Decepcionante

Es la aplicación más decepcionante e inservible que he probado jamás. Lo peor es que es de pago y debería ser mínimamente aceptable pero es pura basura. No la recomiendo en absoluto. No se os ocurra comprarla. Escribe lo que quiere hace lo que quiere escucha lo que le da la gana.

4 years old and great!

I think you have developed one of the best CW readers I’ve seen.
It’s a great aid to learning morse code 👍 73 de VK7WW

Don’t Waste Your Money

It’s easy to see why they do not offer a free trial on the software. It just freaking does not work.

Looks great but doesn’t work

I bought this app five years ago. I occasionally start it up to see if it finally works. It still thinks everything decodes a an “e.” If you are going to charge a premium fee for an app, it should provide the promised service. This app fails to do so and I cannot recommend it to anyone.

It works

A CW decoder that is simple an works! Great job

What are the key features of the Morse Code Decoder?

Key features include automatic and manual decoding modes, adjustable audio filter frequency, configurable WPM (words per minute) speed detection, background noise threshold settings, a built-in spectrogram for analyzing tones, and an optional DSP audio filter.

Is the Morse Code Decoder app free to use?

Yes, the application is available for free. There are no in-app purchases or advertisements mentioned in the provided description.

What devices is the Morse Code Decoder compatible with?

The app is designed for use on iPhones and iPads. It utilizes the device's microphone or headset input for audio signal processing.

How can I improve decoding accuracy with the Morse Code Decoder?

To improve accuracy, aim your device's microphone directly at the Morse code sound source to avoid noise cancellation. If automatic decoding struggles, utilize the manual settings to adjust the audio filter frequency, WPM speed, and background noise threshold. Refer to the help file on the developer's website for troubleshooting tips.
