I think about accepting the challenge and boldly solder SMD where I've never soldered before: Doing the Quansheng UV-K5 4732 addon PCB modification myself 🙈

But… before soldering I need to buy the right board to solder, and there seem to be 3 different options as of today: The green one (which consists of a PCB, a conventional through-hole resistor and a tiny SMD capacitor) and 2 orange PCBs of different sizes with different layout (see photos). The green one seems to be most challenging and the orange ones look easier... but I have no idea at all how these 3 options differ in terms of functionality! Maybe one of you has & could share their knowledge / give a recommendation?

Thx et 73 ;)
