Re: LF antenna and ampflication. How?

LF antenna and ampflication. How?

Hi all,
I am new on sub MHz frequencies and have a small project as receiving 100kHz-150kHz band signals and amplify this signal to another receiver. Which devices and setups should I have? I have a budget around 100 USD and need a portable solution. Any help appreciated!

Re: How to copy car key fob?

It's not that easy, most car fobs have rolling code security, so once the button is pressed the code changes. You need the official IC with the rolling code algorithm programmed in by the manufacturer and they probably won't give that to you. Probably the only way would be to purchase a second keyf...
