I was just sitting here ruminating, and remembered something I'd read in some Ham magazine a millennium ago, about how phase modulation is easier to do than FM, but they wrote that it has a "tinny" sound.
Anybody wanna discuss that?
I was also thinking about the spectrum you can see on a 'scope when you use an RF sweep generator with the sweep fed into the X axis (horizontal, instead of the 'scope's own sweep), and the output goes to the Vertical. That's fun, too. :-)
