I've been out of the hobby for a few years and just getting back in. That said if these communications C4FM, DMR, etc are nothing more or less than VOIP solution protocols are you comfortable with the fact that if you don't have an Internet connection all of this goes away? At least that's my understanding. If that's true, then much of the purpose of HAM Radio was to provide communications in disaster scenarios....thus being independent as FM is, these protocols are fully dependent upon an Internet connection. Have I got that correct? If not, school is now open!
