Telex TT-16, TR-16 manual Introduction, What Is The Telex Wireless Ifb System?

INTRODUCTION

WHAT IS THE TELEX WIRELESS IFB SYSTEM?

Transmitter: The transmitter generates and ampli- fies a RF (Radio Frequency) carrier signal, modu- lates this carrier with the microphone signal, and radiates the modulated RF carrier.

Receiver: The FM VHF receiver is tuned to the fre- quency of the transmitter. The receiver picks up the radiated RF signal from the transmitter through the antenna and converts the RF signal into audio volt- ages for use with an earphone, headphone, button receiver, neckloop, etc. The receiver frequency must be matched to the transmitter frequency.

WHAT FREQUENCY BAND DOES THE TELEX SYSTEM OPERATE IN?

The Telex Systems feature a synthesized transmitter and a synthesized receiver operating in the VHF Band between 64-68 MHz. See Table 1 for standard frequencies available.

Each transmitter channel can be utilized by any number of receivers in any given area. Up to five si- multaneous systems can be used in a given area.
