1.2.1 Transceiver Model TiL-91-DE, P/N 901006-2
The basic model of each transceiver is required for the Low Power Base Stations. Option 1
indicates that the basic transceiver has a DC to DC convertor (Module A6) installed to
facilitate operation with the RF Amplifier Module. Refer to Section 3 for specific details on
the Transceiver unique to the systems indicated on the front cover of this document.
Transceiver Model Til-91-DE, Part Number 901006-2, is a microprocessor controlled, Low
Power VHF/AM transceiver operating over the entire band of 117.975 to 138.000 MHz in
25 kHz steps. The transceiver will store ten user selected frequency channels in addition to
the resident emergency channel of 121.500 MHz. Frequency Selection, Storage, Recall,
Channel Scan, Search, and Toggle modes are all selected by the 12 key keypad. Current
operating frequency is displayed on a backlit liquid crystal display (LCD).
Refer to above paragraph for details on new dual conversion receiver/transmitter A1
module.
1.2.2 Power Supply Modules - Models SPG-007, SPG-015, SPG-025
The Power Supply Modules provide the DC supply voltage to the Transceiver and Linear
Amplifier, and houses a battery charger which can provide charging and trickle charging to
external rechargeable batteries. Model SPG-007 is for use in the Low Power configurations,
Model SPG-015 is for use in the 15 Watt configurations, Model SPG-025 is for use in the
25 Watt configurations.
1.2.3 RF Amplifier Modules - Models PA-15 and PA-25
The RF Amplifier modules provide 15 Watt (Model PA-15) or 25 Watt (Model PA-25) power
output when the front panel switches are set to High. The RF Amplifiers are fed by the Low
Power RF output from the transceiver. An internal mounted RF relay bypasses the RF
Amplifier in receive and low power transmit modes.
1.2.4 Distribution Board
The Distribution Board provides all interconnection between the External DC connector, RF
Amplifier Module, Power Supply/Charger, Remote Control Board (optional), and Transceiver.
The optional Line Interface/Remote Control Boards are mounted on the Distribution Board.
The distribution board provides a 9 pin D connector and RJ-11 (2-wire audio available only)
telephone style jack for access to signals provided by the remote control board. The Line
Interface/Remote Control boards indicated in Table 1.1 are available for use with this
distribution board.
