Does anyone have a basic guide on how to setup up limesuite to use FFTViewer? I am trying to do some basic scanning to find my car keys signal
I would use sdrangel or gqrx or sdrconsole or anything besides LimeSuiteGui. Unless it is LimeSuiteGui you are trying to master.
If you want to use LimeSuite you can go through this test guide:

qspectrumanalyser is very easy to use, IMO
There’s also one that may be well suited to your task since you can record and then analyze with some nice builtin features.
