What is indicated by the code "10-5"?

The code "10-5" is used in communication to signify "Relay message." This means that the sender is instructing the receiver to pass along or deliver the message to another party.

In the context of radio communication, especially among operators, clarity and brevity are essential. Using established codes like "10-5" helps to ensure that messages are conveyed quickly and efficiently without misinterpretation. This code is part of the "ten-codes," which are widely recognized among many radio communication users, including those in emergency services and broadcasting.

Phrases such as "message received and understood," typically align with codes like "10-4," while "returning to station" does not correlate with "10-5" but indicates a different communication purpose. Similarly, "location requested" pertains to another specific request, distinct from the action of relaying a message. Therefore, understanding "10-5" as "Relay message" allows operators to execute communication protocols correctly in various operational scenarios.
