INSTALLATION AND HARDWARE SUPPLEMENT
8.1 Purpose
This supplement provides installation and maintenance information associated with the RT-9000C ISB
Transceiver. ISB stands for Independent Sideband. ISB capability in the RT-9000C is implemented through
the use completely re-designed IF and Audio Assemblies functioning together as a two board set. The re-
designed assemblies rely on Digital Signal Processing (DSP) techniques to generally improve existing
performance and, at the same time, implement ISB capability.
This supplement provides specific installation, maintenance, and repair information concerning the RT-9000C
Transceiver model. Additional updated information is also provided for subject areas covered in the original
manual to which this supplement is attached. Since the RT-9000C is based on earlier RT-9000A and RT-
9000B models, this updated information also applies to those models.
While unrelated to the RT-9000C, a replacement Frequency Synthesizer was introduced approximately six
years ago. The same assembly is used by the RT-9000A and RT-9000B Transceivers, T-9400
Transmitter/Exciter, and R-9200 Receiver models. This supplement provides maintenance information about
this synthesizer replacement assembly.
