This is really cool. And it has such a great readme with screenshots and everything.

One thing I can't figure out from a cursory reading is what type of RF hardware would be needed to use this?

I was just thinking about finding some software like this is because I have lost one of the keyless entry key fobs for our car and I was thinking if I could record and replay the signal from the car, I might be able to narrow down the fob location.

I suspect it is in the house somewhere. But we have a 1 year old who loves to pick things up and insert them into any slot or box he can find.

Basic receive-only SDR is for example the famous RTL-SDR, which you can get for ~$50 with a dipole antenna. It's a USB dongle, and it will get you to surprisingly many interesting places despite the low price tag.

In order to transmit you need some slightly better hardware, such as the HackRF. Replaying a signal with a HackRF is really easy. Note that technically you're not allowed to transmit without a license, whereas reception is generally lawful, with very few exceptions (looking at your legal scar tissue, UK). The author of HackRF published a nice, though not yet completed, tutorial series on YouTube.

There's a lot of activity in the spectrum, if you like to tinker with things then definitely get an SDR, some of the best entertainment value per dollar for a hacker :)

How new is this project? It was really surprising to see something published in 2022 that still attempts to offer Python2 support, and all the baggage that will carry.

ELI5? what can a user do potentially with this framework? detect drones?

edit: wow i just saw the lecture video and this seems like a tool that lets you detect/analyze radio frequencies emitted from almost any device (?) and lets you emulate the packets (?) or wave patterns to manipulate the data it sends out?

this seems like a really powerful tool. I wonder if you can open car doors with this. Also wouldn't this mean that this tool could become illegal as a result?

Is software that can open car doors illegal? Why?

Also, opening car doors isn't as simple as repeating a signal you captured(in general)

That said, capturing the car's question when you press the button on the door, amplifying it in the direction of the nearby fob, and then capturing and amplifying the fob's response would work for some systems.

Your "edit:" portion just describes an SDR, a software-defined radio. They're pretty common these days actually.

This tool is an advanced front-end for such hardware, kinda like Wireshark is an advanced front-end for a networking controller. It does look pretty cool.

Is there any list of supported hardware?

I can't believe it actually worked. Took like 5 hours to build all of those components haha
