LZ是一个新手ham，希望尝试卫星通联，但是发现比如在比较热闹的iss上，大家报的又快又挤，我要么是听了一半忘了一半，要么是听到了过后还要默念一遍确定完整呼号是啥，感觉这样基本和通联无缘了，想请教大家怎么练习或者有什么技巧。

放在22年我可以说多听多练，放在现在我只能说力大砖飞（

不管别人如何，准确的报出自己呼号，如果你抄收不了，就说汉语让他们慢一点，他们不慢你就继续CQ

@"BG7OIY"#p97952 FM卫星通联是这样的🤣现有的FM卫星过境时间都短，比如ISS一般只有10分钟。所以语速快可以尽快结束QSO，让出宝贵的过境时间窗口给其他ham参与，是一种善意。我的建议是： 1、熟悉字母解释法。做到别人报出单词，你心里马上反应出对应字母是什么。标准字母解释法优先，其他常用解释法备用（有人上星也会用）。 2、每次上星录音并回听。上星听不懂无非一是语速快跟不下来，二是碰到非标解释法，三是英语口音不适应（比如大部分JA台）。其实跟外语听力有点像，多听听，习惯这种语速，另外对常见的非标解释法加深印象。觉得他台报呼号快的地方和听不懂的地方，放慢到0.75倍速反复听两遍。 3、实际上星时碰到语速快的他台，抄不清呼号又想呼叫，可以守听一个QSO回合，听下和其通联的对方怎么重复呼号的，如果能抄清另一方复诵呼号且他俩QSO了，那你“照方抓药”即可。 4、常上星的话，会对活跃台的呼号、说话声音有个基本的印象，可以辅助判断。有时听到的QSO速度巨快，其实是因为双方都是老熟人，有“声纹识别”，自然语速就上去了🤣 另外，二楼的朋友BG5GDP上FM星时报呼号非常新手友好，吐字清晰，碰到他可以尝试呼叫，也许会是你的第一个FM星QSO😊 -

@"BH2VSQ"#p97954 不不，他问的是怎么解决“大家报得又快又挤”的问题，先得解决“快”的问题。解决了“快”，“挤”的问题也能解决一部分，剩下的才交给QRO力大砖飞。

@"BI3BXB"#p98008 不不不，现在问题是你想回他，首先你得能上去，管你升级天线还是升级设备，先收到，再能上去，然后才要考虑其他问题（

@"BI3BXB"#p98008 如果人太多的话基本上要么上云台指向准，要么手持+QRO，不然你是完全上不去的，之前五五值机的时候就存在这个问题，同一场人特别多导致如果你主控功率小或者天线偏差一点信号强度不够就完全上不去，完全抓瞎（

正常的，你可以先重复后三位，然后随着次数的增多你的记忆能力和抄收能力会得到质的飞跃。现在卫星圈风气很恶臭，遇到嘴贱的人不用受他影响，只要你做的事不违法卫星通联规则，就没问题。

@"BH2VSQ"#p98019 嗯你说的是一个痛点，拿k6上星的我也很有体会。不过从楼主问的问题看，缺的还是上星熟练技巧。上星技巧+硬件设备组合起来达到好的通联效果，后者花钱升级设备和天线就行，但前者还是需要时间练习不是嘛。楼主这一阶段可能更需要的是前者的加强，不然上星也是🐲……

如果是确定下行他说的已经清晰，但是你的耳朵脑子和嘴没跟上的话，就报后三位就行，剩下的回去查录音。还有就是不要去反应解释法单词对应是什么字母，比如听见alpha beta charlie，不要浪费时间去想这仨字母是啥，直接无脑鹦鹉学舌，念出阿尔法贝塔查理就行了，至于他倒是是啥字母，把这件事交给事后查录音。以上能够提高很多效率并且可以解决部分耳脑嘴颗粒度没对齐的问题😎

How can I effectively use satellite communication?

BG7OIY

LZ is a beginner ham radio operator who wants to try satellite communication. However, he found that on busy satellites like ISS, the signals are very fast and crowded, making it difficult to listen properly. He either forgets what he hears or has to repeat it mentally to make sure he has the correct call sign. This makes it almost impossible to communicate effectively via satellite. He is asking for advice on how to practice or any tips that might help him.

BI3BXB

BG7OIY Here's how FM Satellite Communication works:🤣The current FM satellite passing times are very short, for example, the ISS typically only has 10 minutes. Therefore, speaking quickly allows you to complete a QSO as soon as possible and make way for other hams to use this valuable passing window, which is a considerate gesture. My suggestion is:

1. Be familiar with the letter-to-word association method. So that when someone says a word, you immediately know what letter it corresponds to. Prioritize the standard letter-to-word association method; other commonly used methods are available as backup (some people use them even during star calls).

