Ham (amateur) radio has a strong tradition of mentoring, or "Elmer-ing" in ham-speak. If enough hams and ham-wannabes can be gathered, how about having a mini-camp to talk about ham radio topics of interest to us and probably others? There could be discussions on any and all aspects of ham radio, demonstrations, and maybe demonstrate a bit of radio to other BarCampers.
Eugene Mah is a medical physicist and a relatively newly licensed ham radio person (call sign KK4JRP). He currently holds a General amateur radio license and is hoping to have his Amateur Extra license by the time BarcampCHS 4 rolls around.
