11.6 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 message 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.
