Radio Sport: a Serious Business

1. In Russian vocabulary the electronics enthusiasts are known as "radio sportsmen". Radio sport is a highly organized, serious activity supported and administered by the government. The organization responsible for administering radio sport is called the Radio Sports Federation. In radio sport, the key word is competition. The highest award, one held by a relatively few sportsmen, is "Master of Radio Sport". One particularly interesting form of radio competition is called "Fox Hunting". This is a contest in which teams of "hunters" (young people carrying portable direction finders) race against time² to find "foxes" (hidden transmitters). The rules call for³ the three "foxes" to take up positions one or two miles apart in a large wooded area. At the starting signal, the "foxes" begin identifying themselves by voice announcements⁴ at one-minute intervals, each "fox" therefore being on the air⁵ once every five minutes. The announcements, which are very brief, are made on amateur bands⁶ by means of low-powered transmitters, usually homemade. The winning "hunter" is the one who first locates all three "foxes" in sequence⁷. The kind of competitive spirit⁸ that characterizes radio sport is typical of electronics in general. Whether it be the technological state of the art, TV via communication satellite, or techniques for electronic training, the our people are fully aware of the importance⁹ of communications-electronics in the space age, and they intend to remain competitive in every possible way.
