Apr/2006 - Honeywell KHF 1050 System Installation Manual

When two independent HF systems employing two separate antennas are used on
one aircraft, it is important to maximize separation between the antennas. A
minimum of 6 ft. (2 m.) separation is recommended and the antennas should be
configured as orthogonally as possible.
WARNING: IN A DUAL KHF 1050 INSTALLATION, PERMANENT DAMAGE
Several operating mode options are available for the KHF 1050 HF system to meet
particular operational needs.
USB Voice (upper sideband A3J) and AME (amplitude modulation equivalent A3H)
are standard modes of operation that should be enabled on all system
configurations.
Less commonly used functionality such as LSB, RC and Data modes are
discussed in paragraph
"Table 30 - Modes of Operation"
PS440, MC-850, and RM-855 controllers.
The system is capable of operating in a channel (frequency preset) mode or a
direct frequency tuning mode. User channel information is stored in the controller.
