About

RST Decoder Pro

This application decodes Morse code from your device's microphone, offering two decoding methods (BPF and FFT) with adjustable parameters. It includes features like automatic frequency detection, gain control, and real-time signal display for accurate Morse code practice and reception.

Highlights
  • Microphone Morse code decoding
  • BPF and FFT decoding methods
  • Auto Frequency Detector (AFD)
  • Auto Gain Control (AGC)
  • Real-time CW signal display
  • Waterfall display (Pro version)
  • Adjustable control parameters
Read full description

This is an App that decodes Morse code input from the microphone. I recommend that you try the basic functions and usage with the free version before purchasing. 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.
