SEMARC Special Event KØA

September 10, 2022

SEMARC will reprise our Special Event commemorating the Airway Beacon System used by early pilots in carrying the U.S. Mail. As we did in 2017 and 2020, the club has secured the call sign KØA.

In 1920, the United States established the North American Transcontinental Air Mail Route. By 1924, ground-based navigation aids were in place. The aids consisted of lighted airway towers mounted on concrete arrows indicating the direction of the next link in the system. In fact, two of the artifacts remain in Minnesota: a concrete arrow which can be viewed in Cottage Grove and a lighted tower in Mounds Park in St. Paul. The ground-based system continued for a number of years before functioning radio navigation in airplanes became common. For more information, visit these websites:

In 2017 the Special Event was operated from the actual tower installation in Mounds Park. This year we will operate from our club station at Fire Station #3 in Cottage Grove, Minnesota.

SEMARC will operate KØA from 1500Z to 2200Z (11:00-6:00 EDT; 8:00-3:00 PDT). Look for us at or near 7.035, 7.250, 14.250 and 18.100.

Update:
A certificate for stations contacting KØA is now available by clicking here.
