What should you do if a CW station sends “QRS?”
The correct answer is A: Send slower. If a CW station sends 'QRS?', you should send slower. 'QRS' means 'send slower' or 'reduce sending speed.' For amateur radio operators, this is a request to reduce your keying speed. Understanding this helps ensure proper CW communication. Always respond to QRS requests by slowing down.
Exam Tip
QRS? = send slower. Think 'Q'RS = 'Q'uery 'R'educe 'S'peed. If someone sends 'QRS?', they're asking you to send slower. Not about frequency, power, or repeating - just slow down your keying speed.
Memory Aid
"QRS? = send slower. Think 'Q'RS = 'Q'uery 'R'educe 'S'peed. If someone sends 'QRS?', reduce your keying speed. Standard CW procedure for speed adjustment."
Real-World Application
You're sending CW at 25 words per minute, and the other station sends 'QRS?' because they can't copy that fast. You slow down to 15 words per minute. The 'QRS?' request means 'send slower' - you should reduce your keying speed to match their copying ability.
Key Concepts
Why Other Options Are Wrong
Option B (Change frequency): Incorrect. QRS doesn't mean change frequency - it means send slower. Changing frequency doesn't address the speed request.
Option C (Increase your power): Incorrect. QRS doesn't mean increase power - it means send slower. Power level doesn't affect the speed request.
Option D (Repeat everything twice): Incorrect. QRS doesn't mean repeat - it means send slower. Repeating doesn't address the speed issue.
