Early Use in Radio Communication

The early use of radio communication played a pivotal role in the development and widespread adoption of the phrase "10-4," a term that has become synonymous with confirmation and understanding. In the late 19th and early 20th centuries, radio technology began to emerge as a powerful tool for real-time communication over long distances.
