Morse Words vs RST Decoder

HotPaw Morse Words is a aid to learning Morse Code. Audio learning can be a great brain exercise. This app can help you learn the sound of entire words in Morse Code. The app is a test generator which randomly picks from 250 very common English words and sends them in International Morse Code audio through your iPhone speaker or headset. The WPM (words per minute) speed can be easily set up to 100 WPM. You can also separately set the dot speed (for Farnsworth method code), and customize the tone frequency. Hit "Start" to start sending random Morse code text. You can choose "Show", to see the words displayed as they are sent to the speaker. This is helpful when first learning. After you are familiar with the sound of the words, you can "Hide" the display of the words sent, and attempt to copy them down on paper as your hear them. Then you can later show them in order to check how many words you copied correctly. Optionally you can paste a custom word list, from 5 to 500 words in length, using the Settings view.

This is an App that decodes Morse code input from the microphone. It is a Morse practice App that you can use to check if you are keying the correct code. Signals with good S/N can be decoded correctly, but signals with bad S/N cannot be decoded correctly. Also, the performance will be degraded for extremely slow or fast signals. Usually about 5 to 10 characters are required for speed synchronization of Morse Code. Adjust the input signal so that the peak value changes from level 6 to level 7. Make fine adjustments to each parameter according to the reception status. [Additional Functions] -In addition to the decoder using BPF, a new decoder using FFT has been added so that it can be switched according to the usage. -AFD (Auto Frequency Detector) function has been added to the decoder using BPF, and BPF can be set automatically by pressing the AFD button. -The decoder using FFT automatically follows the strongest signal in the band by AFD (Auto Frequency Detector) and AGC (Auto Gain Control). You can also hold the AFD / AGC parameters by pressing the Lock button. * There will be a time lag of about 1 to 2 seconds for AFD tracking. [Control parameters] 1. Audio Input Level 2.BPF ON/OFF 3.BPF of Center Frequency 4.BPF of Band Width 5.CW Speed Control ON/OFF 6.CW Speed Control Low, Mid1, Mid2 or High 7.Delete All Decoded Text 8.Realtime CW Signal Display 9.Input signal recording / playback function *Japanese/KANA text is not supported. [Note] Since the signal after BPF is output to the audio output, it can also be used as an AF-CW filter. [URL of this App working example video] https://youtu.be/Pwp7W4m-m34
