5.6 FEC Mode Operation

The FEC method of error correction is used when there is more
than one receiving station, and no replies are required by the other
station. Each message is sent twice, the characters of the first mes-
sage interleaved with those of the second. The receiving station
thus has two chances to receive each character correctly. If both
characters are in error, an asterisk (*) is printed.
