I have an old Radio Shack? Science Fair Radio kit model 28-222 -
without instructions..

I need to know where to connect the entenna coil wires, the
speaker/headphone jack, and the battery. I have found points with W,
R, and G that look like the place to connect the red, green, and white
coil wires, but cannot figure out where the black goes. The speaker
connections and battery connections are a complete mystery

Anyone have the instructions floating around or one you could send
pictures of? It's been sitting here uncompleted for a LONG time.

Clare-

I found a discussion about your radio kit at
http://www.antiqueradios.com/forums/viewtopic.php?f=4&t=188702nk. It
includes links for data that has apparently been removed due to
copyright problems.

If you can make contact with participants in that discussion, they may
be able to answer your questions.

Another discussion at
http://www.antiqueradios.com/forums/viewtopic.php?f=4&t=196521
suggested that the Radio Shack version was very similar to a Graymark
536 AM Radio kit. Perhaps someone in that discussion can answer your
questions.
