Ok so I don’t know why this has never tripped in my head before seeing all these posts but something about reading it for the 10000th time just set me off, so now I have to clarify this command… so read this and understand:
• hw tune tells you the tuning of your antennas
• hw tune does NOT actively tune your antennas
You don’t need to run it each and every time you power up your proxmark3. You should only really ever run it if you change antennas or connect a new unknown antenna, just to be certain your shit is connected correctly before running any commands.
