[49] Flipper Zero - Jeeves teaches RF Modulation
In this video, Jeeves teaches us all about RF modulation!!! The butler gives a simple explanation of ASK, OOK, 2FSK, 4FSK and GFSK modulation! Learn AM bandwidth as Lassie barks to high frequency tones. By the end of the video, you will understand the differences between these modulations. We also learn what the Flipper SubGHZ configure means when you select a modulation of AM270/AM650 & FM238/FM476.
I've tried to keep the tones fairly low frequency, so hopefully you are able to hear all of them throughout the video.
In a future video, we will look at how to update your Flipper Zero firmware to support any of the modulations from this video, which could allow you to clone custom remotes that are currently not getting captured when you use the SubGHz Read RAW feature.
A future video will also use RF Waterfall instead of dice -- where the color represents the amplitude of the signal & left is lower frequencies than the carrier and right is higher frequencies. Once you have watched this video, you should be able to look at a waterfall signal and tell which modulation is being used & what deviation/bandwidth are needed to receive the signal.
