What are main topics covered in the General Class exam?

Operating Fundamentals

The General Class exam covers operating practices, including modes of transmission, call signs, and operating procedures. Understanding how to properly use call signs, signal reports, and net control operations is crucial. For example, when operating on 20 meters, you must follow the band plan, which specifies the frequency ranges for different modes. You must also be able to describe the difference between a CW (continuous wave) signal and an SSB (single sideband) signal.

Electronics and Theory

Electronics and theory are also key components of the General Class exam. You’ll be tested on your understanding of AC and DC circuits, including series and parallel circuits, and how to calculate voltage, current, and resistance. You’ll also need to know how to analyze and troubleshoot simple circuits. For example, you should be able to determine the type of circuit and identify the components based on a circuit diagram. Additionally, you’ll be tested on your knowledge of amplifier circuits, including common types of amplifiers and their uses.

Radio Wave Propagation and Antenna Systems

The General Class exam also covers radio wave propagation and antenna systems. You’ll need to understand how to analyze and predict radio wave propagation, including the effects of ionospheric and tropospheric propagation. You’ll also need to know how to design and install basic antenna systems, including dipoles, monopoles, and Yagi antennas. For example, you should be able to calculate the length of a dipole antenna based on the frequency and desired band, and explain the benefits of using a directional antenna in certain scenarios.
