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.
As with the No 9 Sets, 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.

As with the No 9 Set, ‘flick’ frequency selection is available on transmitter and receiver. The No 9 Set output 5W R/T or 10W CW.
The No 52 Set has three modes, low, medium and high, giving 2-4 and 2, 15-20 and 18-30 and 45-75 and 75-100 Watts respectively, making it up to 10 times more powerful.
