse decoder

Connect your radio's audio output to your iPhone or iPad and read the Morse code as it is sent. Use a USB audio interface or sound-card adapter, a radio with its own USB audio, or a cable into a headset input. Dahdio finds every CW signal in the audio and decodes them all at the same time. The station you are copying never changes on its own because a louder one turned up. EASY OR EXPERT TUNING, BEST OR ALL TEXT • Easy tuning: Dahdio finds the stations for you and shows them as marks on a tuning strip. Tap one to copy it. • Expert tuning: a waterfall with a marker on every channel. Tap a marker to copy that station, or tap the waterfall to pin a channel on that frequency; long-press a pin to let it go. Automatic channel finding can be turned off, so you choose every channel yourself. • Best text: the station you are copying, full screen. • All text: every station's copy at once, one row each with its frequency and speed, the station you are copying first. Tap a row to copy that station. BUILT FOR REAL BAND CONDITIONS, OVER A DIRECT AUDIO CONNECTION • Three decoders vote on every word: a signal-processing decoder, a neural network and a search decoder. Where they disagree, the vote decides. • Developed and tested on real off-air recordings, hand-checked against what was actually sent: fading, noise, interference, and hand-sent Morse with all its quirks, not just clean machine-generated code. • Follows each station's own speed and pitch automatically. • Stays quiet on noise and carriers instead of filling the screen with junk. Want to see everything anyway? One switch shows it. • A language model helps with common amateur-radio words and abbreviations. You choose how much it may help. • Prosigns shown as prosigns: AR, BT, KN, SK. • Text that may still change is shown dimmed until the decoder is sure. SEND AS WELL AS RECEIVE • A keyboard made for Morse: letters, numbers, prosigns and punctuation. • Send each letter as you type, each word when you press space, or compose a whole reply first. • Anything not yet sent can still be edited. A Correct key sends the usual spaced e's and the word again. • Works with a hardware keyboard too: Return sends, and F1–F12 send your stored messages. • Adjustable speed, sidetone pitch and volume. • Receive, send, or both on one screen: drag the divider or tap RX, RX+TX or TX. LOG AS YOU OPERATE • A logger for contests, POTA and SOTA activations and everyday QSOs, on the same screen as the decoder. • The callsign and exchange are filled in from what the decoder heard. Nothing is logged until you confirm it. • Dupe and worked-before checks. Export ADIF (with per-park POTA files) and Cabrillo. NO CABLE TO HAND? • The built-in microphone works for a quick try, but copy is much weaker than with a cable or USB interface. PRIVATE BY DESIGN • Decoding happens entirely on your device. No account, no sign-in, and no internet connection needed to decode. • Audio is decoded as it arrives and is never recorded or sent anywhere. • Your log stays on your device until you export it. Early access: everything is unlocked until 31 December 2026. After that, the free version decodes up to 4 stations at once, for 10 minutes per session and 30 minutes a day.
