SCR-594 Radio Set

SCR-595* IFF Set MK III, 157-187 Mhz (I-band); AN 08-18-033, 1943. Set carried in airplanes and indicates whether a plane is friendly or enemy. Equip may be installed on ships or land vehicles, such as trucks. In such installations its operation is the same as for installations in planes. The equip does not operate at fixed radio freq. Its freq is continuously varied or swept over a range from 158 to 186 mc so that the transponder may answer any challenging signal within this range. The freq changes slowly from the lower limit (158 mc) to the upper limit (186 mc) and then returns rapidly to the lower limit. About 2.9 sec are needed for this complete cyc of which 2.5 sec are taken in sweeping slowly from the lower to upper limit. The remaining 0.4 sec is used in returning to the lower limit and is called the "flyback time". Principal components are: Aircraft Radio Receiver, Control Unit, Selector Unit, Antenna Assembly
