INTRODUCTION
General Description
The Telex Model’s TR-200 and TR-200P Belt-pack Transceivers, are designed with one transmit and one receive channel and will operate on selected frequencies within the 150 to 216 MHz band.
The TR-200 Transceiver operates in the continuous transmit mode with the audio, or talk, activated by a switch. As many as four TR-200 belt-pack transceivers can operate in a fully duplex network with one Telex Model BTR-200 or BTR-200 II Base Station.
The TR-200P Transceiver operates in the Push-to-Transmit mode (the transmit and talk function are activated together). Any number of TR-200P transceivers can be used in a half-duplex network with one BTR-200 or BTR-200 II Base Station. Op- erate only one transmitter at a time. Attempting to use two transmitters simulta- neously on the same channel will cause interference.
Both the TR-200 and TR-200P can be configured to operate with another TR-200 or TR-200P.
The receiver portion of the TR-200 and TR-200P consists of a crystal controlled dual conversion superheterodyne design.
The transmitter portion of the TR-200 and TR-200P consists of a crystal controlled multiplier/amplifier design.
