Abstract : Part I pertains to the expansion of the equipment and program versatility and is of most interest to personnel directly involved in the operation of Granger sounders. The subject matter is discussed in general terms and illustrated with block diagrams which show specific points of connection to the Granger system. Part II describes several data recording devices used at College which are of general interest since they are, in whole or in part, applicable to many types of ionospheric recording equipment. Among the devices described are a variable speed recording camera system, two types of video processors, and an HF transponder unit. All circuits are described in detail with complete block and schematic diagrams, and their effect on the recorded data is considered in detail. As an aid to the scaling and evaluation of the College data, a comprehensive table is included which lists the data recording system and equipment sensitivities for the period October 1963 through March 1965. Part III describes another data recording system which has allowed the addition of amplitude information to the standard ionogram record. This system has been used with the vertical incidence sounder at College and provides supplementary information for the analysis of backscatter and forward oblique records. (Author)
