Chain
Selects the chain. The Loran chains are groups of transmitting stations that use timed radio pulse
transmissions. In each of these chains there is a master station and two or more slave or secondary
stations. Stations belonging to a same chain transmit pulses in timing groups: a different time base
identifies each chain. The time base of each chain is the Group Repetition Interval or GRI. This GRI
identifies the chain in unique mode. For example the GRI = 4990 identifies the chain of Central Pacific
zone. The default setting is 9970.
