The VoA museum near the WLW Antenna does give tours on the weekend of the VoA transmitter (Voices of America) that was located near the WLW Transmitter -- sadly, it's only open on the weekends, but, it's still a really fun tour that talks about the shortwave transmission history of VoA. During Hamfest (usually held in Xenia now that Hara Arena is gone), you can usually get a tour of the WLW transmitter site.
