The McKinney Amateur Radio Club (MARC) has been operating for over 50 years, and is an ARRL affiliated Special Service Club with roughly 150 active members.  In 2018 MARC celebrated our 50th anniversary of affiliation with the American Radio Relay League (ARRL).  Our documentation indicates that the MARC/ARRL affiliation began on February 14, 1968, but the affiliation may have actually begun much earlier. 

MARC is dedicated to serving the greater McKinney, Texas and Collin County amateur radio community by operating several voice and APRS repeaters, providing amateur radio license classes, FCC Volunteer Examiner ham radio testing sessions, communication services for public events, and monthly technical training sessions. MARC’s main operating activity is the annual national Field Day event, where amateur operators set up field stations using emergency power, to test their emergency preparedness. The club operates a weekly information net on Sunday at 8:00 PM local time on the 146.740 FM repeater (tone 110.9).
