1、The NaNo VNA portable vector network analyzer needs a version with a screen that costs around 200 yuan, which is sufficient for testing antennas.
2. Batteries: Aim for around 400 yuan (RMB) for lithium-ion or iron phosphate lithium batteries, and try to seek advice from experienced local HAM enthusiasts. Avoid impulsive purchases on Taobao (Chinese people don't cheat each other).
3. If you are a newcomer, please abandon the idea of using less than 100 watts. This is not because I don't support domestic products, but rather a sincere suggestion.
4. If you are a newcomer, don't think that you can use the dormitory windows to transmit shortwave signals.
5. Based on items 3 and 4 above, the antenna can be a portable GP pull-out or end-fed, allowing for field operation in sports fields or parks outside of school, as well as in green spaces within the school, ensuring you have a relaxing afternoon.
6. If you already have a NaNo VNA, you can temporarily slow down the process; it's not an immediate necessity.
7. Equipment: If you don't want to use CW or FT8, for beginners, 100 watts, 100 watts, 100 watts – that's important! The FT-891 is a good choice and retains its value well. You can bring your own antenna analyzer and power meter, and it has digital DNR noise reduction. After graduating from university and buying a car, you can install it in the car, and then take it home to use.
8. Due to limited funds, consider purchasing used equipment from a certified testing machine vendor (provided that the previous owner did not have it tested by the Ministry of Industry and Information Technology).
9. Don't be afraid of the procedures required by the Ministry of Industry and Information Technology (MIIT). As a university student with a home address in location A and school in location B, crossing provincial boundaries, and having fully prepared "national no fixed residence" application materials, it should not be difficult for a university student to write an attachment four. After all, wouldn't you have to write your graduation thesis?
10. If you can obtain a scholarship, have two girlfriends, and resolve the above issues easily, this will truly bring you happiness and avoid arguments and sadness with your girlfriend…
11. If you've read this far, and are still considering machines with power output of 20 watts or less, then you might want to explore alternative paths (buy – use – connect – in-depth learning, or directly quit). Of course, if your environment is excellent, with no interference and a good antenna, QRP machines can also be used. It all depends on whether you can tolerate being alone.
With online registration, I've seen many experiences of college students and enthusiasts. Regarding shortwave radio, it shouldn't be treated like UV radiation, where you can easily control everything.
