Describe the bug

Hello, I obtain the "HF antenna is UNUSABLE" when I run the "hw tune". I have tried with 2 antenna (Iceman collection):

It's look like some component leaked here. Where can I found schematics and part number to try replacing them?

You would need to ask Proxgrind about that. Closing, since its not a issue related to this firmware repo.
