The Physics of Morse Code: Efficiency in Simplicity


Introduction Morse code, a method of encoding text characters as standardized sequences of two different signal durations, called dots and dashes, has remained a resilient and efficient mode of communication. It’s particularly revered in the world of amateur radio, where it serves not just as a bridge to the past but as a testament to … Read more

Propagation of Radio Waves: Ground Wave vs. Skywave

Propagation of Radio Waves Ground Wave vs. Skywave

Radio wave propagation plays a pivotal role in the world of amateur radio, dictating how signals travel over distances and ultimately determine the reach and clarity of communications. This phenomenon, governed by the principles of physics and influenced by the Earth’s atmosphere and surface, is crucial for amateur radio operators to understand and utilize effectively. … Read more

James Clerk Maxwell and the Prediction of Radio Waves

James Clerk Maxwell Statue

James Clerk Maxwell, a Scottish physicist, made an indelible mark on the field of physics with his profound contributions, most notably his theory of electromagnetism. Born in 1831, Maxwell’s work bridged the gap between the mechanical and the electromagnetic, a leap that would fundamentally alter our understanding of the physical world. In 1865, through “A … Read more
