RST Decoder vs QRS

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

QRS teaches Morse code the way it sticks: by sound, at honest speed, two characters at a time. - Learn: the Koch method. Characters play at real speed from the first lesson; you tap what you heard, and a new character joins when your accuracy holds. No charts to memorize, no counting dits. - Copy: head-copy practice with random groups and real ham-radio vocabulary, with the silences stretched while you're learning (Farnsworth spacing) and honest when you're ready. - Key: a straight key on the screen. Squeeze a dit, lean a dah — the app decodes your sending live, so you can watch your fist improve. - Chart: the whole code, every character playable, for the moments you just have to look. No account, no ads, nothing collected, works entirely offline. No license or radio needed — Morse is a skill you can start tonight. "QRS" is the Q code for "send more slowly." Only at first. Part of the Q-code family: QSX, QRX, QSO, QTH, QRG, QSY, QRV.
