I'm here to help you out.😃
Let me briefly introduce FM Star, and I'll write a basic overview now, with a more comprehensive beginner-friendly guide coming later.
- Go to Bilibili and watch some videos.
First, I need to understand how satellites communicate with other systems. During my undergraduate studies, I uploaded some videos on Bilibili (not involving any illegal activities; the focus was on creating high-quality subtitles), and at that time, the call sign was still in the 5th zone:https://space.bilibili.com/361119581/channel/collectiondetail?sid=1394354Now, I have the capacity but not the strength.
- Software
The software can be downloaded from https://s.seeku.site/ A commonly used software for amateur radio enthusiasts in China (Look4sat, Android version) typically involves using a handheld Yagi antenna to point at the satellite. This requires you to go outside and manually aim it towards the approximate location. As for using an automated mount, that's a different story, as I haven't tried it yet/crying.
- Call sign and alphabetic notation explanation
After watching the video, you should now realize that understanding the explanation of letters is quite important.
In practice, my suggestion is to keep the content as short as possible (not to make the speech very fast; some friendly stations have spoken very quickly in the past, including myself, which was based on a situation where everyone was very familiar with each other during a previous broadcast).
As for the brief reason, I think it is
- The satellite repeater's signal is weak and intermittent; you need to shorten your transmission so that others can clearly hear your call sign. Otherwise, they may only be able to hear half of it or just a few letters.
- Due to the large number of people, there is not enough space for others. In 2024, domestic FM communication is not very good, and many times two people are unable to complete a connection before someone else interrupts (even if they hear that two people are in the process of completing the connection). Also, QQ satellite groups (95339567(Click to join) The atmosphere has become a bit difficult to describe; last year, the discipline was good and everyone was polite, waiting for everyone to connect before joining.
Several short-range CQ (calling) methods:
- BD8CWG (Explanation of the callsign)
- CQ BD8CWG (Explanation of callsign)
- CQ satellite BD8CWG (Explanation of callsign)
If there are few people on the satellite and the signal is good, you can freely communicate, even having a conversation with others like making a phone call.
When you're just starting out, it's best to remember the last 2/3 digits of the other person's call sign, then state what you remember, followed by your own call sign, and ending with "59 73 over" (which is a common way to say goodbye).
Antenna
Regarding antennas, with good conditions, the stock antenna on the handheld radio can work (verified), but a directional Yagi antenna is still needed to achieve a better experience. It can be made yourself, and it's actually very simple to do. You can also buy one from BH2RSJ (which many users recommend). You can find them on Xianyu and QQ groups.
Radio
UV dual-stage
Frequency
Some commonly used FM frequencies, as well as some satellite repeaters (e.g., UVSQ, I7), may be activated at certain times. When practicing, pay attention to the Doppler effect (changing channels in the video is a fine-tuning of frequency). You can ask about this in the group; there's also a frequency table in the group. Generally, for the Doppler effect, satellites passing through are divided into five stages, and 5 frequencies should be stored on the radio.
When should I adjust it?
- Based on the software's trajectory, approximately how many times does the position need to be adjusted?
- If you find that the audio on the radio is no longer clear compared to before, adjust it.
Event
In group chats, members typically share information about special events like SSTV. If someone doesn't share, they can simply ask the group beforehand.
Call sign data
When participating in satellite communication, it is generally recommended to register on QRZ.com. Although the website's Chinese interface is not user-friendly, adding your call sign data to the database can make it easier for others to find your contact information and connect with you for friendship and QSL card exchange. Adding your call sign requires posting in their forum and requesting an administrator to add it, which can be a bit cumbersome; however, you can also ask about it in the group.
Please note that some radio stations are not friendly towards our country or have individuals who are difficult to deal with. It is also important to be aware that these stations rarely respond to calls (this is very rare).
When starting out with amateur radio, it's helpful to familiarize yourself with some common call signs used on the air. This can make completing QSOs (contacts) much easier.
- lotw
LOTW is the ARRL's logging system. Since the website is currently down, we will not discuss it for now.
I just thought of this, and I hope it helps. The key is to join a group and take action. Learn through practice, identify problems, and solve them. Also, learn from others in the group (even if you don't speak up, you can still learn a lot from the other members).
