tween even 100 kHz steps and the Step Size is then
changed to 100 kHz, the mismatch will cause the hex

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
It is possible that the low frequency roll-off point could
affect the gain setting, so it’s generally good practice to
make this adjustment before adjusting the input gain.
The point at which the roll-off takes place can be set to:
• LF 35 35 Hz • LF 100 100 Hz
• LF 50 50 Hz • LF 120 120 Hz
• LF 70 70 Hz • LF 150 150 Hz
The roll-off is often adjusted by ear while monitoring the
audio.
