So, how do I get a Morse code signal into my decoding program? PortAudio reads Morse code audio just fine. Read more
My Morse Decoder Demonstration
Before we dig deeper into the nuts and bolts, I thought I should provide a Morse Decoder demonstration. Watch the video and read all about it! Read more
Morse Decoder Architecture
Today we will describe a single channel Morse decoder architecture. These are the systems and structures I will need to write a decoding program. Read more
Decoding Morse is All about Timing
Whether you do it with a pencil, in your head or with a computer program, decoding Morse is all about timing. Let’s get started. Read more
Head Copy – Subconscious Morse Decoding
What is consciousness? How does subconscious Morse decoding work? Understanding head copy needs a deep dive. Read more
Conscious Morse Decoding in Action
When you use your mind for conscious Morse decoding, you can do well at lower speeds. But you run out of brainpower as speeds increase. Read more
