What do you mean by platform, platform seedling, hand microphone, switch head and car charger?

1. "Yes, yes, yes?" This is a very impolite way of addressing, which is equivalent to "Can friends copy?" When you meet this kind of phone call, just ignore it!

2. "Insert" is used to apply for inserting other people's conversations. This phrase should be used with care. This call should not be used when the frequency is idle. When someone is connected, try not to interrupt unless you want to join their topic or have something very urgent! And after plugging in, return the microphone to the friend with the original frequency connection;

3. "73" as the conclusion, as a general greeting, male and female friends or couples can also use "88" to represent love and kiss;

4. "Signal 59+" signal report, the previous numbers represent the semantic understanding degree conveyed by the other party, and it is entirely possible to understand the meaning of the other party without any background noise, while 1 means that the other party can't understand what he is saying at all, and the background noise completely drowns out the sound; The following 9 represents the received signal strength, 1 the lowest, 9 the highest, and the signal with 59+ represents the best signal quality;

5. "Cover the table and clamp the table" refers to malicious interference. People who launch illegally use high-power equipment for a long time, which interferes with normal communication. The correct abbreviation is "QRM"

6. "Miao Zi" and "Bangzi" refer to different antennas. Miao Zi refers to the car antenna, and Bangzi refers to the vertical antenna on the base.

7. "Uplink" refers to the transmission frequency? So a ham said to someone in the relay race, "I copied you." How did he copy it to the difference frequency relay? Are there two tables open at the same time, set at different frequencies? Uplink refers to the transmission frequency. It is not difficult to copy the uplink. Many devices have REV function, which is called "frequency inversion", that is, the transmitting and receiving frequencies are reversed, and the uplink signal can be seen. If there is no frequency reversal function, we usually set the two frequencies after the relay frequency to 1, which is the direct transmission of relay 439.750, and the other 1 is 434.750.

8. Is "insert" written like this? What do you mean? I heard that some signals are interpolated. How to interpolate? Differential function is similar to relay, that is, signals received at one frequency are automatically forwarded to another frequency. In addition to professional relay stations, generally radio stations with differential functions, such as FT8900r and TM-V7a, only support differential conversion of different frequencies, that is to say, differential conversion can be done between different frequency bands, such as U/V differential conversion, which simply means that the signal difference of 0.7 meters is transferred to 2 meters.

Does 9.900M mean mobile phone? Why did Ham say that? Why don't you talk on your cell phone? Besides major, what other stories are there? 900MHz is the working frequency of the GSM mobile phone we usually use, so there is no specific meaning, just a convention.

10. "You have 20% background noise", how do you know it so accurately? Is there a watch on the counter to see how much it is? You don't have a hand platform, do you? This percentage is based entirely on personal experience and is not precisely defined or set for measurement. Therefore, the signal report about background noise is for your reference only, because the source of background noise itself is not necessarily caused by your emission, but is related to the receiving position and the condition of his receiving equipment. For reference only, don't care too much about this parameter.

11."BG1XXX, please come here", why do you say "come here"? I didn't leave. Did Ham say this statement himself or translated it in English? What is this? Inviting a ham is to hand over the microphone to someone, which means please send the voice, because there are many people on the frequency and there may be many friends waiting for the call. This expression mainly means that you are calling someone and asking him to return your call.

12. "Copy", also known as "stir-fry" and "completely copy", means to fully hear each other's voice and understand each other's meaning.

13. "Microphone modulation system" refers to the reduction degree of sound when it comes out of the microphone. When the modulation system is normal, it's basically my voice. If the modulation system is low, the sound will feel stuffy, and in severe cases it will feel like the sound from a jar. When the modulation degree is high, the sound will be sharp, and sometimes even split, which may be accompanied by sharp noise similar to that received by a microphone. Sometimes we call low modulation system "cold microphone".

14. Generally, when using relay equipment for communication, we all use different transmitting and receiving frequencies. The frequency difference between the receiving frequency and the transmitting frequency is called "difference frequency", and the difference frequency is divided into upper difference and lower difference. Generally, we use low difference, that is, the transmitting frequency is lower than the receiving frequency. Take Beijing Relay as an example: the transmitting frequency is 434.750 and the receiving frequency is 439. We call it the difference of 5MHz, which is the setting method of ordinary amateur radio stations, because the difference frequency of some amateur radio stations is fixed, which is 5MHz. Of course, there are also some places where the difference frequency is set to be special, such as Shijiazhuang relay, which seems to be set to 9.850MHz.

15. "Ham" and "sausage", "Ham" comes from English ham. Ham became the abbreviation of amateur radio enthusiasts because there was no international unified call sign in early radio activities, and the call sign was basically made by himself. Harvard University in the United States has an amateur radio club, and its member is Elbert. Hyman and Barber. Ham means ham in English, so it evolved into "ham" in China. "Sausage" refers to friends who have not formally joined amateur radio organizations but also like radio sports.
