Well, I first saw this video 2 years ago, but I just clicked save without much interest. And after all these years, I'm finally glad I didn't skip this video XD By the way, is there any chance I can email him to ask about some of the problems I'm encountering?
11:40 Hacker looks at waterfall spectrum graph: "wow, look at that LoRa signal!" Machinist looks at waterfall spectrum graph: "wow, look at that nasty cross-threading!"
Excelent analysis!! Congratulations. There are some things I need them to be cleared out a little more. 1. Seems that each figure is encoded into a single chrip. Right? But in the image shown in minute 12:55 looks like there are at least 3 frequency jumps within a chirp period. Why did that happen? 2. In the next slide the chip rate is defined as dF/dT, having unit of 1/s^2. But, according to documents it is calculated as BW/2^SF, which have units of 1/s. So it seems that a better definition of chirp rate would be #chirps/s. What do you think?. I can see this video is 3 years old, so maybe it was cleared long ago. Thank you!!!

'I couldn't get it to work'
It's such a relief not to feel alone
