Operation - Honeywell KHF 1050 System Installation Manual

Preliminary - Subject to Change Without Notice
WARNING:
Several operating mode options are available for the KHF 1050
HF system to meet particular operational needs.
USB (upper sideband A3J) AME (amplitude modulation equivalent
A3H) are standard modes of operation permitted on all system
configurations.
LSB (lower sideband A3J) operation is not permitted for
stations operating under Part 87 FCC (USA) regulations. LSB
may be enabled for use in regions or applications where its
use is authorized.
A seldom used mode A3A (USB reduced carrier) if available for
use in locations that may utilize the mode.
Table 23, Modes of Operation, lists the modes of operation
applicable to the PS440, MCDU, and RM-855 controllers.
The system is capable of operating in a channel (frequency
preset) mode or a direct frequency mode. A microcomputer
within the system provides the following functions:
• controls the non-volatile storage of frequency, mode and
channel data
• controls a multiplexed eight-digit frequency display
• provides synthesizer serial data tuning information
• provides tune and transmit mode control logic
• provides band switching information
• preset antenna tune
• built-in test with fault display
Dashed lines and shaded boxes in the block diagram, Figure 5,
indicate for future use.
