A. INTRODUCTION
The UTX1KW-A transmitter was designed to meet or exceed all FCC applicable specifi cations for TV
Broadcast Equipment. Special attention was given to the selection of sub-assemblies and components to
achieve maximum reliability and minimum down time. The construction of the UTX1KW-A is BASIC
and MODULAR with most components fi eld replaceable. Special emphasis was placed on KEEPING IT
SIMPLE and returning to more traditional transmitter layouts and instrumentation.
This transmitter was designed for Analog (NTSC) transmission with provisions and options available to
convert to Digital Service when necessary.
Refer to the UTX1KW-A block diagram — fi gure 1 (page 9) — for an overview of the transmitter
architecture. This will give the technician basic information needed to understand the operations of the
transmitter and the function of each subassembly.
