I have found a library of Infineon RF transistors developed in QucsStudio 2.5.7. I want to use them in the latest QucsStudio 4.3.1 but the program simply says the .sch files are incompatible; no suggestions for how they might be updated? If anyone has any ideas, I would be grateful for your feedback.
Version 3.3.3-light is now available on the download page. It can be used to convert old schematics and data displays. Just open them and save them. After this, they can also be opened by the most recent QucsStudio version.
