Chapter 8 Schematics, Board Overlays, and Parts Lists
This chapter contains the schematics, board overlays, and parts lists 
for the XTS 5000 radio. Use them in conjunction with the theory of 
operation and the troubleshooting procedures, charts, and waveforms 
to isolate a problem to the component level.
When schematics are viewed on line or as a PDF file, colors can be 
seen that denote power and signal paths. The red color denotes 
voltage paths, blue denotes the receive path, and green denotes the...
