Morse code Decoder
The best decoder for morse code, in fact, is still the human brain. EhoCW is not the ultimate decoder, it is an attempt to help those who starts, but it is only effective when the manipulation is relatively steady.
Make sure that the AF signal is not to strong for the input of your sound card.
When the receiver is turned on and the analyzer is not lit, then the receiver decodes what is keyed with the key plugged into the joystick ou serial com port.
If both are lit, then the decoder receives pulses from the sound card via a digital filter BF, and displays the decoded characters on the screen.
The un-decoded characters are displayed in the form ‘dash and dots’ (...-.-- for example).
