There are 5 kinds of ceramic
filter (CF 1) available with this
unit and they are given color indication as tabulated below to
differentiate the central frequency from one to another among
them,
When

of 10.7 MHz
are used, note that a marker
(10.7 MHz) of FM sweep generator, if used, will be deviated —
therefore, adjust the generator by putting off the marker.
