Description: Radio Receiving Set FRR-24 is a double-conversion superhetrodyne type diversity receiver for use at shore stations in point-to-point communication. It can receive signals in single-channel, space- or frequency-dual-, or triple-diversity operations, such as double-sideband radiotelephone, on-off keyed radiotelegraph, and frequency- shift-keyed telegraph to operate single-channel teletypewriters at 24.5 dot cycles and/or up to four-chanel multiplex at 98 dot cycles. The functions and performance of this equipment are similar to those of Radio Receiving Sets FRR-10 and FRR-37, except that the FRR-24 uses both dual- or triple-diversity operation and cannot receive single-sideband suppressed carrier signals. The complete equipment is contained in four rack cabinets permanently conected together.
