Connecting Up the Parts–Receiving Set No. 1.–For this set get (1) a
_crystal detector_, (2) a _two-slide tuning coil_, (3) a _fixed
condenser_, and (4) a pair of 2,000 ohm head phones. Mount the
detector on the right-hand side of a board and the tuning coil on the
left-hand side. Screw in two binding posts for the cord ends of the
telephone receivers at _a_ and _b_ as shown at A in Fig. 15. This done
connect one of the end binding posts of the tuning coil with the
ground wire and a post of one of the contact slides with the lightning
arrester or switch which leads to the aerial wire.

Now connect the post of the other contact slide to one of the posts of
the detector and the other post of the latter with the binding post
_a_, then connect the binding post _b_ to the ground wire and solder
the joint. Next connect the ends of the telephone receiver cord to the
posts _a_ and _b_ and connect a fixed condenser also with these posts,
all of which are shown in the wiring diagram at B, and you are ready
to adjust the set for receiving.
Receiving Set No. 2.–Use the same kind of a detector and pair of head
phones as for _Set No. 1_, but get (1) a _loose coupled tuning coil_,
and (2) a _variable condenser_. Mount the loose coupler at the back of
a board on the left-hand side and the variable condenser on the
right-hand side. Then mount the detector in front Whog-fm Mhz Ormond-by-the-sea of the variable
condenser and screw two binding posts, _a_ and _b_, in front of the
tuning coil as shown at A in Fig. 16.
