What I don't have (easily and high quality) is a microphone, so you may not get specific bumpers for Capricon, but I can send you other little bits that I made for a different project. Hmm... do you want the bumpers I made for Dr. D at the 2004 Marscon? I don't know if he ever used them.

If I get a microphone... precisely what do you need in the way of Radio Capricon station ids? Suggested phrasing, please. I gather you're not an FCC station so there is no actual "legal" id, but I'd like to know what you need.
