Abstract:

The translocation data transmitter is a medium-frequency, solid-state frequency-shift-keyed FSK transmitter designed to deliver a minimum power of 100 watts into a 16-foot whip antenna. The transmitter is designed to be operated in tactical situations with the translocation Doppler Receiving SetPortable Precision Differential DRSPPD receiver. All control of the transmitter is via the receiver front panel. Within the transmitter, there is a switch to control the data transmission rate. A choice of 1000bitsec or 100bitsec is available. Although the transmitter was designed primarily to be used with the Translocation System, it is capable of operating with any digitally clocked data, provided the proper command signals exist with the binary data. The unit with antenna and loading coils is light-weight approximately 25 pounds and compact comprising a chassis 15-12 by 7 by 6-12 inches. It contains its own primary power, which is supplied from 44 silver zinc cells. The transmitter can be attached directly to the base of the translocation receiver the entire unit is then capable of being carried by a single operator. Author
