Q Codes are a set of three-letter codes used in radio communication to convey specific information quickly and efficiently. Originally developed for maritime and aviation use, these codes help reduce misunderstandings and save time by providing standardized phrases. For example, the code QTH indicates the sender's location, while QRM refers to interference from other signals. These codes are particularly useful in emergency situations where clear communication is crucial. They are widely recognized in amateur radio and among professional operators, making it easier for individuals to communicate across different languages and regions. Overall, Q Codes enhance clarity and efficiency in radio transmissions.
