SECTION 1 – GENERAL DESCRIPTION
1.1 INTRODUCTION
The following document covers both the installation and operation of the AMS-6000 Audio
Mode Selector.
1.2
PURPOSE OF EQUIPMENT
The AMS-6000 Audio Mode Selector is designed to provide enhancements to a TDFM-
600/6000 series transceiver installation.
1.3 DESCRIPTION
The AMS-6000 is an audio mode selector box that is designed to work in conjunction with
the Technisonic TDFM-600/6000 series airborne FM transceivers. The AMS-6000 will
combine the audio and key lines from up to three separate RF Bands in a TDFM-6000 and
permit the TDFM-6000 to operate as a single transceiver from one position on an audio
controller. The TDFM-6000 which operates on three RF bands normally requires three
positions on an audio controller and the TDFM-600 normally requires two positions.
When the AMS-6000 is used in the “combined radio mode”, the receive signal from each of
the three RF bands is annunciated by a receive LED and the transmit selection/indication
functions for each band are also supported via transmit buttons with LED’s for each band.
Missions that require simultaneous operation of all three RF bands in a TDFM-6000 will also
benefit from the use of an AMS-6000. If the AMS-6000 is used in the “separate radio
mode”, all three RF bands of the TDFM-6000 are connected to three different audio
controller positions. Receive indication on any of the three bands is annunciated on the
AMS-6000. Transmit selection would be made via the audio controller in the separate radio
mode. Given that the TDFM-6000 will only display information about a single band at once,
the AMS-6000 will provide receive indication for all three bands and allow rapid response to
RF traffic over multiple bands along with simulcast and cross band repeat capability also
supported. The benefits of an AMS-6000 in the “separate radio mode” would be most
pronounced when it is utilized with a three band TDFM-6000 series transceiver.
The AMS-6000 transmit selection keys can also be used to simulcast the transmit function
on two or three of the RF bands or to invoke a cross band repeat function between any or
all of the 3 bands. The simulcast and cross band repeat functions are supported in either the
combined or separate radio modes. The AMS-6000 also provided a front panel connector to
allow PC memory frequency and encryption key programming for each of the bands in the
TDFM-6000 that it is installed with. This will pre-empt the requirement to wire a PC
programming connector from the TDFM-6000/600 to a bulkhead connector in the airframe.
1.4 MODEL
VARIATION
There is only one version of the Model AMS-6000, P/N 031220-1. All units support both 5
and 28 volt back lighting and all are NVG compatible.
