Proxmark3 easy problems

Hello @amal or anyone who can help,

This is maybe just an beginner issue but I’m stuck.

I ordered the Proxmark3 easy from DT and today it was in my mailbox. Even it comes with the Iceman firmware preinstalled, I followed the instructions here:

Getting started with the proxmark3 easy - DT Info - Dangerous Things Forum

Everything worked out just fine until I run “hw tune” which told me that the “HF antenna is UNUSABLE”

Here are the results from "hw version"

I checked in the forum and on google for a very long time but wasn’t able to find anything. What am I doing wrong?

What voltage output do you get, when running ‘hf tune’?

it runs and tries a range of voltage something between 20mV and 40mV but it’s so fast and kind of hard to tell

Does the voltage change noticeably it you put a card on the antenna?

if it drops a bit, try to see if you can read it with ‘hf search’

Edit: I see it states 0v in your picture. It should be around 32V, dropping to 30V when presenting a card…

If it was the LF antenna I’d suggest unscrewing it, but the HF is integrated, leading me to believe you have a faulty board :-/

I can’t tell you anything about the voltage on the HF side because it doesn’t work in the first place. Here is the screenshot from the “hw tune” command:

The “hf tune” command is trying to get anything from the HF part of the pm3 by testing different voltages, but this is unsuccessful and the command keeps testing forever.

In the 3. line where you can see [=] 34 mV / 0 V / 0 Vmax the 34 mV part is changing quickly in a range from about 20 mV to about 39 mV(it’s too fast to be precise).

I was wondering if there’s anything in the parameters which disables or enables the HF portion on the pm3. Since I’ve used the latest firmware from:

RfidResearchGroup/proxmark3: RRG / Iceman repo, the most totally wicked repo around if you are into Proxmark3 (github.com)

@amal: Should I write you an pm or an email?

The orange help button in the bottom right of the website is the fastest way to get ahold of them. You can even provide a link to this thread in the description if you want.
