BendixKing KAC 952 coupler 064-1017-01

064-1017-01 is the exact Part Number for this BendixKing KAC 952 HF power amplifier and antenna coupler. The unit is a remote-mounted component of compatible KHF 950 high-frequency communication systems. It is not a cockpit control head or a complete radio by itself. Its role is to amplify the transmitted HF signal and automatically tune the connected antenna system for efficient operation across the selected frequency.

The authentic identification photograph confirms model KAC 952 and the complete 064-1017-01 suffix. The plate also describes the unit as an HF power amplifier/antenna coupler. Because several KAC 952 assemblies share a similar enclosure, the full Part Number must be checked rather than relying only on the model name or exterior shape.

HF communication function in the KHF 950 system

In a typical KHF 950 installation, the crew selects a frequency or stored channel through a compatible KCU 951 control unit. A KTR 953 receiver/exciter generates and processes the radio-frequency signal, while the KAC 952 performs the power-amplifier and antenna-matching functions required for transmission. The coupler adjusts the antenna circuit so that the transmitter can deliver energy to the installed HF antenna under the approved aircraft configuration.

A simplified functional path is KCU 951 control selection → KTR 953 receiver/exciter → KAC 952 power amplifier and antenna coupler → approved aircraft HF antenna. During reception, system routing and control remain dependent on the complete installation. These associated components are part of the same communication architecture but are not interchangeable with the KAC 952 and are not included unless a quotation states otherwise.

HF performance depends on the aircraft antenna, bonding, ground plane, feed line, control wiring and the condition of all connected equipment. Installing a serviceable coupler cannot compensate for an incorrect antenna installation, damaged coaxial cable, poor bonding or a fault in the receiver/exciter. Troubleshooting should therefore follow the aircraft and KHF 950 maintenance procedures.

Electrical data and exact connector identification

The exact identification plate specifies 28 VDC operation and lists a transmitter current of 15 A and receiver current of 0.1 A. The unit weight shown on the plate is 14.0 lb, equivalent to approximately 6.4 kg. Qualification markings include TSO C31c and C32c together with DO-163 and an environmental category code. These values are taken from the photographed exact-suffix unit and should be checked against the applicable installation data before release to service.

Visible interface labels identify transmitter input J9521, transmitter output J9522, tuner input J9523 and control connector J9524. A separate antenna connection is provided on the opposite end of the enclosure. These designations help distinguish the RF, tuner and control paths during installation, but connector pin assignments, cable specifications and test limits must be taken from approved wiring and maintenance documentation.

The complete suffix remains important. KAC 952 versions 064-1017-00, 064-1017-01 and 064-1017-02 appear in maintenance literature, yet this product is offered specifically as 064-1017-01. No interchangeability with another suffix is claimed without verification of the aircraft equipment list, modification status, connectors, wiring and system approval.

Installation, inspection and maintenance checks

The KAC 952 is installed as a remote avionics unit using its enclosure rails and aircraft-specific mounting provisions. Installation work must confirm rack security, electrical bonding, cooling, circuit protection, RF cable condition, antenna connection and control wiring. The aircraft maintenance manual defines the approved location and any clearance, ventilation or lightning-protection requirements.

Receiving inspection should verify Part Number 064-1017-01, serial number, modification marks, identification plate, enclosure seams, mounting feet, RF fittings, protective caps, J9521 through J9524 interfaces and the condition of the antenna connection. The release document and overhaul status must correspond to the offered serialised unit. The authentic photographs are used to identify the product type and suffix; they do not replace the release paperwork supplied with the quoted stock position.

After installation, an approved technician should complete the prescribed power, control, tune and transmit checks using suitable test equipment and a safe RF test arrangement. The unit must not be operated into an unapproved load. Any functional test should also confirm communication with the control head and receiver/exciter, correct tuning behaviour and the absence of connector, bonding or overcurrent faults.

Overhauled supply and ordering information

This 064-1017-01 KAC 952 is offered in Overhauled condition from partner stock with a six-month warranty. Overhauled describes the stated supply condition, while the exact shop, tag date, serial number, modification status and release documentation remain subject to the quotation for the available unit. The photographs should not be interpreted as a promise of a particular pictured serial number.

For an inquiry, specify Part Number 064-1017-01, model KAC 952, aircraft model and serial number, installed KHF 950 configuration, required release document, modification requirements, connector or mounting needs and quantity. Related HF controls, receiver/exciters and other avionics can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Related products may operate in the same system but are not represented as substitutes.
