Survey of the 603 tactical communications squadron (TCS) on-site grounding system located at Sembach AFB, Germany by representatives of the 1842 EEG and the 1839 electronics installation group in order to investigate and recommend corrective action to eliminate the source of 400 Hertz 'hum' on communication circuits between the 603 TCS and 2134 communications squadron technical control facility.

Satellite Communications Set AN/WSC-3, Antenna Group OE-82A/WSC-1(V), and associated interface equipments installed aboard the USS AINSWORTH (DE 1090) were checked for proper operation for subsequent operational evaluation. Testing included a surface examination and verification of terminal performance, antenna performance, and proper baseband interface. Two AN/WSC-3 module failures and two OE-82A/WSC-1(V) equipment failures occurred during the shipboard validation tests and were satisfactorily resolved. Two required AN/WSC-3 modifications were installed with satisfactory ...
One major purpose of this project is to study mathematical methods of modeling the actual tranmission data so that several parameters of a model can capture the essence of the statistical performance of data transmission on a real channel. This model when verified to be an accurate representation could then be used compactly in the computer to simulate the behavior of the real channel or to evaluate the performance of ...
