Q) What type of identification is being used when identifying a station on the air as Race Headquarters?
A) Tactical call
During events such as Bike-a-Thons, marathons, and parades, tactical call signs are often more useful than regular call signs. "Milemarker Five" and "Finish Line" are more descriptive in these situations. Remember that all stations must still ID with their FCC call signs every 10 minutes.
