What is the trick to winning first place in the radio direction finding competition 80 meters

I think it still depends on strength, you can first turn up the sound to the maximum end, and then turn it up until you can hear it, and then turn around, there is a place where there is no sound or the sound is very soft, there is the direction of the stage, and finally you need physical strength, you must run fast, otherwise you will waste a lot of time. If it rains, you can also look at the footprints, and if there are many footprints, there may be a signal source there.

Technical and physical fitness, a little bit more. In the game, if you start in the middle or start from the back, you can see how much the plant is stepped on, you find a station to find the vicinity, there will generally be a referee, to see if there is anyone nearby to rush to a place, or someone stands in a daze, or the plant is seriously flattened, you have to pay attention.

In addition, before the start of the game, you can measure the direction of the radio station with your teammates, and the distance and distance. If you have been to the venue before the game, you can still guess the approximate location.

I think the most important thing is that your machine has a one-way function. In 09, I have always been the first in school training, but our training is generally just a big circle, and I can guess the place, so I have always been the first in the machine without a one-way machine. The scope of the Luxian competition is too large, and I go in the opposite direction with the dumb point method, I don't know how long it will take, and I am planted in the wrong direction.

You have to choose a machine that has a one-way approach.

In the radio direction finding competition of 80 meters, you win second place and you get the first place.

The Radio Direction Finding Pivu Championship is a sports competition organized by the Radio Direction Finding Sports Association by finding a signal source that can emit radio waves. The competition is the radio direction finding level, and the contestants look for the transmitter through the radio direction finder to find the specified number of units within the specified time, and the one who uses it for less time wins.

Radio direction finding movement, also called"Radio Fox Hunting"It is one of the competitive sports, which is a combination of modern radio communication technology and traditional hide-and-seek games, and the activities that achieve the purpose of competition by finding a small signal source (i.e., transmitter) that can emit radio waves.

The general process is as follows: in the wilderness, hills and other natural environments, several signal sources are hidden in advance, and the prescribed telegraph signals are sent out at regular intervals. Participants held a radio direction finder to measure the direction of the concealed radio station, and ran a certain distance on foot to quickly and accurately find out these signal sources one by one.

The winner is the one who finds the specified number of units within the specified time and uses it for less time.

The radio competition is divided into two groups of people to search for a thing in the grass or anywhere, this kind of thing will emit electromagnetic waves, and then pass, radio reception, this kind of competition is timed, to see which group of people find more in the end to win, this competition is imported from abroad, and now it is also very popular in China.

This is a trendy movement in recent years, which is to make use of the radio ratio.

Here, in the early years, primary and secondary schools were still conducting radio direction finding competitions, but later they stopped doing it because it was too much of a toss.

Radio direction finding is the use of 80m band short wave, with 0 10 more than one radio, arranged in parks, mountains and forests and other trees with more complex (but not dangerous) terrain suitable for the competition venue, hidden. As a rule, hidden in the bushes, the antennas tend to take an inconspicuous tan and are hung from trees. Each station constantly emits Morse code.

sound, the number of the radio station.

Within the specified time, the contestants start from the starting point, use the side machine to find each station one by one, check in after finding it, and finally find the finish line (usually Radio 0) to report. The results of the competition are based on the shortest time of the contestants who found all the radio stations, and the number of radio stations found shall prevail if they do not find all of them.

There are multiple referees in the competition venue, who are mainly responsible for observing whether the players play according to the rules.

The principle of the direction finder: the built-in magnetic rod antenna, when the magnetic rod is perpendicular to the direction of radio wave propagation, the signal received is the strongest, Morse code.

The loudest the sound, the closer you are to the radio station during the run, the louder the sound, and the radio station is found.

Players are trained to familiarize themselves with each station's Morse code.

Master the skills of finding a desk.

In 1962, the first national championship was held in Xiangshan, Beijing. As a result, the radio direction finding campaign was gradually carried out throughout the country. In 1979, Henan took the lead in resuming radio direction finding activities, and various provinces and cities carried out them one after another.

In 1980, the National Sports Commission officially listed it as a competition event. It was also listed as an official event of the National Games in 1987 and 1993. The private sector has also held many times such as:

West Lake Cup", "Peacock Cup" and other forms of activities. The good connotation of radio direction finding has become more and more popular among the masses and has attracted the attention of all sectors of society. In 1993, the State Sports Commission, the State Education Commission, the China Association for Science and Technology, the Communist Youth League, and the All-China Women's Federation jointly issued a call for:

The radio direction finding campaign was launched among young people across the country, and it was decided that five companies would be the organizers to hold the National Youth Radio Direction Finding Championship every year. So far, radio direction finding has been widely carried out throughout the country, with hundreds of thousands of young people participating in different forms of radio activities, and nearly 1,000 people participating in the annual National Youth Championship.

At present, there are two main types of radio direction finding activities carried out in China: one is short-distance direction finding that is suitable for popularization in primary and secondary schools. It can be carried out in parks, campuses, suburbs with many trees and pleasant scenery, with a total distance of several hundred meters.

Every year, the National Youth Radio Championship jointly sponsored by the General Administration of Sports of the People's Republic of China, the Ministry of Education, the China Association for Science and Technology, the Communist Youth League and the All-China Women's Federation is carried out in this project, and the high school, junior high school, and primary school groups are set up in the competition for male and female individual competitions, team competitions and direction finder production competitions. The second is long-distance direction finding in the 80-meter short-wave band (and 2-meter ultra-short-wave band (144 MHz) that conforms to international rules and is suitable for college and middle school students. The site is selected in an area with undulations of no more than 200 meters and good vegetation, and the total straight-line distance of the five radio stations is 5-10 kilometers.

The National Radio Direction Finding Championship jointly sponsored by the General Administration of Sports of the People's Republic of China and the Ministry of Education of the People's Republic of China is set up every year. In addition, about 10 national youth direction finding divisional competitions are held every year (sponsored by various regions, including Beijing, Shanghai, Nanjing, Wuhan, Changsha, Guangzhou, Qingdao, Wenzhou, Xiamen, Northeast China, East China and other regions) and about 10 national grassroots coach instructor training courses (sponsored by various localities). All provinces and municipalities can also hold competitions of various scales or various training courses according to their actual conditions.

The World Radio Direction Finding Championship is held every even year, and by the end of 2006, Chinese players have won 11 gold, 8 silver, and 8 bronze; The Asia-Pacific Championship has been held five times, with a total of 35 gold, 21 silver and 18 bronze medals. China's radio direction finding team has won honor for the country with brilliant results. China also often sends teams to participate in international competitions held by France, Belgium, Japan and other countries.

Relevant leaders, principals and teachers from the education bureaus of Nanjing, Shanghai, Beijing and other places have formed teams to participate in the competition and achieved excellent results.
