The report covers modifications to the original breadboard Intervisibility System IVB. The redesign of the IVB produced a device capable of operating against low frequency background noise caused by cloud modulation of sunlight and atmospheric boil. The method used to accomplish the operational capability was narrowing the transmitted optical pulse allowing a wider passband and insertion of a high pass filter in the receiver. The results of field testing under sponsor supervision and recommendations for future intervisibility systems are also included in this report.
