Decoding Car Key Signal

Hi, I'm trying to understand the signals obtained when locking/unlocking my car in order to understand how things work internally. So far I have done the following: - Capture the signal: I've used HackRF + GnuRadio to capture the signal and store it into file. radio1.png - Then I've analyzed the sig...

Re: Low Frequency Antenna

1A. Yes you can use either of those antennas, and the red thing is the antenna. Preferably I would like to solder the wires inside the cable to some kind of connector in order to connect to the WHITE connector of the antenna as presented here - so I can easily connect/disconnect the antenna without...

Re: Low Frequency Antenna

Hi, thank you for a detailed answer. You've specified a potato/loop antenna that can be used. However, I'm looking for an antenna that I can buy (I don't wish to make my own antenna at this state), which is also compatible with HackRF/SpyVerter.

However, we've never...
