I've been interested in radio communications since 2001 when my dad bought me the new-at-the-time PRO-93 scanner. I've just recently thought about getting into amateur radio and I have a few questions/concerns. Are there that many younger users out there (im 20)? If not, no big deal, as long as the older folk make me feel welcome on the air. Do new operators get looked down upon while on the air? Also, I've been reading several ham sites on the web and they mention how some repeaters are private as opposed to open. How do I know whether or not I may use it without getting chewed out on the air? Also, I do have a Motorola JT1000 HT, and am thinking about purchasing a mobile unit also if I decide to get my ticket.
