Yes, Ham radio exists here in central KY. It actually exists worldwide. First, for the uninitiated, just because someone is talking into a microphone does not make it Ham radio. What many truckers use is what used to be CB radio and is in no way connected to Ham radio.

Ham radio not only uses microphones to communicate but also uses Morse code keys and computers, as well as TVs and other devices. The hobby is so diverse that just about any technical interest is included from just someone talking to another Ham to bouncing signals off of the moon and everything in between.

Locally, we have a club and meet once a month just outside of Columbia. Here is our web page for those that may have more interest: http://wa4uxj.com/
Many of us also belong to our national organization, the American Radio Relay League. Here is that web page: http://www.arrl.org/
The above should get you off to a start and maybe another Ham will add more comments.
