This is an App that decodes Morse code input from the microphone of iPad. 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. * The Pro version also supports waterfall display. [Control parameters] 1.Language select English and Japanese(KANA) 2.Audio Input Level 3.BPF ON/OFF 4.BPF of Center Frequency 5.BPF of Band Width 6.BPF of Shape 7. Notch ON/OFF 8. Notch Frequency 9.CW Speed Control ON/OFF 10.CW Speed Control Low, Mid1, Mid2 or High 11.Delete All Decoded Text 12Realtime CW Signal Display 13.Input signal recording function. 14.Playback function from the file list. 15.Support the Garbage Data reduction function [Note] Since the signal after BPF is output to the audio output, it can also be used as an AF-CW filter.
