McKinney Amateur Radio Club was formed in February 1968, and became McKinney Amateur Radio Club, Inc when the Articles of Incorporation from the State of Texas were received on September 4, 1979. The initial meeting was held at the Collin County Bank on N. Tennessee street, one block north of the downtown square. Following meetings were then held at the Texas Power & Light Company, located two blocks West of the square on W. Virginia Street, in downtown McKinney. Initially, club membership fees were $10.00 per year.
