GENERAL DESCRIPTION
1.1 INTRODUCTION
VHF/AM Mobile Transceiver System 910200 (Item No. TMS-150), manufactured by Technisonic
Industries Limited, is a low power VHF/AM Transceiver, complete with Mounting Bracket, Power
Input Cable, Microphone and Antenna.
1.1.1 PURPOSE OF THE SYSTEM
(1) Intended Purpose and Use - The system is intended for installation in airport service
vehicles, such as cars, snowplows, and grass cutters, to allow ground control over such
vehicles while they are negotiating aircraft manouvering areas.
(2) Brief Description of System Units - VHF/AM Mobile Transceiver System 910200 consists
of the following items:
(a) Transceiver Model 91-DE, Part Number 901006-2, Series 1, is a low power VHF/AM
transceiver which operates in simplex and allows quick keypad access and LCD display
of the frequency range 117.975MHz to 138.000MHz with 25kHz channel spacing. The
transceiver operates from a 12 volts dc nominal vehicle power supply (negative ground
only). An optional extra cost dc to dc convertor P/N 863118-1 can be installed in the
transceiver to allow operation from an input supply from 10.8 to 30.0 Vdc. A general
view of the transceiver is given in Figure 1-1. The transceiver is normally located under
the dashboard of a vehicle using a mounting bracket and mounting hardware.
(b) Mounting Bracket, Part Number 913053-1, is a U-shaped aluminum alloy bracket
which, together with items of hardware included in Mounting Hardware Kit P/N 869024-
1, is used to mount the transceiver under the dashboard of a vehicle.
A view of the transceiver with mounting bracket is given in Figure 1-2.
(c) Power Input Cable Assembly, Part Number 863701, is a three-metre length of two-
core cable terminated at one end by a two-pin, female contacts, connector, which mates
with the two-pin, male contacts, connector located at the left-rear of the transceiver. The
unterminated end of the cable is connected to the 12Vdc vehicle power supply negative-
ground during installation.
A view of the cable assembly is given in Figure 1-3.
(d) Microphone Assembly, Part Number 961070-1, consists of a Microphone and a
mounting bracket, P/N RK6MB.
A general view of the microphone assembly is given in Figure 1-4.
The microphone is a rugged hand-held microphone housed in a high impact plastic case
which includes a rear case hang-up button for storage on the mounting bracket. The
dynamic microphone is a noise cancelling type with a pre-amplifier, press-to-talk switch, and
a retractable three-cord cable terminated by a three-pin male contacts, connector which
mates with the MIC/PTT connector located on the front panel of the transceiver.
The microphone dc supply for the microphone is supplied by the transceiver. The
mounting bracket, provided with the microphone, should be mounted in a convenient
location near the transceiver. A small screwdriver which can be used for releasing the
modular plug located in the microphone head is supplied with the microphone.
A replacement plug-in microphone cord, P/N 963299-1is available for this microphone. This
cord is supplied with a modular microphone plug on one end and a three-pin DIN connector
on the other to mate with the Model 90-6R Transceiver.
