The joke in the programming world, of which I have been a part for many years is the first baby program is always concerned with outputting a simple “Hello World” to the screen.
So in Ham lingo, talking to the world, instead of your local area is called DX-ing.
In the old days, you need a HF (High Frequency) transceiver to make world wide contacts, but these days, with the advent of digital and VOIP modes, you can literally use your phone (via Echolink) to talk to hams in other countries.
There are other ways too, but with Echolink you can get set up in minutes and be looking for your first DX the same day you get your license.
How cool is that?
