Semi-break-in
This is a pseudo-”V2;” mode used on CW, whereby the closure of the CW key will engage the transmitter, and
release of the key will allow the receiver to recover after a short delay. 1o signals will be heard during the spaces
between dots and dashes unless the sending speed is extremely slow).
Full break-in
Full break-in also known as “Full QS.”) involves very fast switching between transmit and receive, incoming
signals may be heard between the dots and dashes as you send them. This allows you to hear a station that sud-
denly starts transmitting on your freTuency, while you are in the midst of a transmission.
