That’s pretty much intentional.
I wanted to keep it clean and show only the actual filters, the bias-Ts are pretty much what you’d expect and its entirely optional for the actual functionality.
If you carefully read the Readme and click the schematic link, it should take you to the pdf of the full schematic.
Only it doesn’t because the links that work in my gogs do not work for kitspace.
Might need to talk to someone about that.
