swimmingcat Sending two or more messages at once is usually done in "expedition mode." The method I'm referring to is a workaround for sending "two messages per cycle," and it's mostly accidental (for example, after finishing a connection and transferring to CQ for a few seconds, you might realize there's another station that needs to be contacted, so you change the message being sent during the transmission cycle). No one intentionally uses this method to improve efficiency (it would just lead to exhaustion).
