Abstract : The report covers the development of a substitutive filter system for the RDZ/RDZ-1 receivers in which the major deficiencies have been improved to the extent permitted by existing space limitations and current availability of suitable components. As a result of the modifications described herein, the overall average protection against r-f energy introduced through the remote-line connections to the Model RDZ/RDZ-1 receiver has been increased to 112 decibels; i.e., an overall improvement of 59 decibels has been attained.
