我想在学校申请一个关于无线电的社团，有没有什么不需要操作证，花费少（每人小于100元），最好是比较有趣的的项目啊？

你可以组织学习无线电知识和祥光法律法规，组织体验sstv接收。你已经拥有执照、呼号、操作证，这样你的社团成员可以在你的带领下学习及实践。

天线制作，组织考证训练，观摩实操，学习CW技能，都可以的

SWL，弄点集体收听卡，指引新同学发卡/收卡（有些成员可能之前对邮政知识一窍不通，借机实践）

来泼点冷水 1 学校申请社团挂靠考试或系部找好没有 2 如何与审批的领导介绍此爱好 3 社团人数如何保证其他的暂时没想到活动的话其实你可以参考一下一些科普馆或者亲少年宫的活动，组装接收机收听cw信号什么的（网上买套件）

@"BG7XSS"#p79624 APRS气球是业余无线电比较放飞自我的有趣玩法。不过考虑到它需要发射APRS信号，**本质上是一个信标台，仍然要考证+设台审批。** APRS气球有成熟的开源方案（github.com/lightaprs 下面的几个项目，可以用太阳能电池片或电容/小电池供电）虽然它载荷很轻，加上氦气球本身，整体质量仍然低到不属于《施放气球管理办法》所称的”气球“范畴，原则上不需要报批审核。但还是得考虑一下不要太靠近附近机场，避免影响民航等飞行器秩序。有一些工具测算气球大致漂流路径（在它因为空气稀薄而爆掉之前）。我记得这玩意在欧洲比较流行，那边APRS网关多（

What projects can amateur radio clubs set up?

BA4TAQ

I'm interested in starting a radio club at school. Are there any projects that don't require a license and cost less than 100 yuan (approximately $15) per person, preferably something interesting?

You can organize learning about radio knowledge and relevant laws and regulations, as well as experience SSTV reception.
You already have a license, call sign, and operating certificate, which means your club members can learn and practice under your guidance.

BG5CVB

Antenna fabrication, organization-led verification training, observation of practical operations, and learning CW skills are all possible.

Playing LoRa

BG7QVU

SWL, obtain some QSL cards for group listening, and guide new members to send/receive cards (some members may not be familiar with postal knowledge, so this is an opportunity for them to practice).

Send APRS balloon

BH5UNT

BG7XSS APRS balloons offer a fun and relaxed way for amateur radio enthusiasts to experiment with APRS. However, considering that they need to transmit APRS signals,In essence, it's a beacon tower, and still requires verification + installation approval.
There are mature, open-source solutions for APRS balloons (such as the projects on github.com/lightaprs, which can be powered by solar panels or capacitors/small batteries).
Although the payload is light, and combined with the helium balloon itself, the overall weight remains low enough that it does not fall under the definition of "balloons" in the "Regulations for the Management of Balloon Release," so it generally doesn't require approval. However, it's still important to consider avoiding flying too close to nearby airports to avoid disrupting air traffic, including civil aviation. Some tools can estimate the approximate flight path of the balloon (before it bursts due to thin air).
I remember that this technology was quite popular in Europe, where there were many APRS gateways.

Let's cool things down a bit.
1. Students attempting to use a school's facilities for exam preparation or seeking assistance from a department without proper authorization.
2. How to introduce this hobby to your approving manager.
How can we ensure that each group has the appropriate number of members?
There are no other options currently being considered.

In terms of activities, you can refer to some science museums or children's palaces for inspiration. You could assemble and receive CW signals using a receiver (you can purchase the necessary components online).

With the support of the class teacher and the geography teacher, it now depends on whether the principal approves.

BH5UNT

不需要操作证的话，意味着不能在业余段发射。以收听为主。
无线电测向？接收天线可以由社员低成本地自行DIY，除了发射机（信标）的持有者外，其他人不需要考证。
或者是接收卫星下传的的SSTV图像（使用泉盛等廉价机型，卫星过境时间不一定和社团活动时间重合）
收听
或者DIY FM接收机等（BD6CR出过一些有趣的套件，用直插元件，不过需要一定焊接能力）
或者可以和校园广播站合作（这个大概得依靠一点小人脉），观摩无线广播发射设施，学习射频-音频链知识。
也可以购买一些轻巧的免执照的公众频道对讲机（功率0.5W那种），测试通联距离等。

BH5UNT Thank you.
