General exam question G2C01
Subelement G2, OPERATING PROCEDURES· Group G2C
Which of the following describes full break-in CW operation (QSK)?
- A.Breaking stations send the Morse code prosign “BK”
- B.Automatic keyers, instead of hand keys, are used to send Morse code
- C.An operator must activate a manual send/receive switch before and after every transmission
- D.Transmitting stations can receive between code characters and elements (correct answer)
WhyFull break-in CW operation, QSK, means the transmitting station's receiver can hear another station between the individual code characters and elements it sends. Full break-in, QSK, means the receiver stays active between the dits and dahs of your own keying, so you can literally hear another station starting to send in the gaps between your code elements, answer D. Sending "BK," using an automatic keyer, or flipping a manual send/receive switch each transmission are all separate things that don't describe what QSK itself actually is.
