• Anotaciones

• The Model 103 was the first Marine Valve receiver designed by AWA and manufactured by Australectric Co. for Australian ships. It consisted of one stage of RF, a detector and an audio stage.  The set covered reception from 300 to 6000 metres. Additional inductance could be added to increase the coverage to 15000 metres.

  The Model 103A was also available which covered 300 to 15000 metres.

  The radio incorporates a crystal detector which can be switched into circuit for use as an Emergency Crystal Receiver should the valve circuit fail.

  The receiver can be switched to receive either “undamped” or “damped” spark radio waves.
