前几天咸鱼300弄了个YL3040，那么问题来了，滑环应该买什么型号的呢。。。有淘宝链接吗

没必要转到限位后会自己拧回来滑环损耗老大了大不了多留点馈线冗余

真的要实现360°无限旋转吗

云台300，滑环200，换控制板150，家人们谁懂啊😭，云台还没配件贵家人们无语死了无语死了😭

@"Syryia"#p52984 家人们谁懂啊谁懂啊

@"LoseHu"#p53062 滑环成本确实比较高，YL3040一般自带控制板，用RS485就能控制。我就是用的YL3040无限旋转的云台，云台顶载设备箱和天线。设备箱随云台一起运动，这样就无需担心缠线的问题。设备箱中放UVK5和树莓派。用树莓派转发远程控制频率指令到UVK5。UVK5的音频也通过树莓派转发到手机或者电脑上。 UVK5的固件使用的是[quansheng-dock-fw](https://github.com/nicsure/quansheng-dock-fw),电台控制指令通过自编软件->hamlib->[QuanShengDock](https://github.com/nicsure/QuanshengDock)->树莓派->UVK5 指令转发周期比较长，期待大佬在losehu固件上增加控制指令，实现写频线控制UVK5。如果模拟FT-991等电台指令就更好了，这样常见的卫星追踪软件就能控制UVK5了。期待您的回复。 BD8ARF敬上。

@"BD8ARF"#p60418 太牛了，是一个很好的思路，但是使用方法感觉还是有点小众

滑环确实损耗大在DTric的群里很多大佬也在研究

@"BD8ARF"#p60418 可不可以问一下大佬是怎么是实现改装的？能不能详细展开讲一下

就3040来说，不配滑环 🤣 另外，你真的需要滑环吗？滑环可能主要解决的不仅仅是绕馈线这么简单的点，还有防水密封等场景，但是要付出的就是插入损耗。或者能在滑环后面安装双向放大器，抵抗这部分损耗。还有，3040如果不改驱动板，150M以下可是有强干扰的。

YL3040 RF sliding ring

LoseHu

A few days ago, I bought an YL3040 for 300 yuan on Xianyu. Now the question is, what kind of sliding ring should I buy? Are there any links on Taobao?

Is it really possible to achieve 360-degree infinite rotation?

LoseHu

PTZ 300, pan/tilt unit 200, replacement control panel 150, anyone know what these are?😭The tripod itself isn't expensive, but the accessories are.
Everyone was speechless.😭

BD8ARF

LoseHu The cost of slip rings can indeed be quite high. The YL3040 typically comes with a control panel, and it can be controlled using RS485.

I am using the YL3040, which has unlimited rotation. The mount includes a device box and an antenna. The device box moves with the mount, so there is no need to worry about tangled wires. The UVK5 and Raspberry Pi are located in the device box. The Raspberry Pi forwards the remote control frequency commands to the UVK5. The audio from the UVK5 is also forwarded to a phone or computer via the Raspberry Pi.

The firmware for UVK5 uses:quansheng-dock-fwRadio control commands are transmitted via
Self-written software ->hamlib->QuanShengDock->Raspberry Pi ->UVK5
The command forwarding cycle is quite long. I hope that someone can add control commands to the losehu firmware to enable UVK5 frequency control. Ideally, if it could also emulate FT-991 or other radio commands, then common satellite tracking software would be able to control the UVK5.

Looking forward to your reply.
Respectfully submitted, BD8ARF

Syryia Hey everyone, does anyone understand?

LoseHu

BD8ARF It's really great; it's a good idea, but I feel like the way it's used might be a bit niche.

BH3HSI

BD8ARF Could you please ask the expert how to implement the modification? Could you also provide a detailed explanation?

LoseHu Help: losehu0126.packed.bin I have a K5 v2 and I want to flash it!

The slip ring does indeed cause a significant amount of power loss. Many experts in the DTric group are also researching this issue.

BI1NIZ

Regarding the 3040, it does not come with a sliding ring. 🤣

Additionally, do you really need a sliding ring? Sliding rings may not only solve the simple issue of cable routing, but also waterproof sealing scenarios. However, there is an insertion loss to consider. Alternatively, you could install bidirectional amplifiers behind the sliding ring to mitigate this loss. Also, if you don't modify the driver board on the 3040, it can experience strong interference below 150 MHz.

Cherish life, stay away from 3040.
