UHF CB Transceiver
Operation - Special Features
Lead-in Delay (Ld)
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 causes 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 longer Lead-in Delay helps to stabilise both the
communication link from your radio to the repeater station and from the repeater station
to the other radio.
