In the course of the research on the program schedule there are a lot of programs that remain a bit of a mystery. Sometimes it seems obvious what they might be, but identification from a variety of sources helps for researcher verification. If you remember some of the following programs please write to us at the contact address or e-mail to firstname.lastname@example.org (or telephone in your information). Listener help is always appreciated. The list is at present being compiled and not ready yet.
