    | MCR1 Receiver Spy Radio 
 Designed during the second half of the war, the “Biscuit” was a full-range, highly sensitive,
      super heterodyne receiver with 5 miniature tubes.
 
 It was powered by a special battery, or with a separate power supply by AC/D.C. of 97 to 250 volts.
 
 This receiver was delivered in a 2-pound “Huntley-Palmer” cookie tin which also contained 4 interchangeable coil units, 3 batteries or 2 batteries and a power supply pack, 30 feet of aerial wire and 10
      feet of ground wire.
 
 A battery provided an average of 30 hours’ reception time.
 
 | 
      |  
    | Four knobs on the same side controlled aerial adjustment, sensitivity, regeneration for telegraph reception, and the frequency dial. 
 Dimensions:	3˝ X 2 X 8˝ inches
 
 Weight:	About 2 pounds
 
 Ten thousand of these sets were built and approximately half were widely distributed in the clandestine networks.
