What does the Q signal “QSL” mean?
The correct answer is C: I have received and understood. The Q signal 'QSL' means 'I have received and understood'. This is used to acknowledge receipt and understanding of a message or information. For amateur radio operators, this is a standard acknowledgment. Understanding this helps when operating CW or using Q signals. 'QSL' is also used to mean 'I will confirm the contact' (QSL card).
Exam Tip
QSL = I have received and understood. Think 'Q'SL = 'Q'uery 'S'ignal 'L'ogged (acknowledged). Means 'I have received and understood' or 'I will confirm the contact.' Not about speed, already confirmed, or previous contacts.
Memory Aid
"QSL = I have received and understood. Think 'Q'SL = 'Q'uery 'S'ignal 'L'ogged. Means 'I have received and understood' or 'I will confirm the contact.' Standard Q signal for acknowledgment."
Real-World Application

Key Concepts
Why Other Options Are Wrong
Option A (Send slower): Incorrect. 'Send slower' is 'QRS,' not 'QSL.' QSL is about acknowledgment, not speed.
Option B (We have already confirmed): Incorrect. This isn't the standard QSL meaning - QSL means 'I have received and understood' or 'I will confirm,' not 'already confirmed.'
Option D (We have worked before): Incorrect. This isn't what QSL means - QSL is about acknowledgment or confirmation, not about previous contacts.
