Recording Radio Signals with SDR
Recording radio signals is easy with modern software defined radios. Read more
Morse Decoder First Run Successful
My Morse Decoder first run was successful. Building the prototype quickly gets you on the learning curve faster. Read more
Arduino Analog Sampling – It’s All About Timing
Arduino analog sampling is a lot different than on an ordinary PC. Read more
Signal Analysis for a Morse Decoder
Audio signals exist in the time domain. Sound is a complex mixture of waves at different frequencies. These waves vary in shape and strength. Traditionally, engineers consider audio as a whole bunch of sinusoidal tones mixed together. You can visualize this complex waveform on an oscilloscope. Read more
Arduino Morse Decoder – How It Works
Let’s examine how an Arduino Morse Decoder works, and look at some popular solutions available. Read more
Encourage Morse Code with Arduino Display
I have been looking for a way to encourage Morse Code use in my ham radio operating. The answer will be a little Arduino project that decodes Morse alongside the radio. Read more
