Modulation: five steps from 150 to 5000 Hz, plus external; up to 50 kHz deviation. 500 kHz Xtal internal calibrator with self contained beat note monitor speaker. Modular design with four major subassemblies: power supply, AF modulator, Xtal calibrator, RF generator. Projection tuning dial with 1300 divisions, 2 kHz resolution over the high frequency band.
  The equipment is heavy, due to its triple shielding: the panel, the cabinet, the RF sub-unit are all shielded by three layers of hard, silver plated, steel; all the vent holes are covered by a fine silvered mesh. TM-11-317 is the technical manual. Such units were at least by Detrola International in 1944. Well possible that it was started in 1942.
