之前间接的了解过蛙鸣，pixie，丢丢机这三种简易小电台，希望自己能够DIY一个，请问各位大佬有无开源文件或开源电路板资料，如果有其它类型的简易自制qrp小电台，也请各位大佬不吝赐教😘

蛙鸣和皮鞋网上有电路图啊，根据电路图画板找嘉立创打几块 PCB 就好啦。实在不行就买一个套件自己回来逆向呗。

原版pixie谐波抑制很差，杂散超标，不能上照，别的不太清楚，应该能好点

丢丢机是纯发射机，杂散可过检测，我自己画的一个复刻版： https://oshwhub.com/nyara/cpk4

@"BG2KAJ"#p41306 大佬，您的复刻版打不开呀

@"BI1UDG-711"#p41301 好的，感谢提醒😄

@"BI7LVX"#p41294 OK，准备试试😄

丢丢机荣老师有卖套件吧，其他类似的QRP当然usdx了

@"Syryia"#p41320 膜KSR😋 刘老师的新版usdx什么时候能发车呀

I would like to ask about questions related to "frog calls", "Pixie", and "Didi".

BG2MEM

I've previously been familiar with the Frog, Pixie, and Droop QRP radios. I'm hoping to build one myself. Could any of you experienced individuals share any open-source files or circuit board designs? If there are other types of simple DIY QRP radios available, please let me know.😘

BI7LVX

You can find circuit diagrams for frog croaking and leather shoes online. You can then use the diagrams to order PCBs from JiaLiChuang, or if that doesn't work, you can buy a kit and assemble it yourself.

BG2MEM

BI7LVX Okay, let's try it out.😄

BI1UDG-711

The original Pixie harmonic suppression was very poor, with excessive stray emissions that prevented it from being used. I'm not sure about the other aspects, but it should be improved.

BG2MEM

BI1UDG-711 Okay, thank you for the reminder.😄

BG2KAJ

The "Didi" device is a pure transmitter; it can still be detected, and this is my own replica version that I drew.

BG2MEM

BG2KAJ Hey, your replica doesn't seem to be working properly.

BG2MEM

Syryia Membrane KSR😋
When will Professor Liu's new version of USDX be released?

BG2MEM

Syryia Received😘

BI9CBD

Could you please tell me which model of "Doudou" device it is?🍑And🐟I couldn't find it.
