Reverse engineered UV-K5 schematics These are extremely incomplete and inaccurate schematics me and others have made for Quansheng UV-K5 radio. All seen here is based on looking and measuring the radio PCB. These files are here mostly for my own convenience and to make it possible for others to complain about inaccuracies. This does not have a corressåonding PCB yet, because I did not care for it.
If you want to reverse some segment of the PCB:
- Join and ask questions in the UV-5K Dev Telegram group.
- Check if a sheet for the subsection already exists.
- Add a new sub sheet to the top level schematic sheet for your segment.
- Name it, use no spaces.
- Annotate your schematic with "First free after sheet number X 100"-option in Kicad.
- Pullrequest that file or whatever.
