If the Step Size is 25 kHz with the frequency set be-

changed to 100 kHz, the mismatch will cause the hex
code to display as two asterisks.

About Overlapping Frequency Bands

When two frequency bands overlap, it is possible to
select the same frequency at the upper end of one and
the lower end of the other. While the frequency will be
the same, the pilot tones will be different, as indicated
by the hex codes that appear.
In the following examples, the frequency is set to
494.500 MHz, but one is in band 470 and the other in
band 19. This is done intentionally to maintain compat-
ibility with receivers that tune across a single band. The
band number and hex code must match the receiver to
enable the correct pilot tone.

Selecting the Low Frequency Roll-off

Low frequency audio content may be desirable or
distracting, so the point at which the roll-off takes place
can be set to 35, 50, 70, 100, 120 and 150 Hz.
