You need to know where the wire leads need to be sanded to make connections.
Route the coil wire, as shown in the following diagram, by loosening the Phillips
screws mounting the two Fahnstock clips labeled ANT and DET1 (as shown):
3.5”
2.5”
! Measure and mark the coil wire lead at the left-hand side of the crystal set at
3.5 inches. The measurement is taken from the point where the wire exits
the form.
! Remove about 1” of insulation at the 3.5” mark.
! Form the wire so the area stripped of insulation forms a through connection.
! Loosen the Phillips head screw for the ANT Fahnstock clip.
! Route the through-connection loop so it passes between the ANT Fahnstock
clip and breadboard.
! Tighten the ANT clip mounting screw so it is snug.
! Measure and mark the wire lead emerging from the antenna clip at 2.5”.
! At the 2.5” point, remove 1” of wire insulation, and form a second through-
connection half loop.
! Loosen the Phillips screw mounting the DET1 Fahnstock clip.
! Route the second through connection so it passes under the DET1
Fahnstock, loops around the screw shank, and exits as shown in the
drawings.
! Tighten the Phillips screw for the DET1 clip so it is snug.
! Several inches of wire should remain from the DET1 clip connection, this
will be used later. Do not cut the wire until told to do so!
In the next few steps you will be working with the right-hand coil wire. Refer to
