One key differentiator: bandwidth is fundamentally limited in radio.
- jcims 5y agoThe bandwidth is not only extremely limited, it’s shared over an enormous range. When you key the mic on a good 80m transmitter, you’re claiming that little slice of spectrum for a million+ square miles. I think a lot of the new applications of digital modes would avoid conflict by starting off up in the 5 to 10 GHz range and work its way down.
