MorseDecoder App Details

The HotPaw Morse Code Decoder translates Morse Code sound into text. Just use the microphone or headset input on your iPhone or iPad for the audio signal input, and watch decoded text appear. The Morse Code Decoder includes both an automatic decoding mode, plus manual controls to allow the decoding of weaker signals in noise and QRM. Manually adjustable parameters include the frequency of the audio filter, the WPM dot/dash speed used for detecting characters, the threshold level of background noise, and whether Farnsworth timing is to be used for detecting spaces between individual characters. The Morse Code Decoder includes a built-in spectrogram to help determine the audio frequency of the Morse Code tones. Use the optional narrow-band DSP audio filter to help filter out background noise. The audio filter works for tone frequencies from 300 to 2400 Hz. Please do not try to decode tones outside this range. The Morse code WPM (words per minute) detection speed is automatically adaptive from about 8 to 40 WPM, and can be locked to the current estimated WPM dot speed. You can also manually set the WPM code speed if the automatic speed detection guesses incorrectly. A QRQ High Speed WPM mode setting allows decoding much higher WPM speeds in the range of 30 to 80 WPM. Please aim your iPhone microphone at the Morse Code sound source so that the iPhone's noise cancelling microphone doesn't cancel it out. You can see if sound is getting to the iPhone by seeing a peak in the spectrum display. Please use the manual settings if automatic decoding does not adjust to the frequency, WPM. or background noise threshold level properly. Decoding will not work if the audio filter or WPM are set incorrectly, or there is a lot of background noise or room echoes above the threshold setting. Please see the help file on the HotPaw website for hints as to how to solve decoding issues.

    No matter what settings I use on my iPhone X it will not work. I even used a known recording that was clear with no background noise and still only pick up a couple letters rest was trash needs updated for new phones wasted my $10
  • Works great if you set it right.

    I have a Yaesu ft 857. I hav to change my receiver to 700hz or the iPhone WILL NOT hear the CW. I also find it useful to set the manual speed a little above the current words per minute. A person can spend his whole life developing a CW decoder and it will never work like what’s in between your ears. It really has a hard time decoding sloppy straight keys but extremely well with iambic decoding. It decodes straight key practice oscillator with precision sending. Most people use paddles or sticks anyway. This app is great for backup when I’m focused on a letter and now 14 letters behind and can jut glance over to catch up again. Apps absolutely worth the money. Maybe not the big app but this one is great. I’m extremely happy. Waaaay cheaper then a decoder on $15k radio that barely works and some commercial one that works poorly too. You shouldn’t regret it, (use manual settings) I don’t!

    I tried a lot of the free and cheap CW decoder apps, but nothing worked or worked reliably. I bit the bullet on this $10 purchase and I’m glad I did. I placed this next to a 60-meter radio with a poor signal, and this decoded the signal almost perfectly. 73, HotPaw! The in-app documentation is a wall of text, but it’s easy enough to figure out on the fly.

    I hated trying to import my Morse code to the computer. It took way to long. This made my life so much easier. Held it up to the tv and gave me what I needed to move on.

    Used the app to decode the Morse on battlefield one and it worked perfectly. So worth it!

    App is highly unreliable and basically does not work. Save your money. Very sad to have been allowed for sale in the App Store.

    Another unusable app regardless of the hype and excuse written instructions 2 hours of “ adjusting mic position, volume levels and nothing but cryptic decoding. Not usable and only attempts code to alpha and does it poorly
  • Everything is an E

    At least every other letter this app detects is an E. If there is background noise you have no chance, it will get no sound or it will get all the wrong sounds. I do not recommend getting this app.

    I have tried repeatedly to get this to decode cw. I see others have had success, but not me. Tried all settings it likes the letter E but thats it. Don't bother, learn cw the proper way and decode with the grey matter between your ears. 73
  • Cool little App!

    I didn't know what to do expect but I tried. I really expected a serious learning curve, but it worked right away. I made no changes at all -- just held my phone by my radio speaker and like magic the letters appeared. I did morse code in the Army 50 yrs ago and don't remember much more than CQ for asking a station to respond and the 5 or 6 alpha numerical of a call sign, but there they were-- over and over. I put it on my ipad3 and it works just as well. I clicked on the filter and it seemed to work a bit better than the phone. I'm very satisfied!! Glad I spent the cash!!
