When a dispatcher uses the code 10-40, what are they asking?

The code 10-40 is used by dispatchers to inquire about how well their radio transmission is being received. This communication is essential for ensuring that both the sender and recipient have a clear understanding of the information being communicated, which is crucial in transit operations where safety and efficiency are priorities.

When a dispatcher asks this question, they are effectively ensuring that the line of communication is clear, confirming the quality of the transmission, and allowing for effective coordination between the dispatcher and the personnel on the ground. Understanding the clarity of communication can help prevent misunderstandings that could lead to errors in operations or safety concerns.

The other choices represent different inquiries but do not align with the specific meaning of the code 10-40. For example, asking for a location or for police assistance would require different language or codes entirely.
