True or False: when using the HF ALE the operator should use normal radio call sign procedures, per existing SOP and not the three number identifier (e.g. 012).

• A. True
• B. False
• C. Not Specified
• D. Both

Answer: (A)

Using HF ALE doesn’t change the requirement to identify with your standard radio call sign according to SOP. ALE automates link establishment, but you still must follow normal identification practices—start with your customary call sign and use it for all transmissions, as your logs, accountability, and regulatory compliance rely on it. The three-digit numeric identifier is not the default form of identification in routine operations; it may exist in some specific internal addressing schemes, but it can create ambiguity, complicate logging, and violate standard procedures unless the SOP explicitly allows it. So the correct approach is to adhere to the normal call sign procedures per SOP when using HF ALE.
