VHF frequency selection and KTR 908 control

The KFS 598A lets the crew prepare a standby frequency and transfer it into the active selection without directly tuning the remote transceiver chassis. The large channel control changes the selected digits, while the SBY transfer switch exchanges active and standby values. The VOL / OFF control provides audio-level and power selection, and its push-to-test function supports the approved system test arrangement.

Exact product information for 071-1282-86 identifies frequency control up to 151.975 MHz. In a typical signal path, KFS 598A commands pass to the KTR 908 remote VHF transceiver; the radio then routes receive audio to the aircraft audio system and transmitter output through approved coaxial cable to the VHF antenna. Installation approval must cover both the controller suffix and the connected transceiver configuration.

115 V NVG configuration

Repair-capability and exact-part listings identify 071-1282-86 as a black KFS 598A communication controller with 115 V lighting and an NVG-compatible display configuration. The red 115 V lighting caution label is visible on the authentic photographed unit. This lighting value applies to the illumination circuit and must not be described as the operating supply for the remote KTR 908 transceiver.

NVG compatibility is configuration-specific. A visually similar 28 V or non-NVG KFS 598A is not an automatic substitute for the -86 version. Before installation, verify the faceplate colour, lighting supply, display layer, software and modification status, front controls, rear connectors and aircraft dimming circuit. The exact lighting connection and protection requirements must come from approved wiring data.

Identification, weight and installation checks

The original side plate identifies KFS 598A, P/N 071-1282-86 and a weight of 1.4 lb, approximately 0.6 kg. The photographed unit also carries software-control references CTL 125-0110-01 and INT 125-0036-00. These markings describe the illustrated unit and should be checked during receiving inspection without assuming that every unit of the same Part Number carries the identical serial or repair label.

The KFS 598A is a panel-mounted control head connected to remote avionics through aircraft wiring and rear multi-pin connectors. Bench testing should confirm both display lines, digit selection, active/standby transfer, volume, OFF and test functions, annunciation, illumination and serial control communication. Exact dimensions, connector pin assignments and installation cut-out data must be taken from the applicable KFS 598A / KTR 908 documentation.

Overhauled supply and ordering information

This 071-1282-86 KFS 598A is offered in Overhauled condition from partner stock with a six-month warranty. The studio main image shows the correct front-panel layout, and the authentic gallery image preserves the original 071-1282-86 identification plate, 115 V warning, software labels and housing details. The quotation will identify the allocated serial number and available release documentation.

For an inquiry, specify Part Number 071-1282-86, model KFS 598A, connected KTR 908 configuration, 115 V NVG requirement, required documentation and quantity. Related communication controllers and transceivers can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. A related KTR 908 is part of the same functional chain but is not interchangeable with the KFS 598A control head.
