大家好啊，我来看看有木有人。这可能有点长鉴于我最近手搓出来了个[6米段电台](https://forum.hamcq.cn/d/7060/58)（自己起的名：HM50S），我想继续降低成本和复杂度，做个可量产款，并支持常用的cw+usb语言/数据，供大家在本就不活跃的6米段增添一点人气。硬件电路上已经想好了一些低成本方案，但还需额外的验证。我在想啊：既然我都给自己做了一个了，有这技术，让更多A类爱好者能玩上6米段岂不美哉。**我也不想当资本家抢市场**，格局打开嘛，靠这个怎么可能发家致富嘞，到顶也比不上找个班儿上的工资高。💰适量就好。这个项目将继续用stm32主控（是我最熟悉的单片机，入门时玩了一下Arduino和esp32,不过已经忘光了），我之前的电台的GUI采用lvgl图形开源库，lvgl代码靠chatgpt随便写了写改了改，它的各类函数我也不熟悉，都靠AI了，现在的界面还是一团糟，其实是我也懒得改。反正软件固件编写一直是一件让我头疼的事。网上其他大佬开源了一些带显示屏的收音机，他们的GUI都非常好看，我不知道他们用的什么图形库，向他们学习。可毕竟之前是我独狼一个人开发，我技术肯定有个上限。这个项目不算是高技术的，硬要我一个人干也不是不可能，但即使这样，我也不再希望一个人干了。身边没啥共同兴趣的人，我口才也是不咋滴，没啥好朋友，无线电爱好本身也小众。现在我想从网上找些志同道合人，一起探索一起开发，应该会很有趣😋。借此多接触些人和资源，阔阔人脉，从大佬那里学习多多技术，说不定能接触到高级仪器呢（现在家里最贵的射频仪器还是300不到的vna和tinysa）。要不是之前心惊胆战的验机一次过，还得跑多几趟无管检测中心用他们那超级无敌26.5G宽带频谱仪检测我这自制机呢。目前呢还没开始上大学，不过快了，未来学习电子工程专业也打算从事这个方向。0%工作经验。希望能提前多了解下社会，多搞搞不一样的事。哈哈，有点像发的来相亲的文案。期待遇到对此项目感兴趣和喜欢_电子/无线电_技术的各位朋友们，不论你是超级大佬还是萌新小白，一起玩嘛。不感兴趣的也来者不拒。当然也不是所有人都能看到这贴子，大家也可以说说意见和提议。如有需要，我可以详细说明这个项目计划以及我目前掌握的东西。美丽的图片 [upl-image-preview uuid=5631eb8b-91f5-42ab-b054-e74f53dff1aa url=https://storage.hamcq.cn/2026-01-05/1767605815-153971-15375375972-66e65a4ab1-k.jpg alt={TEXT?}] 本人也是spacex粉丝呢 [upl-image-preview uuid=d07286de-8bd5-47ec-a095-c4f42b8efda4 url=https://storage.hamcq.cn/2026-01-05/1767606058-208542-earth-spacecraft-elements-this-image-furnished-by-nasa-335224-749.jpg alt={TEXT?}] [upl-image-preview uuid=e26eb511-bd52-440f-808f-b004cf91f020 url=https://storage.hamcq.cn/2026-01-05/1767606843-255992-yzeev28uxbsjgyqrgy4qvh.jpg alt={TEXT?}]

做成套件，除非你去工信部拿到型号核准。

@"ba7ck"#p92506 是得这样，不让售卖成品电台嘛，型号核准个人没点实力也拿不到吧😅

@"[未知用户]"#p92513加个Q吧 2395664087🤪

@"ba7ck"#p92506 哦对，你认为套件应该是怎么样的呢？比如说拆散再自己组装还是电路板上少焊接些原件这样呢

散件就可以，回来自己组装焊接关键元器件及刷入系统。

直接嘉立创开源广场上面开源，散件相当于你只是卖的电子元器件

我也想做设备，苦于没有综测仪，特来支持楼主！

期待成品，想要狠狠玩6m ~~但是有可能拿到成品的时候已经考b了~~

Redesign for mass-producible 6-meter radio segment // Embedded electronics

BG7MEB

Hello everyone, I'm just checking to see if anyone else is here. This might be a bit of a long one.

Given that I recently made one by hand...6-meter radio segment(Self-named: HM50S), I want to further reduce costs and complexity, create a production-ready version, and support common CW+USB languages/data formats. This would allow enthusiasts to revive activity on the 6m band, which has been relatively inactive. I have already developed some low-cost hardware solutions, but they still need additional verification. The idea is: since I've created this for myself, with this technology, why not make it available to more A-class enthusiasts so they can also enjoy 6m?I also don't want to be a capitalist exploiting the market."It's all about having a good strategy, but how can I make money just by doing that? Even if I reach the top, it wouldn't be as profitable as getting a high-paying job."💰Just a moderate amount is sufficient.

This project will continue to use the STM32 microcontroller (which is my most familiar single-board computer; I experimented with Arduino and ESP32 when I was starting out, but I've forgotten all about them), and my previous radio's GUI used the LVGL open-source graphics library. The LVGL code was written and modified randomly using ChatGPT, and I don't understand its various functions; everything is done by AI. The current interface is still a mess, and frankly, I'm too lazy to fix it. Anyway, writing software firmware has always been a headache for me.

Other experienced developers online have released open-source radios with displays, and their GUIs are very attractive. I don't know what graphics libraries they use, so I plan to learn from them.

However, ultimately, I developed this project alone, and my technical skills have a limit. This project isn't particularly high-tech, but even if I were to do it alone, it wouldn't be impossible. But even then, I don't want to do it alone anymore.

