Question
What is meant by “check” in a radiogram header?
Answer Options
- A) The number of words or word equivalents in the text portion of the message
- B) The call sign of the originating station
- C) A list of stations that have relayed the message
- D) A box on the message form that indicates that the message was received and/or relayed
Correct Answer: A
Explanation
The “Check” is a crucial part of the Preamble (T2C10) in a formal radiogram message. It is a simple number that indicates the number of words or word equivalents in the text portion of the message.
This number acts as a control mechanism to verify accuracy. If a relay station receives the message and counts a different number of words in the text than what the check number states, they know an error occurred during transmission and must ask the sending station to repeat the message. The check ensures the message is relayed accurately.
