Once the desired carrier is found:
7 From Controls, select Main.
8 Select Marker from the Choices field.
9 Use the Marker To field to select the desired carrier.
On the Test Set frequency and level are displayed as shown.
10 To demodulate the carrier:
a With the marker on the desired carrier, select Marker To to Center
Freq.
b From Controls, select Main.
c Select Marker from the Choices field.
d Decrease the Span to 1.5 MHz (or less).
e Adjust the Volume and Squelch controls to listen to the demodulat-
ed carrier.
