The report contains a complete description of a Portable FM Seismic Transmitting and Receiving System capable of unattended operation. It is specifically designed to broaden the capabilities of the portable seismic system developed under Contract AF19628-212. Each seismometer signal is preamplifier and conditioned for FM transmission. The receiver recovers the signal and conditions it for recording, either directly or on magnetic tape. A computer controlled system for the calibration of seismometers is described. The end product is a response curve in terms of both amplitude and phase.
