They were a longwave search sets, installed on destroyers and larger ships to search for planes and surface vessels and for control of interception. All sets have an "A" scope, provision for Identification friend or foe (IFF) connections, and work with a gyro-compass repeater. SC-2 and SC-3 also have PPI scopes, remote PPI's, and built-in BL and BI*antennas.[2]
With antennas at 100', SC and SC-1 (without
bearing accuracy of SC and SC-21 is ± 5°; of SC-2 and SC-3, ± 3°. There is no elevation control on any of the sets, but height can be estimated roughly from positions of minimum signal strength.[2]
Shipment includes spares for each set. If separate generator is needed, it is included in shipment. Not air transportable.
Both SC and SC-1 have 5 components weighing a total of 1800 lbs. SC-2 has 6 components weighing a total of 3,000 pounds. Weights and dimensions of antenna assemblies are 450 lbs. 6'111/2" x 8'6" for SC and SC-1; 478 lbs. 4'6" x 15' for SC-2 and SC-3. Antennas should be mounted as high as possible, preferably 100 feet or more, above other superstructures.[2]
One operator per shift is minimum on all 3 sets. SC and SC-1 require primary power of 1500
