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.
