Test of Model TAQ-4 Transmitting Equipment
Abstract
The appearance of the Model TAQ-4 equipment is excellent and high grade materials have been used in its construction. The design of the equipment is such that accessibility is good and servicing operations can be performed readily and with ease. The transmitter produces excellent output and the overall efficiency is high. The tuning operations required to obtain full output are simple and direct. The manufacturer has supplied a new type of control circuit whereby the equipment may be started at any time by means of a. c. without the necessity of maintaining the control rectifier in an operative condition at all times. This method of operation is very desirable. Certain features of operation were not entirely satisfactory, but through the medium of comparatively minor modifications these undesirable conditions may be overcome. The equipment fails to operate in ambient temperatures between zero and 5 degrees Centigrade due to the fact that the mercury vapor rectifier tubes cease operation. This condition can be corrected by supplying tube heaters of greater capacity than those ow provided. The only other serious operational failure was caused by the failure of the auxiliary plate rectifier transformer. Certain corrections, modifications, and changes in the existing equipment are indicated to provide for greater safety factors under ship board conditions of operation, greater ease in handling the equipment and to correct minor mechanical defects.