2. Record and listen to each broadcast every time. If you don't understand a particular broadcast, it's usually because the speed is too fast, the explanations are unconventional, or the English accent is unfamiliar (as with many JA broadcasts). This is similar to listening to foreign language audio; just keep practicing and getting used to the pace. Also, familiarize yourself with common non-standard explanations. When you find a section where the broadcast call sign is mentioned and you don't understand, slow down to 0.75x speed and listen repeatedly twice.

3. In practice, when I encounter a station with a fast transmission rate, it's difficult to copy the call sign and also make a CQ call. The best approach is to listen for one QSO round, observe how the other party repeats their call sign, and if you can successfully copy their repeated call sign and have established contact, then simply follow that pattern.

4. When you frequently contact the same station, you will develop a basic impression of their call sign and speaking style, which can aid in identification. Sometimes, when you hear a very fast QSO, it's actually because both parties are familiar with each other, allowing for a natural pace based on "voice recognition."🤣

Additionally, a friend on the second floor, using the callsign BG5GDP on FM Star, has a very beginner-friendly setup with clear transmissions. If you encounter him, you might try to make contact – it could be your first FM Star QSO.😊

BH2VSQ

If I were to say it back in 2022, I could say "listen and practice more," but now all I can say is "power and bricks flying."

BI3BXB

BH2VSQ No, he was asking how to solve the problem of "everyone reporting quickly and crowding in," and the first step is to address the issue of "speed." Once that's solved, the problem of "crowding" will also be partially resolved, leaving the remaining issues for QRO to handle.

BH7GUL

BH2VSQ 这话没毛病

bg7xwf

Regardless of what others do, accurately state your call sign. If you can't get a clear read, ask them to speak slowly in Chinese; if they do, continue using CQ.

BH2VSQ

BI3BXB No, the problem now is that you want to reach him. First, you need to be able to get there, regardless of whether you upgrade the antenna or the equipment. Once you can get there, then you can start thinking about other issues.

BH2VSQ

BI3BXB If there are too many people, you essentially have two options: either use a crane to aim precisely, or use a handheld setup with QRO (Quick Radio Operation). Otherwise, you won't be able to connect at all. This was a problem that occurred during the previous "Five Five" event, where a large number of participants meant that if your power output was low or there was even a slight antenna misalignment, the signal strength would be insufficient and you wouldn't be able to connect at all.

BI3BXB

BH2VSQ Exactly, you've hit on a key issue. I can relate to this, as many people who have tried to get their K6 connected to Starlink also find that they lack the necessary skills and experience. While upgrading your hardware and antenna is an option, it requires spending money. However, developing the necessary skills through practice is still essential. In this stage, the most important thing for you is to improve your existing skills.🐲……

BD3QID

Normally, you can first repeat the last three digits, and as the number of repetitions increases, your memory ability and copying ability will experience a significant improvement.
Currently, the atmosphere in the satellite community is quite toxic. If you encounter someone who likes to gossip or spread rumors, don't let their words affect you. As long as your actions comply with the rules of satellite communication, there will be no problem.

BG2LHM

If you've already determined the direction is down, and what he said is clear, but your ears, brain, and mouth haven't caught up yet, just report the last three digits. Then go back and check the recording. Also, don't waste time trying to figure out which letters correspond to words like "alpha," "beta," or "charlie." Just parrot what you hear – say "alpha beta charlie" – and then let someone else investigate later by checking the recording. This will significantly improve efficiency and help resolve any issues where your ears, brain, and mouth aren't synchronized. 😎

BH2VSQ

BG2LHM It seems I'm not the only one who does this. It's completely effortless; I just repeat whatever I hear someone say (x).

BG2LHM

BH2VSQ Exactly, it's just mindless parrot mimicry; the rest can be handled by recording, and then you can investigate later. Haha.😃

BG7OIY

Thank you all, I've learned a lot.😋

BG2GQG

I previously created a mind map about FM satellites, which I hope will be helpful. Additionally, when working with satellites, polarization needs to be considered. You can watch the video by BH7FBP for more information. I wish you success soon.

BG7OIY

BG2GQG Thank you, friend station, for the detailed map! I'm curious about how you determine which grids are rare. Sometimes, it feels like I don't even hear ham operators report their grid information after transmitting their callsign.

BI3BXB

BG7OIY Firstly, based on the call sign, for example, DL4EA (a German amateur radio operator) who used the Bhutan call sign A52EA in Thimphu in late May, if I hadn't encountered this specific prefix before, it would definitely be a rare and valuable license. Secondly, mobile operators often announce their travel plans and planned contacts online in advance. By monitoring social media updates, you can usually find out about these plans beforehand (although they typically don't specify the grid location; at most, they might include a "/" followed by the zone number).

BG2GQG

BG7OIY It's quite simple: when a group of people are chasing someone and shouting, there's likely a story behind it.

bg7xwf

Suffixes do not have callsign properties.
Ultimately, everyone has their own preferences for different types of fast food.
Achieving high connectivity speed is one aspect, while "showing off" (likely referring to boasting about hardware) is another.
Of course, if everyone could minimize their use of B4 communication
Amateur satellites in orbit are quite reliable, so there's no need for high speeds.
