2. If more than one hot spot is found, mark them and return to the
transmitter and turn it off. Lift the black lead from the ground
stake and connect it to the common wire. Turn the transmitter
on, set the selector knob to the highest reading, and return to
the first hot spot with the receiver. Touch the tip of the receiver
antenna to the ground in the center of the first hot spot and
set the sensitivity knob to read near mid-scale. Now go to the
second spot and without touching the sensitivity knob, check the
strength of the signal at each hot spot and determine which, out
of all of them, is the strongest signal. This is the value for the
station wire you are connected to.
