What amateur radio lovers do on the radio

Amateur radio novices should pay attention to these things and do not do them randomly.

Recently, many friends have consulted through comments or private messages how to get started with amateur radio, how to get an amateur radio operation certificate and apply for a radio license, etc., today I will introduce in detail some of the places that need to be paid attention to in the introduction of amateur radio, especially novice friends, which things are best not to do.

1. Amateur radio equipment shall not be used illegally.

For amateur frequency band stations (including handheld walkie-talkies or car radios), you need to apply for a legal radio license to use, and the station operator needs to have the corresponding level of operation certificate. Many people feel that they buy a walkie-talkie, or borrow a walkie-talkie from a friend, and then they can launch and use it at will, which is very wrong.

For professional radio stations, it is necessary to apply to the relevant administrative authorities separately for formalities, which does not belong to the content here. Here is also recommended for everyone, you can also join your local amateur radio association, there will be many enthusiastic ham in the association to help everyone answer various questions, generally speaking, prefecture-level cities will have their own radio associations, some counties are likely to have radio laughing mountain enthusiasts association, you can also search on the Internet, generally speaking, it is the name of the place + radio association for the keyword search.

2. Do not make calls at will.

Some friends have their own call sign after obtaining their own operating license to handle the license, but many people have a call sign, thinking that they can call at will on the frequency, which is a very bad behavior, because before you initiate a CQ or designated call, you need to listen on the frequency, confirm that no one uses the frequency, before you can call, otherwise you will disturb the normal communication of others, and it will inevitably cause others to be disgusted with you.

3. Do not use other people's call signs at will.

The fraudulent use of another person's call sign is a very wrong act, and the degree of error will not be repeated here, except for the guest launch, of course. Some friends are likely to have some understanding of amateur radio before obtaining their own call sign, and are more familiar with the norms of communication, and feel that they can use other people's call signs to communicate on the frequency, but they do not know that this behavior is illegal.

Fourth, it is not allowed to transmit high-power at will.

At this stage, there are strict requirements for transmitting power in different frequency ranges in China, many people think that increasing the power will obtain a better communication effect, but excessive power will affect the surrounding electromagnetic environment, so in the case of using amateur radio equipment, please follow the national regulations on the maximum transmitting power of the frequency.

Fifth, do not indulge in amateur radio too much.

Here it is also recommended that everyone arrange their spare time reasonably, and the investment in amateur radio should also be moderate, fully consider the economic affordability and their own daily use range, and reasonably purchase radio equipment.

One layer of meaning is that amateur stations are stations that support amateur bands – stations that support (including) the 430-440 band, and professional stations that support some other specific frequency bands.

The other layer means that the function of amateur radio stations focuses on "playing", and adjusts various related parameters, including: adjusting the transmitting power, searching for the frequency points with signals, storing multiple different frequency points, manually changing the stored frequency points at any time, adjusting different noise suppression values, and having a signal strength meter. The professional radio station pays more attention to the stability of use, so the complexity of the operation is relatively low, and the performance requirements such as the durability of the battery and the stability of the transmission power are higher.

In contrast, professional stations usually cannot adjust the transmitting power at will, do not have the function of searching for frequency points, can store a small number of frequency points, and can only display the channel number but not the frequency value. It requires a computer and special software and a cable to adjust the frequency and related functions stored in each channel, and there is usually no signal strength meter to display.

According to the provisions of the national "Interim Measures for the Management of Individual Amateur Radio Stations": (excerpt) Article 2 Amateur radio stations are radio stations set up by amateur radio amateurs for the purpose of testing transceiver equipment, conducting technical training, communication training and competitions. Only those with receiving equipment are amateur reception stations.

Article 3 Amateur radio stations are divided into collective radio stations and individual radio stations. Radio equipment is set up by the group, and the user of the group setting up the station is the collective radio station. Radio equipment is set up by an individual and is used by the individual as a personal radio station.
