Echolink

It is a while since I have tried Echolink. With Echolink on your phone or PC, you can access repeaters on the other side of the planet, often used by locals to talk to others on VHF or UHF handhelds. You can even buy network radios that use the internet as the main bearer. 

I have an Android handheld with PTT that looks and feels just like a VHF handheld. I have to admit it is not used often as I prefer experimenting with "real" radio! 

If you cannot have big antennas or amateur radio in the conventional way, this may be a way to keep in touch.
