POINT-TO-POINT COMMUNICATIONS AUGMENTED 4-WHEELS
Abstract
The augmented 4-wheels program was initiated to up-date the capability of the 4-wheels airtransportable, air traffic control system. As regards the HF point-to-point communications part of this system, this meant primarily the addition of single side-band techniques. At the same time, state-of-the-art improvements permitted the selection of much smaller and lighter components with the result that the transmitting and receiving functions are combined in one shelter. Since each radio equipment has four channel capability, as necessary to conform with ambient Aircom practices, two directional antennas are provided to enhance propagation reliability. Ranges up to 2500 miles are expected provided appropriate selection is made of operating frequency and circuit loading. Automatic quick tuning is provided in the proposed system with r-f channels selectable on a 0.1 kc basis. Ten telephone and ten teletypewriter circuits connect to the shelter. The proposed shelter is 84 x 84 x 154 inches in outside dimensions. The system includes primary power units and air conditioning units. Total space requirement for transport is 820 cubic feet. The system weight is estimated as less than 14,000 pounds. (Author)
