About Overlapping Frequency Bands

When two frequency bands overlap, it is possible to select the same frequen-

cy 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

compatibility 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.