I don't have many people around with shared interests, my communication skills aren't great, and I don't really have any close friends. Furthermore, the hobby of amateur radio is quite niche.

I'm now looking to connect with like-minded individuals online, so we can explore and develop together – I think it would be a lot of fun.😋This would allow me to meet more people and access more resources, expanding my network. I could also learn a lot of technical skills from experts, perhaps even gaining access to advanced equipment (currently, the most expensive RF instrument in my home is a VNA and TINYSA costing less than $300). Without the initial anxiety about testing, I would have had to go to multiple test centers to use their super-powerful 26.5 GHz broadband spectrum analyzers to test my homemade device.

Currently, I haven't started university yet, but it will soon. In the future, I plan to study electronics engineering and work in this field. I have no prior work experience. I hope to gain more insights into society and do something different before starting my studies.

Haha, it's a bit like an advertisement for finding a partner. I hope to find someone interested in and passionate about this project.Electronic / RadioTo all my technical friends, whether you're a seasoned expert or just starting out, feel free to join in. Those who aren't interested are also welcome. Of course, not everyone will be able to see this post, so please share your thoughts and suggestions. If you need more information, I can provide a detailed explanation of the project plan and what I currently know.

Beautiful pictures

I am also a fan of SpaceX.

BD8FTC

Incredible!

ba7ck

Create it as a kit, unless you go to the Ministry of Industry and Information Technology (MIIT) to get it approved.

BG7MEB

ba7ck That's how it works; you can't sell finished radio equipment without proper certification, and individuals don't have the resources to obtain those certifications.😅

BG7MEB

ba7ck Oh, right, what kind of kit do you think would be ideal? For example, should it involve disassembling and reassembling the components yourself, or soldering fewer original parts onto the circuit board?

BG2GJJ

The parts can be delivered separately; I will assemble and weld the critical components myself, and then install the system.

BG2GJJ

The open-source components are available directly on the Open Source Square platform, and selling individual parts is equivalent to simply selling electronic components.

BG7MEB

BG2GJJ Understood.😄

BG7PXE

I also want to build equipment, but I'm struggling because I don't have a comprehensive test instrument. So, I'm here to support the original poster!

BG7MEB

BG7PXE Can I also do a comprehensive test?🤣

BG4QBF

Looking forward to the finished product, and wanting to really enjoy the 6m band.

~~However, it's possible that I might receive a finished product that has already failed the test.~~

BG2GFC

How can a low-cost implementation be achieved using STM32 and ADC, as designed by experts?🤔

BG7MEB

BG2GFC The main difficulty lies in finding a suitable mixer.😐The 6-meter band position is somewhat awkward, as the frequencies are too low for most modern integrated transceivers, and they tend to be expensive. It may also be difficult to find them on Taobao.😂"Use an old-fashioned mixer. While they are readily available and not expensive, they have also been discontinued... I saw a circuit called 'Tayloe detector' designed by foreign enthusiasts, which can be implemented using a 1:4 high-speed switch. That's great! It works well in the low to shortwave range, but it can also be used in the 6-meter band, although the sideband suppression effect may be weaker. I will build a test board to try it out. The baseband AD/DA is an audio IC, costing around ten yuan."

BG2GFC

BG7MEB
I specifically checked this out to see if it's like what I was expecting.

BG7PXE

BG7MEB Looking forward to the finished product.

BG7MEB

BG2GFC Absolutely correct!👍

BG2GFC

BG7MEB If I want to implement a single-sideband (SSB) transmit and receive using frequencies of 430 MHz and 144 MHz, can I modify the amplifier and filter circuits accordingly?😵

BG7MEB

That's not feasible at all. The article states that the maximum frequency depends on the transistor switching capability, and 50 MHz is already quite challenging. I don't know if there's a switch capable of reaching such high frequencies, but I suspect using readily available modulators would be more convenient and cost-effective.😅

BH5UXB

BG7MEB When it comes to bipolar transistors, the 9018 from various manufacturers is a good option, with a characteristic frequency starting at 600 MHz.

1:4 High-speed multiplexer mixer (Tayloe Detector), the receiver part of uSDX, and the PicoRX receiver all use it. However, the analog switches (FST3253/SN74CBTLV3253) used in these have the longest switching time, which can be up to 5-6ns. For example, using Texas Instruments' SN74CBTLV3253:
{SN74CBTLV3253 数据手册“开关特性”一章的截图。Vcc=3.3V时，S-A或S-B通道开启时间最长为4ns，关闭时间最长为5.5ns}
When Vcc = 3.3V, the S-A or S-B channel has the longest enable time of 4ns and the longest disable time of 5.5ns. This equates to approximately 45.45 MHz, which is just below the 50MHz band. If you want to directly mix a 50MHz signal using IQ mixing, the performance will depend on the specific components used.

BG7MEB

BH5UXB Thank you, that makes sense. I was indeed planning to use the SN74CBTLV3253. After reviewing your analysis, it seems like achieving this frequency with just that device might be challenging. Would it be possible to use some high-speed logic devices to drive the transistors you mentioned and achieve this frequency?

BH5UXB

BG7MEB 也不一定要用什么“高速逻辑器件”
Si5351或者MS5351 这种时钟发生器就不错。也可以找块频率合适的有源晶振，把50MHz混成 10.7MHz 中频，再接给 Tayloe Detector。
Si5351/MS5351 输出时钟频率最高能有 200MHz，发射部分也许可以直接参考uSDX。不过据说发射功率不变时，频率越高，管子的耐压要求就越高。
