Contest Club Ontario (CCO) is Ontario's
entry into International Club competitions in the 21st Century,
providing one vehicle to highlight Canadian participation in these
It brings together the talents of a large
number of Amateur Radio contest operators in Ontario who may now focus
on a common goal, in addition to traditional individual competition.
Formed in July 2002 with only 16 members it had grown to 35 members by
the end of August of that year. In 2007 CCO membership broke the 200
mark and counted over 275 members in its tenth year.
CCO participates in over two dozen events
during the year, some involving two or three contests. Most use HF CW
and phone but RTTY and VHF are also featured in many events. Member
scores are collected by the Secretary and submitted for Club
Competition, putting Ontario contesters head-to-head with other such
clubs in Canada, the United States, and worldwide.
