[CQ-Contest] Self-spotting explanation from CQWW blog

[James Cain]

See "Packet With a Purpose," by James D. Cain, K1TN, QST, August 1990, page 54.-- K1TN------*/"The clusters were created for DXing not contesting."/*

This statement is absolutely, 100% wrong. The original Packet Cluster was designed for contesting. If you don't believe me, ask the designers of the original system.
