1. INTRODUCTION. The PANADAPTOR is a highly versatile piece of equipment. Its usefulness grows continuously as ones experience with it increases. It will make any good Receiver better. But what the PANADAPTOR does and how it does it, is of course, determined by the Receiver and the operator. The PANADAPTOR needs intelligent handling and careful interpretation of results. The purpose of this handbook is to familiarize the operator with the operation, application and interpretation of Panoramic Reception, with PANADAPTOR Model PCA-2, Type T-200. Please read the handbook carefully. Complete Installation and Maintenance data for PANADAPTOR Model PCA-2, Type T-200, are provided in individual sections. 2. GENERAL Through its many applications, the PANADAPTOR provides information and operating technique not obtainable in any other way. Upon connecting the PANADAPTOR to any standard communications receiver, both visible and audible reception of all signals receivable within the tuning range of the Receiver are possible. The aural Receiver used with Model PCA-2 must be a superheterodyne having an I.F. between 450KC and 470KC. It is preferable that this Receiver have at least one R.F. stage for adequate image rejection. Note The PANADAPTOR is factory adjusted for a mean input frequency of 455 KC. For best results the mean input frequency of the PANADAPTOR should match the Receiver I.F. If they do not match, the R.F. Bandpass Amplifier of the PANADAPTOR must be realigned according to Alignment Procedure Section V. Six types of operation are available as follows: a. VISIBLE PANORAMIC. Signals (within a band extending up to 100KC above and below the frequency to which the companion Receiver is tuned) appear as individual vertical “pips”, in order of frequency, at a definite location along the calibrated horizontal axis of the Panoramic screen. As the Receiver is tuned, the “pips” move across the screen and “walk-off” at one side while new pips enter on the opposite side. For any setting of the Receiver tuning dial, the “pip” appearing at the center or zero mark of the screen represents the signal to which the Receiver is tuned.
