    The Canadian Marconi Transmitter No
      52 
	 
	Developed from the No 9 and No 9 Mk I sets and originally designated No 9 Mk II. 
	 
	The No 52 Set was developed for Brigade / Division communications and principally used for Division rear-link
      commands. 
	 
    It could be a ground station or vehicle-mounted.
    The principal improvements were in frequency range and RF output, making this unit far more successful than the No 9 Set it replaced.
       
     
    The improved frequency coverage was achieved by the use of three bands. 
	 
	The original No 9 Set had a single band from 1.875 to 5 MHz.   | 
    
         
     | 
   
 
  
     The No 52 Set had 3 bands from 1.75 to
      16 MHz. 
	 
    It was used from 1944 until its replacement in the 1950s by the Larkspur C11/R210. 
     
     The Frequency Coverage 
	1.75 to 16 Mc/s in three bands. 
    Band 1 : - 1.75
      to 4 Mc/s. 
    Band 2 : - 3.5 to 8 Mc/s. 
    Band 3 : -  7 to
      16 Mc/s. 
     
    Flick frequency selection is available on transmitter and receiver. 
	 
    The No 52 Set has three modes, low, medium and high, giving 2-4  15-20  18-30  45-75 and 75-100 Watts respectively. |

    Wireless Set 52 Transmitter Marconi WS No 52
      
  
      The 52 set Receiver and Transmitter information is somewhat integrated,
      separating out the TX & Rx is not practical as individual pages contain reference to both. 
     
    I have a total of 31 pages Electrical and Mechanical Engineering Regulations, covering both Transmitter and Receiver. 
     
    Plus
      31 pages on the Receiver only and 9 pages on the Transmitter only. 
     
      Total of 71 A4 Pages containing the following :-  
       Circuits Transmitter and Receiver 
      Basic layouts.  
      Typical meter readings.  
      Component lists.

       It is comprehensive and gives all the relevant information to renovate a 52 set Transmitter,
      I used this manual to renovate my 52 Set.
