(c) Third and fourth characters
These characters denote the report number assigned to the message by the coast
station where the message originated.

received at a character error ratio of 4% or less. When an incoming message has the
same identification code as one already stored in memory, it will not be printed.

code is not held in memory and messages are printed each time they are received.
