Amateur Radio Practices
Each group below is a real teaching page, not just a topic list. Read the explanation, use the checklist to make sure the main ideas are sticking, then quiz that group if you want an immediate check.
G4A
Station Configuration & Operation
A capable station is more than a transceiver. Audio settings, filters, antenna switching, accessories, and computer interfaces all affect whether the signal is clean and the receiver is easy to use.
Study G4A →G4BTests & Test Equipment
Test equipment becomes useful when you know what quantity it measures and how the instrument itself can affect the circuit being measured.
Study G4B →G4CRFI, Grounding & Bonding
Interference often comes from current flowing where you did not intend it to flow. Grounding, bonding, filtering, and common-mode control are different tools for different paths.
Study G4C →G4DSpeech Processing, S-Meters & Band Edges
Meters and processors are useful only when you know what they are telling you. This group connects front-panel indications with the actual signal on the air.
Study G4D →G4EMobile, Portable & Alternative Power
Portable and mobile operation makes power distribution part of radio operation. Voltage drop, battery chemistry, conductor size, and charging sources can determine whether the station works reliably.
Study G4E →Close the loop
