Does this observation have both 4k8 and 9k6 packets?

kng commented 3 months ago

yes, I split the yaml in two with one baud per file. the preamble is distinctly different, between the two. as is the inter-symbol interference.

daniestevez commented 3 months ago

Good point about the inter-symbol interference being different. I hadn't noticed that.
