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
Antenna Switching – Share Between Multiple Radios
Recently, a friend asked how I do antenna switching at my shack. Here’s how. Read more
Ten Cent ADS-B Antenna Extends Range
My ten cent ADS-B antenna replaces the RTL-SDR stock antenna. Amazingly, it doubles my coverage of aircraft flying around Calgary.
Digital Audio Broadcasting – Norway First, Apparantly
This month, Norway will shut down its FM transmitters and replace them with Digital Audio Broadcasting. It becomes the first country to completely replace traditional analog FM with the new digital format. Read more
