The Longmont Amateur Radio Club is offering an Amateur Radio Technician class next month (HAM radio). The exam is at the end of the month, which is technically not part of the class. I suspect you could study on your own and register for the test if desired. Details are in the link below.

I plan on attending the class to learn some of the basics.
Cheers,
