Lots of RVers like to talk to folks. even if those folks are half way around the globe :). Ham Radio good for that.
TO tell you all about Ham Radio would take me.. A long time and I type fast so I will give you this www.arrl.org That is your starting point From there you can find area ham clubs and classes and testing sessions and resources....
Ham radio covers all manner of electronic communications
Simple voice.. I do that, AM FM and Single Side band
Digital voice.. I can do that too Assorted formats
VoIP (Using a radio or connecting to a radio via the internet) Yup
Digital modes (Type not talk) Fantastic
Video modes, both slow and fast scan as well as static photos.
