Lead-in Delay
Lead-in Delay is a SELCALL transmission parameter that "wakes-up" and helps the receiver of the other radio to lock onto the incoming signal. Each time a SELCALL ID is transmitted, the Lead-in Delay attaches itself to the beginning of the code sequence and cause the transmitter to be on for a longer period prior to the code transmission. This makes for a stronger communication link between the transmitter and the other receiver.
One major advantage to having the longer Lead-in Delay is when selectively calling another radio via a repeater station. A long Lead-in Delay helps to stabilize both the
communication link from your radio to the repeater station and from the repeater station to the other radio.
