I'm very envious of the fact that the OP's school has sufficient resources, and I wish them a smooth completion of their project.
As a student with access to the BOX-6, if you want to build one now, it's better to start early. I recommend that all students who are considering building their own BOX-6, including myself and other A-class students, should:
— Start using 6-meter shortwave radios as soon as possible (since they are all part of school clubs).
— Try to obtain funding or find a physics teacher who can help you pass the B license exam.such as fruit kernels that can be listed on the Shanghai Stock Exchange, like those found in seafood markets.At least, if I had money from going to university, I could sell the old computer and buy a better one. If I didn't have enough money, I would ask adult friends or join an association, or wait until after high school exams before researching further.Time-consuming and demanding.Here are some of my initial thoughts:
"Regarding the 'inspection experience' on the Shanghai Stock Exchange, there is indeed a lot of practical knowledge. However, the standards and levels of scrutiny vary depending on the region and may also change over time. Therefore, it is still necessary to independently investigate and coordinate. In my city, I have reviewed dozens of small business licenses in just one year. For example, when I applied for a BOX-6 license on the Shanghai Stock Exchange, I had to submit the application myself, and then the local authorities would review it. After the initial review, if it was rejected, I had to spend time gathering additional materials and resubmitting them. This coincided with the end of the semester exams, so each time I opened the government platform and saw that I had failed. This made me feel discouraged about studying in the evenings (fortunately, my score didn't drop). It took two weeks in total.
Secondly, DIY: not just the cost of parts costing a few hundred yuan – dragging up the BOM and getting a price quote from Jia Li Chuang was already terrifying – but also the tools needed for soldering? How do you measure stray capacitance and antenna standing wave ratio?
And stability: When considering installation in schools, factors such as waterproofing (to withstand heavy rain and typhoons in Zone 7) and the ability to remotely shut down the equipment during periods of inactivity (to avoid public utility costs and ensure safety in public spaces) must be taken into account.
