Ham radio is an interesting hobby.
ARRLWeb: ARRL Home Page is a great place to start for information. Most hams call their license their ticket. I'm not sure where that came from. There is basically nowhere that isn't reachable by radio at some point during a 24 hour cycle. Where one can talk depends on the level of license. In the U.S. we have 3 levels, technician, general and extra. The tech license is the most basic. It allows full privileges on vhf/uhf and very limited privileges on hf. The hf bands are the ones that reach worldwide. A tech is allowed one very small segment of one hf band for voice and small segments of 3 other hf bands for CW (Morse code) only. On CW one could work worldwide easily with just a tech license. The general license allows voice and CW on all the hf bands. The extra allows more frequencies than the general.
Equipment can be bought used to set up an hf station for just a few hundred dollars. Equipment for v/u can be had for just a couple hundred dollars. Lots of guys like to build their own antennas and some even build their own radios. That's far more skilled than I am. I have 10 thumbs when it comes to that stuff. There is even an American company in the radio business still. They supply much of the equipment for the troops as well as ham stuff.

I'll be glad to try to answer any questions but I'm nowhere near an Elmer yet. Elmer is the ham term for a mentor so being an Elmer is a good thing... well, unless maybe your last name is Fudd and you are foiled all the time. hi hi (hi hi is the ham version of ha ha).
