Awesome-Cellular-Hacking VS urh

Anyway I was reading these articles https://github.com/W00t3k/Awesome-Cellular-Hacking

You don't need a license to explore and have fun.

Cheap, firmware hackable HTs are hawt, in particular the Quansheng UV-K5,K6.

Tons of SDR receivers out there to explore, and many extremely exiting transceiver projects out there also. Just so much:

>> or somewhat expensive and complex SDR

I don’t think that’s as accurate today as it used to be.

On the hardware side there are tons of options very cheaply available - iirc the flipper uses the c1100 (or a number like that) it’s a popular cheap chip and it’s well documented and interfaces easily with arduino.

More accessibly, lime mini SDRs are cheap but there’s quite a few alternatives too.

On the software side GNU Radio is free with decent tutorials - we’re not talking anything like blender levels of difficulty to adopt even if it is a complex domain.

Although on the more accessible side, urh is incredibly powerful given how easy to use it is https://github.com/jopohl/urh

I used the latter to tap into a 2 channel wireless bbq thermometer via a $10 rtl sdr and that was a breeze, an absolute walk in the park compared to when I reverse engineered the flysky telemetry system.

Universal Radio Hacker on Github

you should check out Universal Radio Hacker

Check out URH.

URH can read flipperzero sub files and can export from wav to sub... https://github.com/jopohl/urh

Throw the recording at UniversalRadioHacker and see what it does with it!

I dont have much knowledge on decoding a signal from scratch but try URH - universal radio hacker here. It might be able to do what you need.

It's useful for transmitting digital RF signals to control household stuff, eg. ceiling fans or whatever. You'd want to also look into rtl-sdr and Universal Radio Hacker.
