This is a pseudo-”VOX” 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. No signals will be heard during the spaces
between dots and dashes
(
unless the sending speed is extremely slow
)

Full break-in
(
also known as “Full QSK”
)
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 frequency, while you are in the midst of a transmission.
