But I have a group of people with analog radios like Baofeng UV5R, who need to communicate in very bad terrain.
I think it will help improve the quality of communication. In that location, full of hills, digital signal have much lower possibilitty of losing its information than analog device, right?
Oh well, you mean Nyquist-Shannon sampling theorem.
When I'm sending two tones with 0 or 1 meaning, it's just a digital information.
