Output channels

The vestigial sideband modulator BLV permits using adjacent channels.
RF output channels that are adjacent to each other or adjacent to the earth
TV channels from legal re-emitters (both lower and higher channels) can
be programmed.
If the installation includes external units that use double sideband
modulators, the channels immediately below the ones used by those units
must be free.
3.5 Channels from other units
PA amplifiers include a EXT input extension for channels from other units.
The channels added so join the output channels of the MS unit.
