KHF 950/990
SYSTEM DESCRIPTION.
The KHF 950/990 is a solid-state HF single sideband transceiver sys-
tem. The KHF 950 system can be controlled by either a KCU 1051
Dzus rail-mounted control display unit, a KCU 951 Dzus rail-mounted
control display unit, or a miniature KFS 594 Gold Crown III style con-
trol display unit. The KFS 594 requires an extra remote unit (KA 594)
which contains electronics associated with this miniature panel-
mounted control display unit. All the control units work in conjunction
with a KAC 952 power amplifier/antenna coupler and a KTR 953
receiver/exciter.
The KHF 990 system can be controlled by either a KCU 1051 or the
KFS 594 Control Display Unit. These control units work with the KAC
992 Antenna Coupler and a KTR 993 receiver/transmitter.
KCU 1051 CONTROL DISPLAY UNIT
The KCU 1051 Control Display Unit (Figure 2-1) adapts the existing
KHF 950 and KHF 990 High Frequency Radio systems for use with
Automatic Link Establishment, providing the pilot’s display and con-
trol interface. Frequency, channel, mode, ALE address, audio gain,
and squelch level selections are entered via its controls. Fault moni-
toring and fault annunciation are also provided by the KCU 1051.
The KCU 1051 provides the pilot access to 100 manual channels,
100 ALE channels, and 245 ITU channels to interface with maritime
radiotelephone networks. The KCU 1051 uses a liquid crystal display
to show frequency, channel, and mode of operation. The manual
and ALE channels can be easily programmed by the pilot on the
ground or in the air, and the nonvolatile memory stores this informa-
tion even when the system is turned off.
