User Reviews for RST Decoder

Works well!

After a few minutes to see what it’s all about, it showed the noise and code clearly. A bit of fiddling and I was copying nice code, as well as some pricy software.Of course, signal fading and bursts of occasional QRM would lose the code as most others also do.I will work more with this one, and so far I am very satisfied!

Doesn’t work at all

Won’t load

Works great

Works great for practicing and making sure I’m keying right, one thing I would like to see in this app is the ability to have the app in landscape.

Idiot hams don’t know how to use it.

If you think that this will copy someone with a bad fist, you’re an idiot. It does well with a strong signal and a good fist, as it should. The two decoding algorithms, Work well, even with QRN. If you don’t like what it does, then decode by ear, but go get a hearing aid, because you can’t hear like you did when you were in your 20s.

Pretty bad

Has potential but it has too much difficulty unless your going extremely slow, at 15 wpm it’s mistaking x for k and y which sound nothing like eachother and t gets mistaken for e and the other way around. Just not viable for anything serious, humans can do it as good or better than this 100% of the time. Maybe if there was a custom wpm option to put in your actual key speed it might have an easier time but I need to pause for about a second between each letter for it to process them. Most people don’t send much slower than 15 wpm so this isn’t the solution to your problems.

Description

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
