SECTION 1 - GENERAL DESCRIPTION
1.1 INTRODUCTION
This publication provides general information on the VHF/AM Single Channel Receiver Model
TiL-92-SC, Part No. 931040-1, manufactured by Technisonic Industries Limited. This unit is also
referred to by Item No. TSR-4100.
The Model TiL-92-SC, Receiver is a single channel, fixed frequency receiver operating over the
frequency range of 117.975 MHz to 138.000 MHz. This unit is intended for base station operation
in an air traffic environment. The unit can operate from AC power or external DC power in local
and remote operating modes.
1.2 DESCRIPTION
The 92-SC rack mounted receiver configuration is based on the Model 90-6R pre-programmable
transceiver module. This module, as modified for receiver only capability utilizes similar circuitry
as the 90-6R with appropriate deletion of transmitter functions. In addition to this modified
transceiver module, the receiver consists of a Power Supply Module, Mother Board, and Remote
Audio Board.
An optional RF Crystal Filter which provides higher receiver selectivity is available. These filters
can be ordered to provide either an additional 20dB (4 dB loss sensitivity) or 40dB (7 dB loss) of
selectivity.
An Optional Module A6 which is a DC to DC power supply is available in the 90-6R Receiver unit.
This optional power supply will allow the 92-SC Receiver to operate with a 24 Vdc input as
opposed to the standard 12 Vdc input. When the units are operating in the AC mode and external
batteries are connected a DC charging circuit will automatically trickle charge the batteries and
the unit will switch to DC operation should the AC mains fail.
