At first, I was just looking around on the web for some simple Rules of Thumb
that compare the weak-signal performance of commonly used analog and digital
modulation types. I was mostly focused on FT8 and FT4 but I also wanted to

did find a number of good articles that compared some but not all of them.
This article is my attempt to aggregate the available information into
something easy to understand.
