  1 I recently purchased a Federal Jr. crystal set at a radio meet. There are five binding posts on the top--a group of two and a group of three. Can someone tell me which posts are for headphones--the two?-- and which are for antenna and ground? Thank you.

  2 The group of 2 are for headphones. Looking at the set from "ANTENNAE"  site  the group of 2 to the right are for headphones. In the group of 3 posts the 2 from above are for antennae and the lower one is earth.
View the pictures here in RMORG. Type in Federal jr as model name.

The very early model was made of brass. Another hint for early models is a label at one of the small sides, showing all the  patents, applied to this unit.
