            detailing the story behind the event, artefacts manufactured by 
            Canadian Marconi Company, photographs and magazine articles.

          In May of 1898 a 24
          year old man by the name of 
           GUGLIELMO
          MARCONI registered Patent 7777 since which the world of radio
          communications has not looked back. This breakthrough added tuning
          circuits to guarantee the independence of simultaneous communications
          between more than one station. 
          On November 26, 1901 MARCONI 
           with
          his two assistants PAGET and KEMPT embarked in Liverpool for St.
          John's where they built another radio station. Marconi bought out the
          complete inventory of Peto and Radford English storage batteries from
          John Millen and Son in Montreal and had them shipped to Glace Bay. A
          few days later on on December 12th 1901 around 12.30, local time,
          MARCONI received three weak signals, 'dit' 'dit' 'dit' corresponding
          to letter S in MORSE code. 
            
           For
          the first time in the world electromagnetic waves had crossed an ocean
          and the rest is history which has been perfectly restored at the
          Hammond Museum of Radio. 
          This Marconi 10 inch spark transmitter was built and used at the
          turn of the century and is identical to the transmitter used on the
          Titanic to send the first SOS. 
          Matching receivers of the era would have been this Canadian Marconi
          crystal detector model that depicts the impress and robust
          construction of the time. 
            
          The crystal selection switch is visible at the top right. If one of
          the crystal connections became unstable the operator could quickly
          switch to hopefully a more stable piece of raw quartz wedged into the
          four machined retaining slots. 
          These Marconi radios where similar to those used aboard the Titanic
          on it's fateful Atlantic crossing and were recreated by the production
          company using Styrofoam for use in the the Titanic's Radio Room. 
          
           Other
          manufacturers were quick to licence Marconi's technology. One of the
          high end commercial receivers of the time was the IP501 pictured here
          in almost factory new condition. For improved performance, this
          receiver featured an input for an external detector. 
          Period advertisements for this beauty indicated the 501's weight
          was 87 pounds and carried a retail price for $595.00 which equalled
          the cost of two new family sedans.
