Decline of the ARRL
Many radio amateurs feel the decline of the ARRL is here, they have grown increasingly frustrated with the current direction of the ARRL. Although the organization once stood as the…
RF Exposure: Understanding The Law
RF exposure refers to the interaction between radio frequency energy and the human body. This exposure occurs when you transmit or receive signals using any radio device, including amateur radios,…
5/8 Wave Antenna: Bigger Is Better?
A 5/8 wave antenna stands out as one of the most efficient radiator designs used in HF, VHF, and especially CB and 2-meter/440-MHz applications. It offers higher performance than a…
Understanding the Sporadic E Layer
Understanding the Sporadic E Layer, often called “Es,” is one of the most fascinating and unpredictable features of the ionosphere. It forms thin, dense patches of ionization in the E…
VOACAP for Propagation Forecasting
VOACAP for Propagation Forecasting, or Voice of America Coverage Analysis Program, is a powerful tool for predicting radio wave propagation. Amateur radio operators, emergency communication teams, and shortwave broadcasters use…
Satellite Tracking Basics
Satellite tracking is an exciting part of amateur radio and space communications. Many satellites pass over your location every day, and some carry amateur radio payloads or weather instruments. To…
Antenna Takeoff Angle: Which One Is Best
Antenna takeoff angle plays a vital role in determining how well your signal travels and where it is heard. In simple terms, the takeoff angle is the angle above the…
Seasonal Propagation Changes: What to Expect
Seasonal propagation changes because it depends on atmospheric conditions, solar activity, and time of year. As the seasons shift, these factors interact in unique ways, dramatically affecting how radio waves…
Geomagnetic Storms and Their Impact on HF
Geomagnetic storms are powerful space weather events that significantly influence HF radio communication. These storms occur when charged particles from the sun, known as solar wind, interact with Earth’s magnetic…
