Contest numbers are often padded with leading zeros to help the receiving station catch the number and avoid needing to repeat it. The leading zero is sent as a cut number, T. Otherwise, cut numbers are not used in contest serial number exchanges. For each four-digit number, try to head-copy it. First, the number is sent in Morse code. Then it is spoken. And finally, it is sent again in More code. If you missed it the first time when it was sent, the second time allows you an opportunity to learn the words.
