I recently co-instructed a technician class (one of four or five sessions) and this is a few resources for the students as well as any new ham. I am going to try to keep this up-to-date.
First off, I think all new hams should read this article by Chris Seright KE5ZRT. He does a great job of what you should do now that you have a license.
Second off, the stuff below is a laundry-list of clubs, emergency groups, nets, and other items of interest to new hams. It is specific to Clermont County and the Cincinnati region. This is not all-inclusive!
