This report provides an in-depth discussion of the noise problems that are encountered in existing Defense Communications System frequency division multiplex baseband cable plants. The causes of these problems are cited test procedures to isolate and identify specific deficiencies are provided. Corrective techniques and their application for the reduction of noise within existing facilities are described. Often quoted but unsuccessful in practice methods for reducing RFI in TRIAX cable plants are discussed in terms of test results. System degrading measurement methods used to accomplish baseband sweeps and read baseband loading are disclosed. And finally, the economics of recovery of logged out communications channels is treated. Author
