The name says it on the tin. I tend to lurk for hte most part but I have been meaning to ask this. How can one find out historical or past frequencies? If I was writing a story, book or just plain curiousity, if I wanted to know what frequencies Greater Pittsburgh Airport used in 1978 or what frequencies Pittsburgh police (or anyone) used in 1965, where can one find that info if it can be done?
