Antenna Problems?

Hi everyone.
I wanted to see if anyone else is having problems with different hardware versions of proxmark?

I have had a Proxmark3 Easy for a while and I have only just received my new Proxmark RDV4.
I cloned the v4.9237 tag from the RRG github and built both RDV4 and PM3OTHER firmwares and flashed both Proxmarks.

I began testing with some cards and wristbands I have laying around. This is where I found strange results.

The PM3Easy and RDV4 both work correctly on HF cards.

Its when I try LF T5577 I get mixed results.

The RDV4 works great, but the PM3Easy has trouble detecting T5577 cards. Some cards work, some don't.

Whats the best way forward from here?

PM3 Easy:

Re: Antenna Problems?

ok,  do  a  lf command first like,

lf read 
hw status


And I tell you haven't followed some instructions for your RDV4...
Read and follow the instructions here.

Re: Antenna Problems?

I have now also added the keys and upgraded the sim module on the RDV4. Thanks for the heads up.

Re: Antenna Problems?

your devices and antennas looks good from where I can see it.
If you get better results with official repo on your easy,  then maybe you should keep running official repo on it.
