@ancarda Yeah, built upon the command-line app rtl_power, cheers! Been really fun building it, though a bit messy since this was my first time really giving Swift a good go (best way to learn is by building a project right?). I've fixed the issue you found, now if you don't have rtl_sdr installed it will open but tell you off, I'll improve the error message at a later date (I'm ill right now so I'm not gonna be writing documentation lol). The aesthetics of the preferences window are gross but there's not much else I can think of doing with it.
