Page 3: General Technical Description
Hand-held Transmitter GENERAL TECHNICAL DESCRIPTION The T195 / UT195 transmitter is comprised of a number of functional sub-systems as shown in the block diagram below. The T195 and UT195 utilize 75kHz deviation for compatibility with the 195 series receivers. The transmitter circuits are all regulated to allow full output power from the beginning (9 Volts) to the end (7 Volts) of battery life. -

The 195 system utilizes a separate ultrasonic tone modulation of the basic carrier to operate the receiver squelch. A 32kHz tone is injected into the audio signal after the microphone preamp, just after the compandor. The supersonic pilot tone is filtered out of the audio signal immediately after the detector in the receiver so that it does not influence the compandor or various gain stages. - Page 5 Hand-held Transmitter EXTERNAL SWITCHES BYPASS This concealed slide switch defeats the external switches on the bottom panel for applications where it is best that the user not be able to operate the power and mute switches.
