'''[[QSK operation (full break-in)|QSK]]''' – "I can hear you during my transmission" – refers to a particular mode of Morse code operating often called [[QSK operation (full break-in)]] in which the receiver is quickly enabled during the spaces between the dits and dahs, which allows another operator to interrupt transmissions. Many modern [[transceivers]] incorporate this function, sometimes referred to as ''full break-in'' as against ''semi-break-in'' in which there is a short delay before the transceiver goes to receive.<ref name="CIOS">{{cite web |url=http://jcs.dtic.mil/j6/cceb/acps/acp131/ACP131F.pdf |title=Communications Instructions Operating Signals |date=April 2006 |publisher=[[Combined Communications Electronics Board]] |access-date=2014-05-16  |url-status=dead |archive-url=https://web.archive.org/web/20120906015123/http://jcs.dtic.mil/j6/cceb/acps/acp131/ACP131F.pdf |archive-date=September 6, 2012}}</ref>
