Amateur radio direction finding (ARDF, also known as radio orienteering and radiosport) is an amateur racing sport that combines radio direction finding with the map and compass skills of orienteering. It is a timed race in which individual competitors use a topographic map, a magnetic compass and radio direction finding apparatus to navigate through diverse wooded terrain while searching for radio transmitters. The rules of the sport and international competitions are organized by the International Amateur Radio Union. The sport has been most popular in Eastern Europe, Russia, and China, where it was often used in the physical education programs in schools.
ARDF events use radio frequencies on either the two-meter or eighty-meter amateur radio bands. These two bands were chosen because of their universal availability to amateur radio licensees in all countries. In the UK events with somewhat different rules are also run on 160 meters. The radio equipment carried by competitors on a course must be capable of receiving the signal being transmitted by the five transmitters and useful for radio direction finding, including a radio receiver, attenuator, and directional antenna. Most equipment designs integrate all three components into one handheld device.

Famous quotes containing the words amateur, radio, direction and/or finding:
“I have been reporting club meetings for four years and I am tired of hearing reviews of the books I was brought up on. I am tired of amateur performances at occasions announced to be for purposes either of enjoyment or improvement. I am tired of suffering under the pretense of acquiring culture. I am tired of hearing the word “culture” used so wantonly. I am tired of essays that let no guilty author escape quotation.”
—Josephine Woodward, U.S. author. As quoted in Everyone Was Brave, ch. 3, by William L. O’Neill (1969)
“England has the most sordid literary scene I’ve ever seen. They all meet in the same pub. This guy’s writing a foreword for this person. They all have to give radio programs, they have to do all this just in order to scrape by. They’re all scratching each other’s backs.”
—William Burroughs (b. 1914)
“Your Englishman, confronted by something abnormal will always pretend that it isn’t there. If he can’t pretend that, he will look through the object, or round it, or above it or below it, or in any direction except into it. If, however, you force him to look into it, he will at once pretend that he sees the object not for what it is but for something that he would like it to be.”
—James Agate (1877–1947)
“The lion cares less about being king of the beasts than about finding his dinner.”
—Mason Cooley (b. 1927)
