What is the Q code indicating that you want the other station to send slower?
- A QRN
- B QRS
- C QRM
- D QRL
Correct answer: B — QRS. From the official ISED question bank, verified word for word.
Why
QRS is the correct signal because it literally means "send more slowly," telling the other operator to reduce their sending speed so you can copy the message clearly. The full explanation — and one for every question — is in Pro.
