INTRODUCTION
KHF 950/990 COMMUNICATIONS TRANSCEIVER
High frequency (HF) communications made easy, that’s what the
King KHF 950/990 HF SSB Transceiver is all about.
The KHF 950/990 is a compact, lightweight system to provide an
extensive range of operator benefits. It is designed with international
flight operations in mind to provide superior long range communica-
tions.
A basic KHF 950/990 system consists of either three or four units
including your choice of either a miniature Gold Crown III style (KFS
594) or two different Dzus rail-mounted control display units (KCU
951 & KCU 1051). Additional hardware is available to allow the KHF
950 system to tune most shunt and notch antennas used on some
corporate jet aircraft. It can also be installed in a dual configuration
sharing the same HF antenna, and yet provide a dual receive capa-
bility which many corporate users find highly desirable. The KCU
1051 will provide Automatic Link Establishment (ALE). This allows
automatic selection of the optimum frequency and linking to another
ALE system.
Microprocessor control of vital frequency selection functions provides
an unprecedented number of programmable channels, greater ease
of changing these channels on the ground or in the air, and direct
access to a full 280,000 operating frequencies from 2.0 to 29.9999
MHz. The control heads provide extreme ease in fully utilizing the
semi-duplex channels of the maritime radiotelephone (public corre-
spondence) network.
There are three types of control heads available. The KCU 1051
control display unit provides Automatic Link Establishment (ALE)
capability. The KCU 1051 is a Dzus rail-mounted unit with 200 pro-
grammable channels, 100 for manual channels and 100 for ALE
channels, also all 245 ITU channels used by the maritime radiotele-
phone network are preprogrammed into non-volatile memory. No
additional programming of ITU channels is ever required. With the
KCU 951 Dzus rail-mounted control display unit, 99 pilot programma-
ble channels are available. With the KFS 594 miniature control dis-
play unit and its associated remote adapter unit, 19 pilot programma-
ble channels are available and, in addition, all 245 ITU channels used
by the maritime radiotelephone network are preprogrammed into
nonvolatile memory. When the KFS 594 Control Display Unit is used,
no additional programming of ITU maritime radiotelephone network
channels is ever required.
