Do you know the six misunderstandings of radio?

Date:Jan 18, 2021

Misunderstanding 1: Setting up and using radio stations without authorization


The radio stations mentioned here mainly refer to handheld walkie-talkies and car radios for personal use; don’t think that you can install and use radio stations at will. It should be understood that the signal emitted by any radio station must occupy the radio frequency, just as each broadcast program needs to occupy a separate frequency. If the radio frequency is illegally occupied, it will cause radio interference. Radio frequency, like land and mineral deposits, is an important resource of the country and is managed by the country. To set up and use a radio station, you must submit a written application to the local radio management agency in advance, get approval and issue a radio station license, before it can be used legally and normally.

To set up and use a radio station in a dedicated radio communication network, you must apply to the local radio management agency in the name of the unit to use your own or group dedicated frequency. Pay frequency resource occupation fees, equipment testing fees and other related fees in accordance with national regulations. If you find interference from other radio services on the approved dedicated frequency, you can appeal to the radio management department for protection.

In short, it is illegal to set up and use a radio station without obtaining a radio station license.


Misunderstanding 2: The technical parameters of the station cannot be changed without authorization even after obtaining the radio station license


Even if you have obtained a radio station license, the radio station cannot be used whatever it wants. Improper use of radio stations may cause interference to other radio services, which will not only infringe other people's normal communications, but even cause serious disasters unknowingly. For example, some people who have obtained amateur radio licenses ignore the restrictions on the frequency points approved by the radio regulatory agency and choose to use other frequency points in the unapproved 430-440MHz amateur frequency band without authorization. Amateur radio is a secondary service in this frequency band, and other important services such as aeronautical navigation and radio positioning are also used in this frequency band. If the frequency is used indiscriminately and severely interferes with aviation communications, it may cause a major accident. Based on the relevant flight records, the relevant authorities have determined that it was caused by the frequency indiscriminate use by your radio station.

Some people think that the unauthorised choice is an idle frequency that cannot hear other radio signals so as not to interfere with others, but it is not. Different services use different working methods, equipment performance, and coverage. The inability of your equipment or your listening ability to hear the signal does not mean that the frequency is idle, nor does it mean that your signal will not cause serious interference. For example, some parts of the amateur frequency band (such as: 145.800-146.000MHz and 435.000-438.000MHz, etc.), which also include internationally recognized satellite transponder frequencies, although you can’t hear the signal, the satellite But you can receive your signal and normal satellite communication is destroyed, but you may not know it at all. In the same way, your signal, which does not appear to be very strong on the ground, may also cause non-negligible interference to the communication of the air plane that is just right at your antenna to emit the largest lobe. Therefore, even if you have a radio license, you must work on an approved frequency and comply with the frequency rules recognized by the amateur radio community. Using an unapproved frequency is also illegal.


Misunderstanding 3: Set up relay stations for small groups


Some groups set up permanent or temporary radio relay stations without authorization in order to expand their communication coverage. It should be noted that relay stations are also a type of radio station. Generally, relay stations have high antennas, high power, and greater influence. Unattended, it is easy to cause out of control problems, so the harm is more serious than the general unauthorized use of walkie-talkies, and it must be banned. According to regulations, amateur radio enthusiasts can use amateur frequency relay stations, but they must be installed by legal amateur radio associations or related units, and the units that set up stations must improve the management system and have the function of remote switch.


Misunderstanding 4: Applying for a radio station license without following the communication rules


Amateur radio enthusiasts have world-wide uniform statutory or customary norms for radio communication. For example, only internationally assigned radio call signs can be used as radio station identification. The call sign must be reported when communicating, and other names or codes must not be used instead, and the content of the communication must not be used. Involved in politics, religion, profit, privacy, no secret language, code word, no uncivilized language, no entertainment, teasing, playing music, etc. If you do not abide by these regulations, do not learn the relevant technical and legal knowledge, in the communication, you will not use the legal call sign but use your own code, vehicle number, vulgar language, jokes and even play music and songs; use your own device "card" "Taiwan, building a platform" deliberately interferes with others; violations of rules and conventions in the use of frequencies and the application of courteous terms will only put oneself in a position that everyone despise, and the relevant departments of such black sheep will never turn a deaf ear to it.


Misunderstanding 5: Hand-held radio walkie-talkies can be used at will


Some people hear the misinformation and think that handheld walkie-talkies can be bought everywhere, carried with them in the car, and used at any time. This is a behavior lacking the most basic radio knowledge. People who illegally use walkie-talkies in many places in my country (including individual users and hotels, construction sites, service places, etc.) have been subject to confiscation of equipment, fines, etc., and should be taken as a warning.


Misunderstanding 6: I used the radio illegally and nobody controlled it?


Compliance with radio regulations involves respecting and complying with national regulations, not occupying national frequency resources indiscriminately, not infringing on the lawful use rights of others, not disrupting the order of radio waves, and using one's own actions to avoid potential accidents caused by communication interference, so as to protect others legally Interest is the basic quality of a person. One must abide by the principles and not rely on the whip to go the right way. If you consciously abide by the law, your noble image will educate and drive more novices through the airwaves and become a role model in people's minds on the frequency, so that you can live in harmony with the social environment. But if you know that the law is illegal and you refuse to change it, the radio monitoring department, public security department, and national security department will definitely notice you. Therefore, if you have a good radio station, you have to cooperate with people who consciously abide by radio laws and regulations and have good quality. Only by driving into the misunderstanding can you become a true radio enthusiast.
