What does the code 10-01 indicate?

• A. Unable to copy
• B. Signal good
• C. Location
• D. Acknowledgement/Message Received

Answer: (A)

In two-way radio communication, mesh of quick statuses is conveyed with 10-codes. The number after the dash indicates the current condition of the transmission. 10-01 specifically means you cannot copy the message clearly—reception is not intelligible due to noise, interference, or a weak signal. The appropriate response is to ask the sender to repeat, check your equipment, and try to retransmit on a clearer channel. Other options don’t fit this code because a good signal is described by a positive code (often 10-2 or 10-4 depending on the agency), indicating the message is received clearly. Location codes are typically 10-20, identifying where you are. An acknowledgement or message received is commonly 10-4, signaling the transmission was understood.
