Which of the following describes full break-in CW (QSK)?
- AAn operator must activate a manual send/receive switch before and after every transmission
- BStations wishing to break in must send the Morse code signal "BK"
- CIncoming signals are received between transmitted dots and dashes
- DAutomatic keyers are used instead of hand keys
Correct answer: C — Incoming signals are received between transmitted dots and dashes. From the official ISED question bank, verified word for word.
Why
Full break-in, or QSK, means your radio switches so quickly that you can hear other stations between the tiny dots and dashes you are sending, allowing for natural conversation without waiting for a full pause. The full explanation — and one for every question — is in Pro.
