 Original World War II War Department Technical Manual TM 11-1518 covering Radio Equipments RC-148, RC-148-B, and RC-148-C, dated October 20, 1944. This is a dedicated service manual covering theory, troubleshooting, maintenance, and repair procedures for these military radio systems. Originally classified Confidential, with later Restricted markings visible on the cover, the manual was intended for Signal Corps and depot-level technicians responsible for keeping critical communications equipment operational. Contains detailed technical information, circuit analysis, fault diagnosis procedures, and repair instructions not found in standard operator manuals. An excellent reference manual for collectors of WWII communications equipment, military electronics, and Signal Corps technical publications.
