HF antenna is UNUSABLE

[cletifer]

I just bought a brand new out of the box Proxmark3 RDV4.01 with Blueshark from Hacker Warehouse while folding the Guide on this github page and running the hw tune command I noticed the HF antenna is unusable and am looking for some help troubleshooting this. I have double-checked the screws on the antenna as well.

You're looking for hf tune

Issues here are solely about source code. Your issue seems to be related to HW. Join the discord server and ask there.

Meanwhile, flash bootrom aswell.

@iceman1001 can you provide me the link to get to the discord?

Its in the readme of this repository.
